Some parts based on win32.cpp by Lauris Kaplinski lauri.nosp@m.s@ka.nosp@m.plins.nosp@m.ki.c.nosp@m.om.

Was a part of Inkscape in the past (or will be in the future?) Not in current trunk. (4/19/2012)

Limitations of this code:

1. Images lose their rotation, one corner stays in the same place.
2. Transparency is lost on export. (A limitation of the WMF format.)
3. Probably messes up if row stride != w*4
4. There is still a small memory leak somewhere, possibly in a pixbuf created in a routine that calls this one and passes px, but never removes the rest of the pixbuf. The first time this is called it leaked 5M (in one test) and each subsequent call leaked around 200K more. If this routine is reduced to if(1)return(0); and called for a single 1280 x 1024 image then the program leaks 11M per call, or roughly the size of two bitmaps. provides indirect link to image object

DIBColors Enumeration

(Optional) bitmapbuffer (U_BITMAPINFO section)

size in bytes of px

(Optional) bitmapbuffer (U_BITMAPINFO section)

Parameters

rgba_px	not used
w	array of pixel values, Gdk::Pixbuf bitmap format
h	width of bitmap
rs	height of bitmap
tf_rect	row stride (normally w*4)
style	affine transform only used for defining location and size of rect, for all other transforms, use the one from m_tr_stack
