Requested Add support for HDR, 10/12bit, alpha transparency

[insectinegate]

I'm quite disappointed that the development of IrfanView in terms of satisfying user needs in 2023 has all but ceased.

IrfanView does not support:

• HDR images
• 10/12/16 bit per channel images and images using non-RGB encoding such as YUV
• Alpha transparent images

Even if you open the said images, they will be converted to 8bit per channel [representation].

If you convert or save these images, all these features will be lost. Data will be lost.

Please upgrade IrfanView to incorporate all these features. The program is stuck in the late 90s in terms of supporting image data. This is a little bit sad to see.

Lastly, I'm quite miffed that even though IrfanView now has a JPEG-XL (JXL) plugin, you cannot use it to losslessly compress JPEGs.

I would like to see support for more color depth. I guess passing through additional bits wouldn't be too difficult. Perhaps all effects that can't be upgraded to handle higher bit depths could be disabled just like it was in Photoshop 7.0 where you could only do basic operations in Mode > 16-bit.

Transcoding between varieties of JPEG formats belongs in a special tool, for example, in Lossless JPEG Operations. A normal open>save should not handle this case because you always save from uncompressed format after at least some minimal editing.

That's weird as these forums are linked from the main website. OK, I'll email him.

Not at all. Irfan Skiljan is the sole developer, there are millions of users.
He could not possibly provide support to all of them. Often, someone here can answer to save time for users and Irfan Skiljan.
