gorchi	Posted - Mar 23 2012 : 03:21:41 Hi, one question regarding loading DICOM files. Is there a setting that would enable some equalization (auto brightness or something like this) so that after loading some DICOM's the image would not look too dark or to bright? Comparing the same Dicom in IrfanView, the image there looks much much better than in the demo (Dicom viewer) just downloaded from Your site... Regards, Goran

gorchi	Posted - Mar 26 2012 : 03:48:54 Thank You Fabrizio! I sent Nigel one such "dark DICOM" in e-mail in september 2011 and since I can't afford testing the new IE I've tested these dicom's using demo DICOM viewer. Unfortunately there is no difference between my current version 3.11 and 4.1 :( Also the idea in 3.11 does not work either. I'll try to find some computer where I can try Your suggestion in the next days.

gorchi	Posted - Mar 23 2012 : 03:44:20 Thank You Fabrizio! StretchValues is new to ImageEn 4?
fab	Posted - Mar 23 2012 : 03:37:42 Hi, you should call AutoCalcBWValues() (which automatically adjusts TIEBitmap.WhiteValue and BlackValue), and StretchValues() to make then changes permanent. Example: ImageEnView1.IEBitmap.AutoCalcBWValues(); ImageEnView1.IEBitmap.StretchValues(); ImageEnView1.Update();
