pierrotsc	Posted - Sep 10 2019 : 12:38:39 Not sure if i am doing that correctly. I am using the scanning demo. When i have the scanner dialog showing up, i can pick the resolution i want to scan with. If i do not use the scanner dialog, i have the automatic acquire set at 300 dpi. That is perfect. now if i use the scanner dialog and pick 200 dpi, i guess the imagenmview has a 200 dpi thumbnail. How can i set a warning that the image scanned should be 300 ? Is that possible. Best

xequte	Posted - Sep 15 2019 : 17:37:47 Oh, sorry, I misunderstood. The scanning DPI should be applied to the image DPI, so, for example, the DPI of the first image would be: ImageEnMView1.MIO.Params[ 0 ].Dpi https://www.imageen.com/help/TIOParams.Dpi.html Nigel Xequte Software www.imageen.com
pierrotsc	Posted - Sep 12 2019 : 11:42:35 Nope, i scan with the dialog at 360. i click on the image in imagenmview and it shows 300 and not 360. I wonder why. Advice ? ShowMessage(FloatToStr(ImageEnMView1.MIO.AcquireParams.XResolution));
pierrotsc	Posted - Sep 12 2019 : 10:56:41 Never mind. i reread your message and i think i got it. Appreciate it Best
pierrotsc	Posted - Sep 12 2019 : 08:56:34 Nigel, let me try to re explain. When i use the demo and i acquire using the showdialog, i get a thumbnail in the imagennmview component. Now when i select this image by clicking on it, i would like a dialog to pop up to show the resolution it was scanned. Is that possible ? Thanks
xequte	Posted - Sep 11 2019 : 21:51:22 Sorry, I may be misunderstanding your requirements. You can get/set the DPI using ImageEnMView.MIO.AcquireParams.XResolution: https://www.imageen.com/help/TIEAcquireParams.XResolution.html Nigel Xequte Software www.imageen.com
pierrotsc	Posted - Sep 11 2019 : 20:59:12 thank you. i just wanted to know if it would be possible for you select the imageenmview to find out the dpi but it looks like imageenmview does not do that.
xequte	Posted - Sep 11 2019 : 16:26:16 Hi If you are acquiring with the scanner's dialog, then it is not possible to show a warning message (after the dialog), because the whole transaction is handled by the Twain driver. Nigel Xequte Software www.imageen.com
