Trouble with high dpi display settings


I am running 1680x1050 on my laptop (Dell E1505). The maximum size I can make the Cropper form expand to is 1224x720. In addition, when I take a screen shot with Cropper it is shifted. See attached sample images. One taken with Cropper and the other in the exact same position but using OneNote 2007 Screen Clipping pasted into Paint.NET and saved as an image. Also, as you can tell from the two captures, while the Cropper tool indicates that I have a 320x240 rectangle selected, it is actually about 400x300 according to the size of my OneNote clipping. However, the misaligned Cropper capture is 320x240, just shifted.
Brian - 120 dpi setting causes the problem. Updated title to reflect the cause of the issue.

Thanks Patrick. I'll look into it. I don't think I have anything that will run at that resolution right now though. I'll look around ans see what I can do.

Also, the text in the window looked larger, did you change your text dpi?

I'd be happy to help track down the problem and debug a solution on my wide screen resolution... You going to put the code back up in source control? If so, let me know how you'd like to receive the patch...

by the way here is a sample screen shot of what is happening on a widescreen snap:http://s3.amazonaws.com/paltman.com/images/9062e09e-e81a-43dc-95e6-40c0c1abda86.png

So i finally did what you recommended and checked the dpi settings...


Much better now... Was set to 120dpi, brought it down to 96dpi...

I was thinking it was a 120 dpi problem. I need to make Cropper dpi aware eventually. Thanks for checking it out.

Love it, except if forces me to use 100% (default) display size setting (Windows 7); when 125% (medium) or 150% (Large) is set, the image captured is not what was selected. Can the program be modified or an option be added to correct for this?

Sounds like a very interesting problem to solve. I'll give it a shot and let you know.

I also just experienced this problem. Definitely a DPI issue. I'm running 150% on my Surface, and it has an weird shift and scale bug, similar to what Brian originally reported. On my laptop running at 100%, I have no issues.
