```
import cairo.ImageSurface;
ImageSurface.createForData(c,cairo.FORMAT_ARGB32,256,256,256*4);
```
You need to import the ImageSurface module, and the
createForData function is in the ImageSurface class which is in
the cairo.ImageSurface module.
Thanks, that was the problem!
Now i can read the buffer from a png image and save the buffer as
a file:
auto pngImage =
ImageSurface.createFromPng("C:\\Users\\Standardbenutzer\\Desktop\\DSC00564-1.png");
auto buffer = pngImage.getData();
auto cS = ImageSurface.createForData(buffer,
cairo_format_t.ARGB32,pngImage.getWidth(),pngImage.getHeight(),pngImage.getStride());
cS.writeToPng("test.png");
but how do i do that with my GTKD Context in my "drawCallback()"
function?
