<DIV><FONT face="Times New Roman" color=#000000 size=3>Hello,</FONT></DIV>
<DIV>that method computes the extent of the view when you add the first layer. The app knows the size of the screen and the extent of the layer, and their ratios are different, so you have to do a simple computation to find out the extent of the new view.</DIV>
<DIV> </DIV>
<DIV>Maybe you have misunderstood the extent of a layer and the extent of the view?</DIV>
<DIV> </DIV>
<DIV>When you add the first layer, the extent of the view is the smallest rectangle which contains the extent of the layer and, at the same time, respects the width/height ratio of the screen, of course.</DIV>

<DIV>Regards,</DIV>

<DIV>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>Am 29.03.2011 21:00, schrieb Marcel Schoolmeesters:
<BLOCKQUOTE>Hello, <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.

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.

However, that issue should be fixed, I think. The import of PNG is not even possible, as I mentioned before.. <BR><BR>Regards <BR><BR>Marcel <BR><PRE><FIELDSET class=mimeAttachmentHeader></FIELDSET>
