nim-lang / cairo Goto Github PK

Browsed the examples, images are drawn from the scripts. But what should I do if I want to draw in a window?

https://github.com/freedesktop/cairo/blob/master/src/cairo-tee-surface.c

Are there any plans for adding support for tee surfaces? Is there some reason they are not supported? Never used them, but they could come in handy for a project i'm working on, so just wondering. Thanks

Please add to cairo.nim

# new since 1.10
proc cairo_surface_create_for_rectangle*(target: PSurface, x,y,w,h: float64):
    PSurface {.cdecl, importc: "cairo_surface_create_for_rectangle", libcairo.}

Thanks!

Currently cairowin32 does not compile because it can't find the 'windows' module.

I'm not sure what the plan is with the windows API wrapper, but I suppose a quick fix is to add a dependency on the 'oldwinapi' package.

(I'm not sure how advanced the nimble dependency system is, but it would be nice if the dependency was only valid when using nimble on windows)

Hint: cairowin32 [Processing]
c:\documents and settings\administrator.nimble\pkgs\cairo-1.0\cairowin32.nim(20
, 52) Error: undeclared identifier: 'pLOGFONTW'

should change pLOGFONTW to PLOGFONTW, and fixed!

The very first code given (the arc test) in the README is incomplete.
Please replace the code snippets with links to the repository tests.

in order to do these are the steps that need to be taken:

1. types and procs interfacing directly with libcairo need to keep their original names
   example type example proc

2. The "higher level" user api of this library will get shorter names like Surface, imageSurfaceCreate.

3. destructors will be attached to these types. it will look like this:

type
  Surface = object
    data: PSurface

`=destroy`(surface: var Surface)
`=`(dst: var Surface, src: Surface) {.error.}

These changes will break the api of this library but will allow the user to forget the closing of resources.
