A negative or means an unbounded dimension - both cannot be negative. If is 90, 180 or 270 we rotate first so that the rotated pixbuf is fitted in the rectangle. Unless is True we don't stretch images smaller than the given rectangle. If has an alpha channel it gets a checkboard background. ii'iiZis#checkered bg for transparent imagesiÿiiwwwi™™™iiÿÿÿi´(iZi(tmaxt get_widtht get_heightt get_has_alphaRtcomposite_color_simpletgtktgdkt INTERP_TILEStfloattintt scale_simplet rotate_simpletPIXBUF_ROTATE_CLOCKWISEtPIXBUF_ROTATE_UPSIDEDOWNtPIXBUF_ROTATE_COUNTERCLOCKWISE(tsrctwidththeighttscale_uptrotationt src_widtht src_height((sE/home/sork/Pontus/Programmering/Python/Comix/comix-4.0.4/src/image.pytfit_in_rectangle sD       "    #!!       cCsÌ|djo d}n|djo d}n|d8}t|dƒ}t|dƒ}|iƒ}|iƒ}|iƒ} |iƒ} |djo||}}n|djo| | } } n|| } t||| dƒ} t| || dƒ} t|t|t|ƒ| t|ƒƒƒ}t| t|t| ƒ| t| ƒƒƒ}|| jo| | |7} n || jo| | |7} nt|t| ƒ|||ƒt|t| ƒ|||ƒfS( sÚScale two pixbufs so that they fit together (side-by-side) into a rectangle with dimensions x , with a 2 px gap. If one pixbuf does not use all of its allotted space, the other one is given it, so that the pixbufs are not necessarily scaled to the same percentage. The pixbufs are rotated according to the angles in and before they are scaled.
