I have recompiled my old 32bit app into 64bit and have discovered that the ImageEnView1.Proc.SetTransparentColors() method does not seem to work anymore. I have made no other changes to the surrounding code and I have version 9.2.5 installed for both 32 & 64 bit versions.

Is there something extra I need to do in 64bit?

Thanks, I will have to install the update.

Hi David

It looks like an issue in 9.2.5. Your compiled EXE fails, but when I compile with 9.3.0 it works as expected.

Hi Nigel, sorry for the delay, busy weekend...
I have made a test app in both 32 & 64bit which shows the problem (my main app is a large commercial app). You can download the apps & source code from this link: https://we.tl/t-7k1fIL9wKp
Just run the app, open an image (sample included). click on a point in the image to set the transparent color. Save it and view the resulting PNG. The 32bit version has the transparent color, the 64bit does not.
David.

Hi

So you are running the ImageEn code inside a DLL? Does it also fail for you in a normal EXE? Please include an image and the code you are using to reproduce.
