With current build procedure, it is hard to update native lib to latest version. Just found a shell-based solution, which is better than current VC++ project solution:

https://github.com/preshing/cairo-windows

Cairo.ImageSurface.WriteToPng does nothing when the specified path contains non-ASCII characters.

for #1

environment: Win10 x64, VS2017 15.0.27130.2020

Error message from package manager:

Error occurred while restoring NuGet packages: The local source 'D:\my\CairoSharp\NuGet-Packed' doesn't exist.

Error message from package manager:

CS0518 Predefined type 'System.Object' is not defined or imported CairoDemo D:\my\CairoSharp\demos\CairoDemo\Program.cs
(and many more like above)

We must ensure that the following process is never interrupted by any errors that is hard to solve.

1. git clone
2. build solution
3. debug/release run demo projects

Some hard errors that should be avoided:

1. Windows SDK version not right: users need to download the required windows SDK, which is really time-consuming.
2. .NET Framework / .NET Core not installed: time-consuming
3. Provide pre-built dll/so if a developer don't want to build native libraries by him/herself, which is time-consuming.

Target: Clone, build C# projects and run demos seamlessly on Win10 with VS2017 only.

• Linux

This is an issue from Brad and is to be reproduced.

Context context;
Matrix matrix = context.FontMatrix;

This will cause an exception to be thrown. It looks like it is coming from the Native code. I wasn’t sure how you were sourcing the cairod.dll so I stopped digging there.

Hi

I have tried to download the source code and build it, but I ran into a problem with this when building the native dependencies. I get the following output from build:
1>cairo-surface-observer.obj : error LNK2001: unresolved external symbol __cairo_script_context_create_internal
1>cairo-surface-observer.obj : error LNK2001: unresolved external symbol __cairo_script_context_attach_snapshots
1>C:\Users\fazal\Libraries\CairoSharp\source\Native\Output\bin\win-x64\cairo.dll : fatal error LNK1120: 2 unresolved externals

Any help with this would be greatly appreciated.

Is it possible to draw text using one of the pre-installed Windows system fonts? I read in the cairo reference manual a little bit, and it seems like it somehow depends on which font backend is enabled in cairo. Seems to be a fairly complex topic.

I've downloaded the release https://github.com/zwcloud/CairoSharp/releases/tag/dotnet_4.5 and found that the solution does not compile due to following 4 files are missing from the .zip and the tar.gz:

• Demo\Windows\WinFormDemo\Program.cs
• Demo\Windows\WinFormDemo\Form1.Designer.cs
• Demo\Windows\DrawPngInMemory\Program.cs
• Demo\Windows\DrawPngInMemory\Form1.cs

Take care,
Martin

I've found it but on gtk+. I need on Gtk#
