Hi, Thanks for the video. I also could reroduce the problem. I reduced the test to its minimum by setting -Xmx100M and trying to load the hillshade tif alone. Surprinsingly, the problem occurs when used memory is about half of the available memory. By chance, I found some code in RasterImageLayer which test when 50% of the available memory is used, and managed to eliminate the black and white strip effect by removing the test line 390 if(needFreeRAM == false). But honestly, this is a part of the code I'm not familiar with, and it will take some more time if I want to understand why this code change eliminate the visual effect and to check if it has unwanted side effects. The code seems to be from Stefan, and modified by bertazza. If someone wants to take the challenge (and explain to me), he's welcome. Otherwise, I'll try to study the code and propose a fix within a few days.

objet : Re: [JPP-Devel] elevation raster and commons imaging
After Roberto's video I was able to reproduce the bug. I had to load 39 (!) raster layers together the huge shapefiles (I used the same rasters that Roberto kindly provided) before I had that spagetti shape raster our. I have no idea about the reason of it. I can image it could be related to the delay between the time the Raster is loaded and the time it is completely drawn in the view. More files are loaded, more memory is engaged, more time it takes to drive display a file.

hey Roberto, this seems to fall through the cracks ;(. please try and report on the following when you find the time > additionally please try your routine with r6564+ but instead of Sextante image use the "Open->File->(Select your tifs, click Next)->(keep Use same settings for *.tif enabled, Select *Buffered Image (Commons Imaging)*, Click Finished). this merely is a rendering test, raster tools will not work on it. please comment on speed, memory usage and overall performance incl. bugs. thx.. ede _______________________________________________ Jump-pilot-devel mailing list Jump-pilot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel
