RGtk2 (version 2.20.31)

gdkDrawRgb32Image: gdkDrawRgb32Image

Description

Draws a padded RGB image in the drawable. The image is stored as one pixel per 32-bit word. It is laid out as a red byte, a green byte, a blue byte, and a padding byte.

Usage

gdkDrawRgb32Image(object, gc, x, y, width, height, dith, buf)

Arguments

object
The GdkDrawable to draw in (usually a GdkWindow).
gc
The graphics context.
x
The x coordinate of the top-left corner in the drawable.
y
The y coordinate of the top-left corner in the drawable.
width
The width of the rectangle to be drawn.
height
The height of the rectangle to be drawn.
dith
A GdkRgbDither value, selecting the desired dither mode.
buf
The pixel data, represented as padded 32-bit data.

Details

It's unlikely that this function will give significant performance gains in practice. In my experience, the performance gain from having pixels aligned to 32-bit boundaries is cancelled out by the increased memory bandwidth.
