I don't have any issues with either getPixelsWithLength and savev.
for the savev call there is an missing \ just before test.jpg, but
that might be a copy and paste error?
For the options that are available for savev the documentation of
GDK-PixBuff lists the few available options.

Although i'm on Linux so that might make an difference.
Ups, that was my fault, sry :(
But how do i get now the color for each pixel out of the ubyte[]?
It looks like the array has the R, G and B values like this:
[R, G, B, R, G, B, R, G, B, R, G, B, .......]
for every pixel from left to right top to bottom,
So data[0] gives you the Red value for the pixel at 0,0.
data[1] the Blue value and data[2] the green value.
data[3] would then be Red for pixel 1,0.
