graph_man	Posted - May 05 2017 : 06:22:10 Latest version of the command currently removes inclined lines. Please fix this issue and remove only FULLY isolated pixels (by sides and corners). Currently you remove also pixels contacted by corners.

xequte	Posted - May 10 2017 : 21:43:32 The update should fix this. Nigel Xequte Software www.xequte.com nigel@xequte.com
graph_man	Posted - May 10 2017 : 14:42:20 Could you fix this issue to delete only isolated pixels (all sides and corners)? See previous image.
xequte	Posted - May 09 2017 : 22:53:47 Hi We have an update available where you can exclude diagonal pixels with RemoveIsolatedPixels. You can email me for the source. Nigel Xequte Software www.xequte.com nigel@xequte.com

graph_man	Posted - May 08 2017 : 20:04:34 1. My main question was about RemoveIsolatedPixels. Currently it removes NOT ISOLATED pixels. RemoveIsolatedPixels(1, Black) removes the entire line in my example. Is it OK? 2. RemoveNoise(1) removes the entire line in my example. Is it OK?
xequte	Posted - May 08 2017 : 19:57:12 Hi We cannot find any change in functionality in 7.0.0 that would affect this image. If you set correct parameters then RemoveNoise will work as expected (in this case just set "invert" to true). Here is a test that adds random noise to the test image, and then tries to remove it: imageenview1.io.loadfromfile('test_bug.tif'); for i := 1 to 10 do imageenview1.IEBitmap.Pixels_ie1g[random(imageenview1.iebitmap.width), random(imageenview1.iebitmap.height)]:=false; imageenview1.update; imageenview1.Proc.RemoveNoise(8, true); Nigel Xequte Software www.xequte.com nigel@xequte.com
xequte	Posted - May 08 2017 : 02:01:10 Thanks, we will investigate. Nigel Xequte Software www.xequte.com nigel@xequte.com

xequte	Posted - May 07 2017 : 19:22:38 Hi Please forward your test images. Nigel Xequte Software www.xequte.com nigel@xequte.com
graph_man	Posted - May 05 2017 : 06:45:15 Also I see this issue at using "RemoveNoise" command In previous version "RemoveNoise" worked without issue.
