gdk:pixbuf-new-from-bytes (bytes colorspace has-alpha bits-per-sample width height rowstride)

bytes -- a g:bytes instance for the image data in 8-bit sample packed format
colorspace -- a gdk-pixbuf:colorspace value for the image
has-alpha -- a boolean whether the image should have transparency information
bits-per-sample -- an integer for number of bits per color sample
width -- an integer for the width of image in pixels, must be > 0
height -- an integer for the height of image in pixels, must be > 0
rowstride -- an integer for the distance in bytes between row starts

The newly created gdk-pixbuf:pixbuf object.

Creates a new pixbuf out of in-memory readonly image data. Currently only RGB images with 8 bits per sample are supported.
