Declaration [src]

gdk_texture_download (
  GdkTexture* texture,
  guchar* data,
  gsize stride

Description [src]

Downloads the texture into local memory.

This may be an expensive operation, as the actual texture data may reside on a GPU or on a remote display server.

The data format of the downloaded data is equivalent to CAIRO_FORMAT_ARGB32, so every downloaded pixel requires 4 bytes of memory.

Downloading a texture into a Cairo image surface:

surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32,
                                      gdk_texture_get_width (texture),
                                      gdk_texture_get_height (texture));
gdk_texture_download (texture,
                      cairo_image_surface_get_data (surface),
                      cairo_image_surface_get_stride (surface));
cairo_surface_mark_dirty (surface);


data An array of guchar

Pointer to enough memory to be filled with the downloaded data of texture.

 The data is owned by the caller of the function.
stride gsize

Rowstride in bytes.
