Name Description Size
cairo-xlib-utils.h This callback encapsulates Xlib-based rendering. We assume that the execution of the callback is equivalent to compositing some RGBA image of size (bounds_width, bounds_height) onto the drawable at offset (offset_x, offset_y), clipped to the union of the clip_rects if num_rects is greater than zero. This includes the assumption that the same RGBA image is composited if you call the callback multiple times with the same closure, display and visual during a single cairo_draw_with_xlib call. @return True on success, False on non-recoverable error 5112

Fast-paths may still be taken even if GoodAlignmentLog2() is not met, in some conditions. 3933

gfxBlur.cpp 48073
gfxBlur.h Implementation of a triple box blur approximation of a Gaussian blur. A Gaussian blur is good for blurring because, when done independently in the horizontal and vertical directions, it matches the result that would be obtained using a different (rotated) set of axes. A triple box blur is a very close approximation of a Gaussian. Creates an 8-bit alpha channel context for callers to draw in, spreads the contents of that context, blurs the contents, and applies it as an alpha mask on a different existing context. A spread N makes each output pixel the maximum value of all source pixels within a square of side length 2N+1 centered on the output pixel. A temporary surface is created in the Init function. The caller then draws any desired content onto the context acquired through GetContext, and lastly calls Paint to apply the blurred content as an alpha mask. 7910
gfxColor.h Fast approximate division by 255. It has the property that for all 0 <= n <= 255*255, GFX_DIVIDE_BY_255(n) == n/255. But it only uses two adds and two shifts instead of an integer division (which is expensive on many processors). equivalent to ((v)/255) 2152

gfxGDIFontList.h List of different types of fonts we support on Windows. These can generally be lumped in to 3 categories where we have to do special things: Really old fonts bitmap and vector fonts (device and raster), Type 1 fonts, and TrueType/OpenType fonts. This list is sorted in order from least prefered to most prefered. We prefer Type1 fonts over OpenType fonts to avoid falling back to things like Arial (opentype) when you ask for Helvetica (type1) 11682
gfxGlyphExtents.cpp 4844
gfxGlyphExtents.h This stores glyph bounds information for a particular gfxFont, at a particular appunits-per-dev-pixel ratio (because the compressed glyph width array is stored in appunits). We store a hashtable from glyph IDs to float bounding rects. For the common case where the glyph has no horizontal left bearing, and no y overflow above the font ascent or below the font descent, and tight bounding boxes are not required, we avoid storing the glyph ID in the hashtable and instead consult an array of 16-bit glyph XMost values (in appunits). This array always has an entry for the font's space glyph --- the width is assumed to be zero. 5995

(Note that aNativeRect will be ignored if the gfxQuartzNativeDrawing uses the target DrawTarget directly.)
