gdkDrawPixbuf {RGtk2}R Documentation

gdkDrawPixbuf

Description

Renders a rectangular portion of a pixbuf to a drawable. The destination drawable must have a colormap. All windows have a colormap, however, pixmaps only have colormap by default if they were created with a non-NULL window argument. Otherwise a colormap must be set on them with gdkDrawableSetColormap.

Usage

gdkDrawPixbuf(object, gc = NULL, pixbuf, src.x, src.y, dest.x, dest.y, width = -1, height = -1, dither = "GDK_RGB_DITHER_NORMAL", x.dither = 0, y.dither = 0)

Arguments

object [GdkDrawable] Destination drawable.
gc [GdkGC] a GdkGC, used for clipping, or NULL
pixbuf [GdkPixbuf] a GdkPixbuf
src.x [integer] Source X coordinate within pixbuf.
src.y [integer] Source Y coordinates within pixbuf.
dest.x [integer] Destination X coordinate within drawable.
dest.y [integer] Destination Y coordinate within drawable.
width [integer] Width of region to render, in pixels, or -1 to use pixbuf width.
height [integer] Height of region to render, in pixels, or -1 to use pixbuf height.
dither [GdkRgbDither] Dithering mode for GdkRGB.
x.dither [integer] X offset for dither.
y.dither [integer] Y offset for dither.

Details

On older X servers, rendering pixbufs with an alpha channel involves round trips to the X server, and may be somewhat slow.

The clip mask of gc is ignored, but clip rectangles and clip regions work fine.
