well, I think the main problem of understanding is in function
MapContext.<b>getExtentFromFullExtentAndImageSize</b>() ... I think
the new height etc are calculated there? <br>

<br>
<br>
I have tried to load a raster image (had to try jpg, because *.png
did not even load), but I am getting a wrong position of the
extent. Anybody got the same error?
<br>
<br>
I have tried the debug mode, but there are too many functions to
catch on. Perhaps anybody can help?
<br>
<br>
Somewhere the map origin is changed from the upper edge to the
lower edge, that far I could follow, but then the image extent
(height) and the origin coords (of Y) has been changed. Why? it
seems to be very hard to understand the whole way of building the
image at the right place.
<br>
<br>
However, in attachment the original rectangle and the changed one
are shown with their values while debugging...
<br>
<br>
The lower edge of the final image is positioned between those Y
values (@ 53.464) but it needs to be positioned at 53.475....
<br>
<br>
what is getRasterTansformation() actually doing?
<br>
<br>
<br>
Thanks in advance, if anybody can help. However, that issue should
be fixed, I think. The import of PNG is not even possible, as I
mentioned before..
<br>
<br>
Regards
<br>
