Bitmap images are converted in Image mask

Hello all,

I have a pdf with Bitmap images.

I convert the pdf to postscript file (to be used with the distiller 8.1.2) and the new pdf file (created with the distiller) has Image mask in place of Bitmap image.

Do you know why Adobe 8.1.2 (and older) converts the Bitmap image to Image mask? Or a setting to prevent the conversion.

My problem is that when I have big file with Image mask, Adobe leaks memory and the file is not correctly created (the last pages are blank).

In the postscript file there is the operator "/O 1" which convert the image to Image mask. When I replace the operator "/O 1" with the operator "/O 2", I have a normal image...

Kind regards,

Joël

Hi Joel,

I cannot specifically answer your question about the memory leak and make a mask as such but do pose a question to you - why are you re-frying an intelligent PDF back to an ancient page description language and then re-generating the PDF again?

There is surely an easier way to process your information without jumping throug hoops?

Best regards,

Jon

Hi Jon,

I need to create a new postscript to add a watermak with the Normalizer Server and sometimes add some new settings for the document (new settings which are used with the Normalizer). The Normalizer is more customizable than the Distiller.

Joel
