I've got error when opening dds file, exception message below:

I am using Paint.NET to edit and save DDS textures. I have noticed that Paint.NET with this plugin saves textures in a worse quality than other tools. For example, on a very old X-Ray SDK (S.T.A.L.K.E.R.), texture quality is better.

Sorry for my English (I write through a translator).

I tried to save PNG image having transparent pixels into different BC formats and found that the image in BC1 format becomes sharper (see test_bc1a.dds).

Compare the following DDS files between themselves and the original image.

dds.zip

BC2, BC3 and BC7 formats support alpha channel so the original image is converted fine.
But even images in BC4 and BC5 formats that don't support transparency are still similar to the original one.
Also after adding to the original image opaque layer in Paint.NET I saved it in BC1 format to show how I expected it supposed to look like.

Can remove DDS"2" stuff, as well as talk about how the plugin is now bundled with the app, and how you can still install it and have it override the built-in bundled version of the plugin as long as it's a newer version.

Hello! I have a similar problem with textures from the game STALKER SHoC.

Exception:

System.FormatException: The DDS file is invalid.

These textures are displayed in the game and opened in Photoshop:

FileTypeOptions.SupportsCancellation, which adds the possibility of OperationCanceledExceptions being thrown from both the Stream and ProgressEventHandler, would make the user experience better. Happy to implement this myself if you'd like.

.dds2 is no longer necessary. So, maybe remove it :) The app will still allow .dds2 if the user has installed the plugin, but only if the user's plugin version is newer than the bundled plugin's version. I can change that policy if needed, but since we'd both like to get rid of .dds2 this is what I've done for now.

When encoding larger images with the WARP DirectCompute device the Paint.NET UI stops responding when the progress reaches a certain point.
WARP batches its rendering calls, and after it starts rendering the SaveConfigDialog will freeze if you try to interact with it.

Edit: The UI freeze occurs regardless of whether D3D11_CREATE_DEVICE_PREVENT_INTERNAL_THREADING_OPTIMIZATIONS is set, so I am not sure what could be causing it.

I observed the SaveConfigDialog being marked as not responding in task manager when using a 4096x4096 pixel blank canvas.
On a 1024x1024 pixel blank canvas the SaveConfigDialog does not fully paint until the image has been compressed, it is not blocked long enough on my system to show up as not responding in task manager.

Unfortunately, the DirectXTex CPU encoder for BC7 is extremely slow so it is not a viable alternative when compressing large images.

Would you be willing to add support for files made with DirectXTex?

In PDN 4.2, I added Super Sampling back to Image->Resize and some other places, and changed any default values away from Fant. It would therefore be consistent if DdsFileTypePlus defaulted to Super Sampling.

I can't get texture to load in game, I don't know what file type to save as to get it to read. Only option is to save as every single one and try all combinations of error metric, mip maps, and what not.

I feel like for overwriting it should default "save configuration" settings to the files originals

Couple of issues found ...

1. When saving one of the new format DDS .. Say BC7

The file is given a filename like name.dds2

Which is sort of ok, if you rename it to .dds then the target game will recognise it for the type of dds it is anyway - Would just be better if we did not have to rename it and it used the .dds extension as normal.

Note Intel Texture Works plugin for Adobe Photoshop does not have this problem, a BC7 dds file with the normal .dds file extension loads just fine into Adobe Photoshop, just like they do with a game engine that supports them (Skyrim Special Edition / Fallout 4).

Also, when loading the same texture back into Paint.Net, if the file is now named .dds, PDN will try to load it but fails to recognise the file, even though it was made with PDN - Solution = rename it name.dds2

Then PDN will recognise and load it correctly O_o, bizarre state of affairs.

Can you fix this behaviour please.

2. In accordance with Intel Texture Works plugin save dialogue we are supposed to be able to save a BC7 as Linear Fine (second BC7 option in the linked screenshot)

But in the save dialogue for dds2 implemented in PDN there is no such option that seems to stick to the same naming convention

Which of your options equates to ..

BC7 8bpp Fine (Linear, DX11+)

And if you do actually support the same option, could it be made to read as BC7 Fine Linear in accordance with the Intel Texture Works dialogue screenshot, so that we are all singing off the same hymn sheet and know for certain the format saved is the format desired.

I think it'd be useful for people to know where the DDS plugin comes from and who the author is, and that they can install a newer version if they need to (probably need to add instructions to the plugin's forum post?).

You can add a clickable link by using a UriProperty in the PropertyCollection.
