I'm developing a plug-in for Adobe Acrobat Pro.
I want to change the overprint-preview setting by the Acrobat plug-in.
The trouble is that the plug-in can not change the overprint-preview setting of Acrobat.
I tried the following code, the overprint-preview setting was not changed of Acrobat.
AVAppSetPreference(avpShowOverprint, (void *)true);
What is not enough for changing the overprint-preview setting?
Please tell me know if there are any necessary processing.
