ListView / ImageList transparency problem (I don't want transparency)

[zex2011]

I'm using TListView to display some thumbnails. The thumbnails are normal 128x128 jpg and png images, 24-bit true color. They are hosted in a TImageList.

The problem is that I cannot turn off transparency. Whichever pixel is in lower-left corner of the thumbnail will become transparent in ListView. When I open the editor of ImageList, the transparency boxes are disabled and there's now way of switching off this ugly "feature".

Does anyone know how to make ListView show images normally, without holes? The thumbnails are all 24-bit. Yeah, I tried with 32-bit as well, no change.

So, nobody has a clue how to solve this? Not even devs?

Not everybody responds immediately  Not knowing anything about image handling in Lazarus, I'm sorry I can't help you...

If you don't get a reply here, you can try the Lazarus mailing list.

Also, I assume you've searched the wiki and this forum without results...

Finally, it helps if you specify what Lazarus version and what operating system you're using.

Good luck,

As "ugly" fix you can always put some unused pixel in lower corner, maybe light purple is least used.
