paint.net 4.2.1 is now available!

This is an important update that fixes many issues, including some crashes. It also adds JPEG XR file type support for Windows 8.1+.

If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. You can also force an update check by following these instructions.

For the Classic release, you should be offered the update automatically within the next week or so. You can get the updater soon by going to ⚙ Settings → Updates → Check Now. You can also download and install it directly from the website.

Change log:

  • New: JPEG XR file type support (Windows 8.1+ required)
  • Fixed: Holding Ctrl when dragging a selection with Move Selected Pixels will again leave a copy behind (but only with the mouse)
  • Fixed crashes when saving DDS images
  • Fixed VTF file type plugin. It was not working in 4.2 except for images that were an exact power-of-2 size on each dimension.
  • Fixed: .BMP files can be opened even if they’re not actually BMP images (they still need to be a valid WIC-supported file type such as PNG, JPEG, etc.)
  • Fixed very bad performance when opening large images with embedded rotation metadata
  • Fixed various crashes, such as when using File->New or Image->Resize, that sometimes happened if the previous update needed a reboot but either 1) it didn’t tell you that, or 2) it did but you didn’t reboot
  • Fixed the problem that was causing the need for the aforementioned reboot in the first place (string resources file was locked by the thumbnail provider shell extension)
  • Fixed: Text tool will no longer draw tiny text when an image uses dots-per-centimeter instead of dots-per-inch
  • Fixed menu ordering of effect plugins that have duplicate names
  • Fixed: The mouse wheel may now be used to scroll the Palettes menu in the Colors window (thanks @AndrewDavid for the suggestion and @toe_head2001 for the fix!)
  • Fixed metadata handling that was preventing some images with EXIF tag 330 from being able to load
  • Fixed metadata preservation for old images that pad EXIF string values with null terminators
  • Fixed title bar text color when using certain custom accent colors in Windows 10
  • Fixed title bar accent color when Tablet Mode is enabled

    Does the Free version of paint.net haver a ‘Chroma key’ for removing objects from 1 picture and pasting it into another picture? Or using a tool like magic lasso to select the image then paint over it with a brush to finish selecting it then cut and paste it into another image without drawing every little detail. If it does where do I find it? For Windows 10

    Hi,

    Excellent software, but one thing is really missing. Expand/shrink selection. This would be one of the purposes:
    1. You have an image of a cellphone on a green table. To select just the phone, click on the green table with the Magic Wand too. That creates a selection.
    2. But the selection is not really perfect. To make it more perfect I would expand the selection by 1 pixel (or maybe expand and then contract by 1 pixel). That would smooth out the selection and/or get slightly into the object, which is sometimes desirable.

    Currently there’s no way to change the selection, except by manually doing it. Do you think the algorithm to slightly expand/contract a selection would be too complicated?

    Best regards,

    Zelko

    Hello,

    Amazing software. But there’s one thing really missing: Expand/contract the selection. It’s absolutely essential when extracting a sprite from a photo, or using a Magic Wand tool.

    Magic Wand is amazing, as it speeds things up significantly, but it creates lots of noise around the edges. An option to Expand/Contract the selection by 1 pixel (or more) removes this noise. Also, it can shrink the selection to avoid unwanted artifacts.

    I assume that contracting a selection is probably not easy. The algorithm must be pretty weird. But the Magic Wand tool is not very useful without that option. That’s why I’m nagging you 🙂

    Thank you for the great app! Cheers!

    Zelko
