<DIV><FONT face="Times New Roman" color=#000000 size=3>Hello, Stefano, thanks for reporting this bug.</FONT></DIV>
<DIV> </DIV>
<DIV>I think the problem is that in the method getAllLayersExtent in the class MapContext, we are modifying the extent of the layer while computing the union of the layer extents</DIV>

<P><FONT size=2>Hi, I'm experimenting this behavior with raster layers with external .wld<BR>file ('WKFRasterDriver', I assume). See attached file for some data.<BR><BR>- Startup a new project with EPSG: 32633<BR>- Load 'big_extent.shp'<BR>- Load 'north.gif'<BR>- Do some "zoom in", "zoom out", "zoom extent"; all is ok<BR>- Go in 'Layer Properties' and invert the display order of the layers (now<BR>'big_extent.shp' is above 'north.gif')<BR>- Do 'zoom extent' and the raster layer is wrongly transformed to the<BR>maximum extent<BR><BR>Another:<BR>- Startup a new project with EPSG: 32633<BR>- Load 'south.gif'<BR>- Load 'north.gif'<BR>- Do some "zoom in", "zoom out", "zoom rectangle"; all is ok<BR>- Do 'zoom extent' and the raster 'south.gif' is wrongly positioned below<BR>'north.gif'<BR><BR>Perhaps a bug in the driver assuming an incorrect affine transformation (it<BR>seems that the parameters of the affine transformation are not changed but<BR>maintained between one layer to another)?<BR><BR>Thank you in advance for your help!<BR><BR>Stefano<BR></FONT></P></DIV></BODY></HTML>
