Thanks,

I'll try to repay the favor to someone else with a question I can answer.

 Paulo,

 Thank you for your response, but I must just not be getting it.

 Do you have any code samples, other than the tutorial, that illustrate
image
 masking and transparency?

 Thanks

 The pdf format doesn't support ARGB, only RGB. Transparency is done:

 - setting an array to mark the transparent colors (6 elements for RGB)
 - creating a BW image to use as a mask
 - creating a grayscale image to use as an smask to have 256 degrees of
alpha

 Paulo Soares

  I have a dynamically generated ARGB Image that has some transparent

RE: [iText-questions] Transparant Images

2004-06-14 Thread Bill Ensley 
MY FOOLISHNESS!!!

I have untold hours into learning transparency, and it was all
foiled by the fact that I was using an old version of ACROBAT!!!

I tested this class below and it did not work in Acrobat 4.0,
But it works perfectly in Acrobat 5.0 and higher.

I did not think until now that was my problem.

Thank you all for your valuable input.
