= How to build *resvg*
== Intro
*resvg* doesn't include a 2D graphics library and uses external ones.
Their support is implemented separately, therefore we call them _backends_.
You can build them separately or together. +
At the moment, there are four backends: https://www.qt.io/[Qt],
https://www.cairographics.org/[cairo], https://skia.org/[Skia] and
https://github.com/jrmuizel/raqote[raqote].
Since *resvg* is a https://www.rust-lang.org/[Rust] library, you should build it via `cargo`. +
To enable a backend use the `--features` option:
```bash
# Build with a Qt backend
cargo build --release --features="qt-backend"
# or with a cairo backend
cargo build --release --features="cairo-backend"
# or with a raqote backend
cargo build --release --features="raqote-backend"
# or with a skia backend
cargo build --release --features="skia-backend"
# or with all
cargo build --release --all-features
```
== Dependencies
* The library requires the latest stable
https://www.rust-lang.org/tools/install[Rust].
* All backends depend on https://github.com/harfbuzz/harfbuzz[harfbuzz],
which will be built automatically by `cargo` and will be linked statically.
https://cmake.org/download/[CMake] is required as a build-time dependency.
* The _Qt backend_ requires only `QtCore` and `QtGui` libraries. +
Technically, any Qt 5 version should work, but we only support Qt >= 5.6.
* The _cairo backend_ requires https://www.cairographics.org/[cairo] >= 1.12.
* The _raqote backend_ doesn't require any external dependencies.
* The _skia backend_ requires the https://skia.org/[Skia] itself.
* (Linux, runtime) _fontconfig_. Specifically `fc-match`.
== Windows
=== Qt backend via MSVC
Install:
* `stable-x86_64-pc-windows-msvc` https://www.rust-lang.org/tools/install[Rust] target.
* https://cmake.org/download/[CMake] (required to build harfbuzz).
* Qt built with MSVC via an http://download.qt.io/official_releases/online_installers/qt-unified-windows-x86-online.exe[official installer].
Build using `x64 Native Tools Command Prompt for VS 2017` shell:
```batch
set PATH=%userprofile%\.cargo\bin;%PATH%
set QT_DIR=C:\Qt\5.12.0\msvc2017_64
cargo.exe build --release --features "qt-backend"
```
Instead of `msvc2017_64` you can use any other Qt MSVC build. Even 32-bit one.
We are using Qt 5.12.0 just for example.
=== Qt backend via MinGW
Install:
* `stable-x86_64-pc-windows-gnu` https://www.rust-lang.org/tools/install[Rust] target.
* https://cmake.org/download/[CMake] (required to build harfbuzz).
* Qt built with MinGW 64-bit via an http://download.qt.io/official_releases/online_installers/qt-unified-windows-x86-online.exe[official installer].
Build using `cmd.exe`:
```batch
set PATH=C:\Qt\5.12.0\mingw73_64\bin;C:\Qt\Tools\mingw730_64\bin;%userprofile%\.cargo\bin;%PATH%
set QT_DIR=C:\Qt\5.12.0\mingw73_64
cargo.exe build --release --features "qt-backend"
```
Instead of `mingw73_64` you can use any other Qt mingw build.
We are using Qt 5.12.0 just for example.
=== cairo backend via MSYS2
Install `stable-x86_64-pc-windows-gnu` https://www.rust-lang.org/tools/install[Rust] target.
And then:
```bash
pacman -S mingw-w64-x86_64-cmake mingw-w64-x86_64-cairo
cargo.exe build --release --features "cairo-backend"
```
You can use i686 target in the same way.
=== raqote backend via MSVC
Install:
* `stable-x86_64-pc-windows-msvc` https://www.rust-lang.org/tools/install[Rust] target.
* https://cmake.org/download/[CMake] (required to build harfbuzz).
Build using `x64 Native Tools Command Prompt for VS 2017` shell:
```batch
set PATH=%userprofile%\.cargo\bin;C:\Program Files\CMake\bin;%PATH%
cargo.exe build --release --features "raqote-backend"
```
=== raqote backend via MSYS2
Install `stable-x86_64-pc-windows-gnu` https://www.rust-lang.org/tools/install[Rust] target.
And then:
```bash
# install harfbuzz dependencies:
pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-cmake
cargo.exe build --release --features "raqote-backend"
```
You can use i686 target in the same way.
=== Skia backend via MSVC
Install:
* `stable-x86_64-pc-windows-msvc` https://www.rust-lang.org/tools/install[Rust] target.
* https://cmake.org/download/[CMake] (required to build harfbuzz).
* Skia itself (we assume that you have already built one).
`SKIA_DIR` should point to a Skia directory that contains the Skia `include` directory.
`SKIA_LIB_DIR` should point to a Skia directory that contains `skia.dll`.
Build using `x64 Native Tools Command Prompt for VS 2017` shell:
```batch
set PATH=%userprofile%\.cargo\bin;C:\Program Files\CMake\bin;%PATH%
set SKIA_DIR=path
set SKIA_LIB_DIR=path
cargo.exe build --release --features "skia-backend"
```
== Linux

```
If you don't want to use a system Qt, you can alter it with the `PKG_CONFIG_PATH` variable.
```bash
PKG_CONFIG_PATH='/path_to_qt/lib/pkgconfig' cargo build --release --features "qt-backend"
```

```
=== Skia backend
We assume that you have already built Skia itself.
Install `harfbuzz` using your distributive's package manager.
On Ubuntu you can install it via:
```
sudo apt install libharfbuzz-dev
```
`SKIA_DIR` should point to a Skia directory that contains the Skia `include` directory.
`SKIA_LIB_DIR` should point to a Skia directory that contains `libskia.so`.
```sh
SKIA_DIR=path SKIA_LIB_DIR=path cargo build --release --features "skia-backend"
```
== macOS
=== Qt backend
Using https://brew.sh/[homebrew]:
```bash
brew install qt
QT_DIR=/usr/local/opt/qt cargo build --release --features "qt-backend"
```
Or an
http://download.qt.io/official_releases/online_installers/qt-unified-mac-x64-online.dmg[official Qt installer]:

```sh
SKIA_DIR=path SKIA_LIB_DIR=path cargo build --release --features "skia-backend"
```
== For maintainers
*resvg* consists of 4 parts:
- the Rust library (link:./src[src])
- the C library/bindings (link:./capi[capi])
- the CLI tool to render SVG (link:./tools/rendersvg[tools/rendersvg])
- the CLI tool to simplify SVG (link:./tools/usvg[tools/usvg])
All of them are optional and each one, except `usvg`, can be built with a specific backend.
No need to build `rendersvg` for each backend separately since it has a CLI switch
to choose which one to use in runtime.
Not sure how the Rust library can be packaged, but the C libraries should probably be built
separately.
So the final package can look like this:
```
/bin/rendersvg (does not depend on libresvg-*.so)
/bin/usvg (completely optional)
/include/resvg/resvg.h (from capi/include)
/include/resvg/ResvgQt.h (from capi/include, only for Qt backend)
/lib/libresvg-cairo.so
/lib/libresvg-qt.so
/lib/libresvg-raqote.so
/lib/libresvg-skia.so
```

All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/)
and this project adheres to [Semantic Versioning](http://semver.org/).
This changelog also contains important changes in dependencies.
## [Unreleased]
## [0.8.0] - 2019-08-17
### Added
- A [Skia](https://skia.org/) backend thanks to
[JaFenix](https://github.com/JaFenix).
- `feComponentTransfer` support.
- `feColorMatrix` support.
- A better CSS support.
- An `*.otf` fonts support.
- (usvg) `dx`, `dy` are supported inside `textPath` now.
- Use a box blur for `feGaussianBlur` with `stdDeviation`>=2.
This is 4-8 times faster than IIR blur.
Thanks to [Shnatsel](https://github.com/Shnatsel).
### Changed
- All backends are using the `image` crate for raster images loading now.
- Use `pico-args` instead of `gumdrop` to reduced the build time of `tools/rendersvg`
and `tools/usvg`.
- (usvg) The `xmlwriter` is used for SVG generation now.
Almost 2x faster than generating an `svgdom`.
- (usvg) Optimize font database initialization. Almost 50% faster.
- Use a lower PNG compression ratio to speed up PNG generation.
Depending on a backend and image can be 2-4x faster.
- `OutputImage::save` -> `OutputImage::save_png`.
- (usvg) `Path::segments` -> `Path::data`.
- Cairo backend compilation is 2x faster now due to overall changes.
- Performance improvements (Oxygen Icon theme SVG-to-PNG):
- cairo-backend: 22% faster
- qt-backend: 20% faster
- raqote-backend: 34% faster
### Fixed
- (qt-api) A default font resolving.
- (usvg) `baseline-shift` processing inside `textPath`.
- (usvg) Remove all `tref` element children.
- (usvg) `tref` with `xml:space` resolving.
- (usvg) Ignore nested `tref`.

### Added
- New text layout implementation:
- `textPath` support.
- `writing-mode` support, aka vertical text.
- [Text BIDI reordering](http://www.unicode.org/reports/tr9/).
- Better text shaping.

[jrmuizel](https://github.com/jrmuizel). Still experimental.
### Changed
- Text will be converted into paths on the `usvg` side now.
- (resvg) Do not rescale images before rendering. This is faster and better.
- (usvg) An `image` element with a zero or negative size will be skipped now.
Previously, a linked image size was used, which is incorrect.
- Geometry primitives (`Rect`, `Size`, etc) are immutable and always valid now.
- (usvg) The default `color-interpolation-filters` attribute will not be exported now.
### Removed
- (usvg) All text related structures and enums. Text will be converted into `Path` now.

--------------------------------
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
(a) under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or
as part of a Larger Work; and
(b) under Patent Claims of such Contributor to make, use, sell, offer
for sale, have made, import, and otherwise transfer either its
Contributions or its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
(a) for any code that a Contributor has removed from Covered Software;
or
(b) for infringements caused by: (i) Your and any other third party's
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
(c) under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to

[](https://travis-ci.org/RazrFalcon/resvg)
[](https://crates.io/crates/resvg)
[](https://docs.rs/resvg)
*resvg* is an [SVG](https://en.wikipedia.org/wiki/Scalable_Vector_Graphics) rendering library.
## Purpose
*resvg* can be used as:
- a Rust library
- a C library (see [capi](./capi))
- a CLI application (see [tools/rendersvg](./tools/rendersvg))
to render SVG files based on a
[static](http://www.w3.org/TR/SVG11/feature#SVG-static)
[SVG Full 1.1](https://www.w3.org/TR/SVG/Overview.html) subset to raster images or
to a backend's canvas (e.g. to a QWidget via QPainter).
The core idea is to make a fast, small, portable, multiple-backend SVG library
designed for edge-cases.
Another major difference from other SVG rendering libraries is that *resvg* does a lot
of preprocessing before rendering. It converts an input SVG into a simplified one
called [Micro SVG](./docs/usvg_spec.adoc) and only then it begins rendering.
So it's very easy to implement a new rendering backend.
And you can also access *Micro SVG* as XML directly via [usvg](./tools/usvg) tool.
## SVG support
*resvg* is aiming to support only the [static](http://www.w3.org/TR/SVG11/feature#SVG-static)
SVG subset; e.g. no `a`, `script`, `view` or `cursor` elements, no events and no animations.
A list of unsupported features can be found [here](docs/unsupported.md).
[SVG Tiny 1.2](https://www.w3.org/TR/SVGTiny12/) and [SVG 2.0](https://www.w3.org/TR/SVG2/)
are not supported and not planned.
Results of the static subset of the [SVG test suite](https://www.w3.org/Graphics/SVG/Test/20110816/):
Results of the [resvg test suite](https://github.com/RazrFalcon/resvg-test-suite):
You can find a complete table of supported features
[here](https://razrfalcon.github.io/resvg-test-suite/svg-support-table.html).
It also includes alternative libraries.
## Performance
Note that all tested applications have a different SVG support, which impacts the performance.
Also, we do not test against Chrome, Firefox, Inkscape and Batik because they have a huge startup time.
- Elementary Icon Theme contains 3417 files.
- Qt backend is slow because `QRasterPaintEngine` is slow.
- The Oxygen icon theme contains 4947 files.
- All images were converted from `.svgz` to `.svg` beforehand.
- `resvg` is slower than `librsvg` because the Oxygen icon theme uses Gaussian blur heavily,
and `librsvg` has a faster blur implementation.
Also, `librsvg` uses native `cairo` clipping, [which is incorrect](https://razrfalcon.github.io/resvg-test-suite/svg-support-table.html#e-clipPath) but faster.
- QtSvg doesn't support `filter`, `clipPath`, `mask` and `pattern` that are heavily used in the Oxygen icon theme.
So it's actually very slow.
## Project structure
- `resvg` – rendering backends implementation
- [`usvg`](./usvg) – an SVG simplification tool
- [`roxmltree`](https://github.com/RazrFalcon/roxmltree) – a DOM-like XML tree
- [`xmlparser`](https://github.com/RazrFalcon/xmlparser) – an XML parser
- [`svgtypes`](https://github.com/RazrFalcon/svgtypes) – SVG types parser and writer
- [`simplecss`](https://github.com/RazrFalcon/simplecss) – a simple CSS2 parser
- [`ttf-parser`](https://github.com/RazrFalcon/ttf-parser) – a TrueType/OpenType parser
- [`xmlwriter`](https://github.com/RazrFalcon/xmlwriter) – a simple XML writer
- [`rctree`](https://github.com/RazrFalcon/rctree) – a DOM-like tree
- [`resvg-qt`](./bindings/resvg-qt) – minimal bindings to [Qt]
- [`resvg-skia`](./bindings/resvg-skia) – minimal bindings to [Skia]
All other dependencies aren't written by me for this project.
## Directory structure
- `bindings` – minimal bindings to Qt and Skia used by *resvg*
- `capi` – C interface for *resvg*
- `docs` – basic documentation
- `examples` – usage examples for *resvg* as a library
- `src` – source code
- `testing-tools` – scripts used for testing
- `tools` – useful tools
- `usvg` – an SVG simplification library used by *resvg*
## Safety
- The library must not panic. Any panic should be considered a critical bug and should be reported.
There are only a few methods that can produce a panic.
- The core library structure (see above) does not use any `unsafe`,
but since all backends are implemented via FFI, we are stuck with `unsafe` anyway.
Also, `usvg` uses unsafe for fonts memory mapping.

:toc:
== Intro
SVG Micro represents a strip down SVG Full 1.1 subset.
Here is the main differences between SVG Full and SVG Micro.
- No XML DTD.
- No CSS.
- `use`, `marker` and nested `svg` will be resolved.
- Simplified path notation. Only absolute MoveTo, LineTo, CurveTo
and ClosePath segments are allowed.
- No inheritable attributes.
- No `xlink:href`, except the `image` element.
- No recursive references.
- Only valid elements and attributes.
- No unused elements.
- No redundant groups.
- No units.
- No `style` attribute.
- Default attributes are implicit.
You can use
https://github.com/RazrFalcon/resvg/tree/master/usvg[usvg]
to convert a random SVG into a SVG Micro almost losslessly.
== Elements
[[svg-element]]
=== The `svg` element
The `svg` element is the root element of the document.
It's defined only once and can't be nested, unlike by the SVG spec.

[[g-element]]
=== The `g` element
The group element indicates that a new canvas should be created.
All group's children elements will be rendered on it and then merged into
the parent canvas.
Since it's pretty expensive, especially memory wise, _usvg_
will remove as many groups as possible.
And all the remaining one will indicate that a new canvas must be created.
A group can have no children when it has a `filter` attribute.
A group will have at least one of the attributes present.
*Children:*
* <>

*Attributes:*
* `id` = < >>? +

The attributes below are the same for all filter primitives.
* `color-interpolation-filters` = `sRGB`? +
Default: linearRGB
* `x` = < >>?
* `y` = < >>?
* `width` = < >>?
* `height` = < >>?
* `result` = < >>
The `x`, `y`, `width` and `height` attributes can be omited.
SVG has a pretty complex
https://www.w3.org/TR/SVG11/filters.html#FilterPrimitiveSubRegion[rules of resolving them]
and I don't fully understand them yet.
Neither do others, because they are pretty poorly implemented.

* `in` = < >>
* `in2` = < >>
* `mode` = `normal | multiply | screen | darken | lighten`
* <>

** For `type=matrix`, contains 20 numbers.
** For `type=saturate`, contains a single number in a 0..1 range.
** For `type=hueRotate`, contains a single number.
** Not present for `type=luminanceToAlpha`.
* <>
