The Surface class does not require locking and unlocking the image data.

The preset options attempt to tune the WebP encoder settings for the specified type of content, the details of the changes are not documented.

Release version 1.1.25. Changes: Updated AOM to version 3.6.1. Added a check box for lossless compression. This replaces the previous behavior of silently using lossless compression when the quality value is 100.

No there is not. From the FAQ:

The DDSFileTypePlus version in your release notes should be 1.11.8.0.

The PSD plugin developer lists their email address on the PSD plugin site: https://www.psdplugin.com/

My RAW FileType plugin should support those files. The PowerShot S95 is listed as one of the cameras that LibRaw supports.

You will need to upgrade your OS to Windows 10 (or 11). The forum rule require everyone to be using the latest version of Paint.NET. See https://forums.getpaint.net/topic/2932-read-first-the-rules-yes-you-read-this-2013-12-21/#7

Release version 1.3.17. Changes: Disable the quality slider when using lossless compression. Lossless compression will always use a quality value of 100. Added a few optimizations to the EXIF parsing code.

Release version 1.5.1. Changes: Improved the UI responsiveness when changing settings.

Release version 3.2.4. Changes: Updated G'MIC to version 3.2.4.

No it is not. I had to modify the PDN file loading code to read the image. I made the /ignoreCorruptPDNChunks command ignore any corrupted chunks that are filled entirely with zeros. I submitted those changes to @Rick Brewster for inclusion in the next version of PDN.

That sounds like a bug in that version of Linux. The BMP format specification allows biSizeImage to be 0 when biCompression is BI_RGB, see https://learn.microsoft.com/en-us/windows/win32/api/wingdi/ns-wingdi-bitmapinfoheader. Paint.NET uses the BMP read/write functionality that is built-in to Windows (Windows Imaging Component).

The file is partially corrupt. Only 297 of 367 chunks are valid, and the rest of the file is filled with zeros. That command does not handle this form of file corruption in version 5.0.3. I managed to recover part of the image and save it to a new PDN file: https://www.dropbox.com/s/6692phe4qddntnw/LargeMapUkr-2-recovered.zip?dl=1

That error occurs when loading a PSD file. The PSD format can use ZIP compression when saving the image data.

You may need to delete old attachments to free up space, the forum limits the total attachment size for each user. Images should normally be hosted on an external site.

You can zip the file and upload it to DropBox, Google Drive etc and post a link to the file. If the zipped file is small enough it can be attached to a forum post. You should also remove the email address from your post, that will just invite more spam.

Release version 3.2.3. Changes: Updated G'MIC to version 3.2.3. Show a modal dialog in Paint.NET when the plugin is running.

Paint.NET does not currently have a channels palette or mask layers, hopefully these features will be added in the future. As a workaround for manipulating the alpha channel you can use the Switch Alpha to Gray and Apply Alpha Mask plugins from @BoltBait's plugin pack.

The paint.net image text is set by Windows. It indicates that paint.net is configured as your default program for opening .jpg files, but those files can still be opened by other programs.

When lossless compression is enabled the quality slider controls the compression speed, larger values produce a smaller file.

What about using Ctrl + Shift + Drag, or would that conflict with some existing behavior.

Yes.

Yes.

Release version 3.2.2. This release is for Paint.NET 5.0+ Changes: Updated G'MIC to version 3.2.2. Fixed a crash when running as a repeat effect.
