mkidd Posted September 6, 2008 Share Posted September 6, 2008 When I try to load a certain PNG image in Paint.NET 3.36, I get the message "There was an error opening the file." without any further details. The image opens fine in Windows Picture and Fax Viewer (WPFV), Microsoft Office 2003 Picture Manager, IrfanView (4.10), Photoshop 5.5, and Matlab. The image file is about 1.4 MB, which exceeds the 256 KB limit imposed by the forum software, but I would be happy send it by other means. The only obviously peculiar thing about the file is that it has the exact same data on each image plane, i.e. it is a grayscale inefficiently stored in an RGB format. This PNG was created from a 24-bit TIFF file using WPFV. Paint.NET could not load the TIFF file either, although all the other applications cited above could. Curiously though, if I convert the TIFF to BMP using WPFV, Paint.NET can read the BMP file. And more bizarrely, I can load the PNG into Photoshop and save it again a new PNG file using the default PNG save options (Interface: None / Filter: Adaptive) and then read the resulting smaller (1099 KB) file into Paint.NET successfully. Other Photoshop save options, e.g. None/None or Adam7/Adaptive also yield PNG files that Paint.NET can read. Quote Link to comment Share on other sites More sharing options...
