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`` | Destination drawable.
``gc`` | a `GdkGC`, used for clipping, or `NULL`. [ allow-none ]
``pixbuf`` | a `GdkPixbuf`
``src.x`` | Source X coordinate within pixbuf.
``src.y`` | Source Y coordinates within pixbuf.
``dest.x`` | Destination X coordinate within drawable.
``dest.y`` | Destination Y coordinate within drawable.
``width`` | Width of region to render, in pixels, or -1 to use pixbuf width.
``height`` | Height of region to render, in pixels, or -1 to use pixbuf height.
``dither`` | Dithering mode for `GdkRGB`.
``x.dither`` | X offset for dither.
``y.dither`` | 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.

If GDK is built with the Sun mediaLib library, the gdk_draw_pixbuf function is accelerated using mediaLib, which provides hardware acceleration on Intel, AMD, and Sparc chipsets. If desired, mediaLib support can be turned off by setting the GDK_DISABLE_MEDIALIB environment variable. Since 2.2
