Thank you for your patience. OptiPNG plugin is working Just Fine. I'm trying to figure out how to set the "Date Taken" and "GPS Location" metadata for PNG. Looks like there isn't a standard, like EXIF for JPEG. I may open another forum question about that if I can't figure it out. Thanks again.

Is there a way to list the plugins that have been loaded or are being used? I've recently installed the OptiPNG plugin (copied the .exe & .dll into the FileTypes subdirectory) but I don't know how to tell it's actually being used. Also, does 64bit Paint.net require 64bit plugins? I'm using Windows 10 64bit and paint.net installs in "C:\Program Files" (not (x86)) but I can't tell if the OptiPNG plugin is 64bit or not (or if it matters). Ok.. My bad. It's easy to tell that this plugin has been loaded by the "Optimized PNG (*.png)" file type available during Save As. Other than that... is there a List Loaded Plugins option somewhere?

Is there a plugin that will allow me to create/edit exif tags on save?

JPG being a lossy format is why I was scanning to BMP then using Paint.net to save to JPG so I could edit the image without saving a lossy from a lossy. CanoScan Toolbox 4.6.1.2 only has BMP or JPG output support. I'll look into the PNG plugin. According to Exif Pilot the XResolution and YResolution exif tags are set by Paint.net as they're not present in the original JPG image saved by the scanner. The scanner -> JPG, re-saved by Paint.net -> JPG has "600/1" in both XResolution and YResolution exif tags The scanner -> BMP, Save As by Paint.net -> JPG has "299999/500" in both XResolution and YResolution exif tags. very odd.

I scanned a 3.5"x5" pic on a Canon 4200F at 600dpi and outputting as BMP using CanoScan Toolbox (4.6.1.2). I scan to BMP so I can open the image with Paint.net (4.0.9) and Save As JPEG and control the JPEG quality settings (which I can't figure out how to do with the Canon tool). Windows Explorer shows the Horizontal & Vertical Resolution of the original BMP as 600dpi and the JPEG as 599dpi. Any ideas why the JPEG image has reduced resolution? If I scan the pic and output it as JPEG, then use Paint.net to Save As (a different) JPEG, the dpi doesn't change from 600dpi. Even if I modify the image before Save As the dpi doesn't change. Is it normal for Paint.net to change the dpi?
