Functions

detectNinePatch bool detectNinePatch(): detect nine patch using image 1-pixel border (see Android documentation)
drawFragment void drawFragment(int x, int y, DrawBuf src, Rect srcrect): draw source buffer rectangle contents to destination buffer
drawGlyph void drawGlyph(int x, int y, Glyph* glyph, uint color): Undocumented in source. Be warned that the author may not have intended to support it.
drawRescaled void drawRescaled(Rect dstrect, DrawBuf src, Rect srcrect): draw source buffer rectangle contents to destination buffer rectangle applying rescaling
fillRect void fillRect(Rect rc, uint color): Undocumented in source. Be warned that the author may not have intended to support it.
scanLine uint* scanLine(int y): returns pointer to ARGB scanline, null if y is out of range or buffer doesn't provide access to its memory

ninePatch const(NinePatch)* ninePatch [@property getter]: get nine patch information pointer, null if this is not a nine patch image buffer
ninePatch NinePatch* ninePatch [@property setter]: set nine patch information pointer, null if this is not a nine patch image buffer
hasNinePatch bool hasNinePatch [@property getter]: check whether there is nine-patch information available for drawing buffer
detectNinePatch bool detectNinePatch(): override to detect nine patch using image 1-pixel border; returns true if 9-patch markup is found in image.
width int width [@property getter]: returns current width
height int height [@property getter]: returns current height
clipRect Rect clipRect [@property getter]: returns clipping rectangle, when clipRect.isEmpty == true -- means no clipping.
clipOrFullRect Rect clipOrFullRect [@property getter]: returns clipping rectangle, or (0,0,dx,dy) when no clipping.
clipRect Rect clipRect [@property setter]: sets new clipping rectangle, when clipRect.isEmpty == true -- means no clipping.
intersectClipRect Rect intersectClipRect [@property setter]: sets new clipping rectangle, when clipRect.isEmpty == true -- means no clipping.
applyClipping bool applyClipping(Rect rc): apply clipRect and buffer bounds clipping to rectangle
applyClipping bool applyClipping(Rect rc, Rect rc2): apply clipRect and buffer bounds clipping to rectangle; if clippinup applied to first rectangle, reduce second rectangle bounds proportionally.
beforeDrawing void beforeDrawing(): reserved for hardware-accelerated drawing - begins drawing batch
afterDrawing void afterDrawing(): reserved for hardware-accelerated drawing - ends drawing batch
bpp int bpp [@property getter]: returns buffer bits per pixel
resize void resize(int width, int height): resize buffer
fill void fill(uint color): fill the whole buffer with solid color (no clipping applied)
fillRect void fillRect(Rect rc, uint color): fill rectangle with solid color (clipping is applied)
drawGlyph void drawGlyph(int x, int y, Glyph* glyph, uint color): draw 8bit alpha image - usually font glyph using specified color (clipping is applied)
drawFragment void drawFragment(int x, int y, DrawBuf src, Rect srcrect): draw source buffer rectangle contents to destination buffer
drawRescaled void drawRescaled(Rect dstrect, DrawBuf src, Rect srcrect): draw source buffer rectangle contents to destination buffer rectangle applying rescaling
drawImage void drawImage(int x, int y, DrawBuf src): draw unscaled image at specified coordinates
transformColors DrawBuf transformColors(ColorTransform transform): create drawbuf with copy of current buffer with changed colors (returns this if not supported)
clear void clear(): Undocumented in source. Be warned that the author may not have intended to support it.
