Hello

I have a PNG with iTXt chunk containing XMP information.
The app compiled in x64 mode with ielib64.dll can access it via PNG_TextEntries, but in x32 mode with ielib32.dll - have not...

What am I doing wrong?

Thank you! It's works.

Hi Andrew

It looks like this kind of PNG text field is only supported by ielib, not the native PNG code (we'll look into that).

To have it work with ielib32.dll you need to ensure you have enabled:

{$define IEUSEDLLPNGLIB}

in ie.inc

with TImageEnIO.Create(nil) do
try
  LoadFromFile('C:\5C4C7280-E3CA-4042-801A-68A2C3342C8B.PNG');
  ShowMessage(Params.PNG_TextKeys.Text);
finally
  Free;
end;
