Dear Melk,

I've worked around the problem using a different method.
See the headlines following :
- create a new image using gflAllockBitmapEx with the desired dimension
- for each image to merge, copy pixel per pixel all pixels coming from the source image to the destination image at the right ...

Dear all,

My objective is to use gflMerge image to create a mosaic of images of different size placed at precomputed position in the mosaic.
For the test below, I don't take this constraint into consideration.

Nature and type of the images are always the same.

Please find my code hereinafter ...

Dear Melk,

Thank you for your feedback.
On my side, I didn't point out any solution.
Images with alpha channel causes allocation error with gflMerge.
In addition, I've tested several image order/combination and it delivers the same result -> first image dimension and data for the merged image ...
