xequte	Posted - Nov 10 2015 : 15:09:35 Hi In our analysis ImageEn correctly displays this image, which contains an invisible range of values. To show the image you should adjust the visible range using TImageEnView.IEBitmap.BlackValue and WhiteValue. This is done automatically if you call AutoCalcBWValues(): imageenview1.LegacyBitmap := false; imageenview1.IO.NativePixelFormat := true; imageenview1.io.loadfromfile('00000001.TIF'); imageenview1.IEBitmap.AutoCalcBWValues; Nigel Xequte Software www.xequte.com nigel@xequte.com
klausdoege	Posted - Oct 29 2015 : 05:34:41 Hello Carlo, you can use my Tool "DigiFoto" to read or work with picture. It's how photoshop but freeware. http://www.klausdoege.de/DigiFoto/ Klaus www.klausdoege.de
carlonarcisi	Posted - Oct 29 2015 : 05:10:29 Klaus ! thanks for your time ! Nigel has already given me the bad news ... The images I'm trying to open a 16-bit TIFF are used in the medical environment. At the time apart from the program written in java (ImageJ) , I can read the image TIFF 16Bit with a demo of LeadTools .. But I'm not going to buy LeadTools ! Thanks a lot carlo
klausdoege	Posted - Oct 29 2015 : 04:47:56 Here is your first image, open with Imageen and save with imageen. I take my own prgram "DigiFoto" But you must change the white value see histogram. Your picture has only value's between 0..18 The color value's from 20 to 255 are = 0(black) I have set the white value on 20 and you can see the result in the attached file. attach/klausdoege/201510294477_00000001x.zip 103.74 KB Klaus www.klausdoege.de
