void gdk_gl_texture_builder_set_format ( GdkGLTextureBuilder* self, GdkMemoryFormat format )
Sets the format of the texture. The default is
The format is the preferred format the texture data should be downloaded to. The
format must be supported by the GL version of
GDK’s texture download code assumes that the format corresponds to the storage
parameters of the GL texture in an obvious way. For example, a format of
GDK_MEMORY_R16G16B16A16_PREMULTIPLIED is expected to be stored as
GDK_MEMORY_G8A8 is expected to be stored as
Setting the right format is particularly useful when using high bit depth textures to preserve the bit depth, to set the correct value for unpremultiplied textures and to make sure opaque textures are treated as such.
Non-RGBA textures need to have swizzling parameters set up properly to be usable in GSK’s shaders.
