Hi,<br><br>I am performing two consecutive convolution operations, one after each other in a filter (the Gaussian Blur filter in the review board). Of course, I need a temporary buffer to do this. Below is what I'm doing.<br>
<br> KisPaintDeviceSP interm = new KisPaintDevice(*src);<br><br> KisConvolutionPainter horizPainter(interm, dstInfo.selection());<br> horizPainter.applyMatrix(kernelHoriz, src, srcTopLeft, srcTopLeft, size, BORDER_REPEAT);<br>
<br> KisConvolutionPainter verticalPainter(dst, dstInfo.selection());<br> verticalPainter.applyMatrix(kernelVertical, interm, srcTopLeft, dstTopLeft, size, BORDER_REPEAT);<br><br>The output I'm getting when I apply the rasterizing filter, is the result of the second convolution only. However, if I apply the filter as a filter layer, I get the combined result of both convolutions.<br>
<br>As boud suggested on IRC, I switched Krita to the old tile engine, and the results are correct in both cases. Therefore, the indication is that this is a problem with the new tile engine. Could anyone investigate further?<br>
