gdkPixbufRenderToDrawableAlpha: gdkPixbufRenderToDrawableAlpha

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 gdk_drawable_set_colormap. WARNING: gdk_pixbuf_render_to_drawable_alpha is deprecated and should not be used in newly-written code. This function is obsolete. Use gdkDrawPixbuf instead.

Usage

gdkPixbufRenderToDrawableAlpha(object, drawable, src.x = 0, src.y = 0, dest.x, dest.y, width = -1, height = -1, alpha.mode = NULL, alpha.threshold = NULL, dither = "GDK_RGB_DITHER_NORMAL", x.dither = 0, y.dither = 0)

Details

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