Hy list,<br>
I have a question. I'm doing a benchmarking test of a rotated map, and i get<br>
the result in the attached file.<br>
My question is why it take more time to draw a map rotated at 45° than a map<br>
rotated at 90° or 183° ???<br>
Thank you !<br>

It is not obvious to me why you are seeing the odd performance-base-on-angle<br>
results you are encountering. I implemented the rotation support, and the<br>
raster resampler used for warping rasters.<br>
