I have installed Imaging 0.24.2 in a recent Lazarus from svn (rev 14810) under Windows.
When i load a bitmap file into a image list using the image list editor the transparency does not work even if i load the project in a machine where vampyre is not installed.
If i comment RegisterTypes in ImagingComponents unit and rebuild Lazarus the transparency works again.
To a test application and more info see the bug report at http://bugs.freepascal.org/view.php?id=11150
I'll look into it when I have some time, thanks for letting me know.
is this the same problem i am getting, where lazarus image editor puts unwanted black backgrounds on all my images? good job someone is on the case.
