How to set value of "Text Gamma" ?

[robertchen]

I am using Visual Basic 6 to develop a viewer application, but can not find the sample code to set value of "Text Gamma".
Please help.
Thanks a lot.

Hi, Robert.

You may use the one undocumented integer property:

Code: Select all

ax.SetProperty("PageDisplay.TextGamma", 1500, 0);

Values range is: [125, 8000], default value is: 1000. You should modify it before document opening.

Cheers.
