I have two monitors. The main one (4k, landscape) has 175% zoom applied to it in Windows monitor resolution settings. The secondary one (Full HD, portrait) has no zoom applied to it (that is, 100%). Monitor 1 config in Windows. Monitor 2 config in Windows. In such setup, Paint.NET viewport (canvas) does not use 1 pixel to display 1 pixel. As you can see in the image below, the viewport is much smaller than the window, even with the canvas resolution equal to the screen resolution (1200x1920). You can see that Paint.NET zoom is 100%. Problem: Paint.NET canvas smaller than it should be. Zoom problems wouldn't be unexpected in Monitor 1, which has 175% zoom as I said before. However, this is in Monitor 2, which does not have zoom/scaling applied. As such, it is impossible to use Paint.NET accurately in Monitor 2. More information: Analyzing the attached image, it's easy to see that Paint.NET is using 686 pixels to represent the width of 1200 pixels. That is, 1.75 times less, which matches the zoom level of Monitor 1 (175%). In Monitor 1, everything works fine. That is, one pixel is displayed in one pixel when Paint.NET zoom is 100% (again, Windows monitor zoom is set to 175%). What was expected: that Paint.NET canvas would always use 1 pixel to represent 1 image pixel, regardless of Windows monitor zoom.

Paint.NET 4.0.1. Here's exactly what I did: Open original.jpg Save as flat.bmp Save as flat.jpg Here I discovered that flat.jpg still had EXIF. Now, without closing Paint.NET nor flat.jpg (or doing anything else in it, for that matter): Open flat.bmp Save as flat.jpg Here I checked that flat.jpg didn't have EXIF anymore. Yeah, that's what I figured. However, I expected that, once I saved the .jpg as .bmp, it would be as if I had closed the .jpg and just opened the .bmp. Scratching all the previous context, that is. Don't you agree that's a fair expectation? Regards.

I needed to remove EXIF rotation data from a photo I took with my phone, so I fired up paint.net and proceeded to open the .jpg, save it as .bmp and then save it again as .jpg. To my surprise, the data was still there. generated by http://regex.info/exif.cgi However, when I tried opening the .bmp from scratch and saving as .jpg, it worked as intended, i.e the new .jpg had almost no EXIF. I'm pretty sure paint.net shouldn't have kept the EXIF through the .bmp. Am I wrong in that?
