 |
|
Cairo use double value coordinates.
This is important because there are transform, scale and rotate
But gtkD remove CairoRectangle and use GdkRectangle instead, which use integer value.
I don't understand why you did that.
Why not just use opCast to convert from GdkRectangle to CairoRectangle?
Besides, Cairo also support windows and mac surface, it's weird that Cairo import GDK classes everywhere. |

The function that excepts the CairoRectangle should still there, there are only a few gdk_cairo functions aded to cairo.Context.

as far as i know only cairo.Context imports gdk classes for the gdk_cairo_ functions that are added to that class. |
