AffineTransform in gtk

I need to undergo some affinetransformation operation using gtk framework.

i found cairo but that does not solve my requirements. i need to crate transformation object and undergo some operations as under:

1. [tranform1 translateXBy:2.5 yBy:3.8];
2. [transform1 rotateByDegrees:23.0];
3. [transform1 appendTransform:trans开发者_如何学JAVAform2];

where transform1, transform2 are objects of AffineTransformation.

Regards, iSight
