RGtk2 (version 2.8.8)

gdkDrawPixbuf: 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.
