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
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.
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.
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
