Hi,
I'm converting html to ps, but it produces a solid white background color. how should I change the ps file so the page background will be transparent after converted to image?

It depends on how the application generating the PostScript job implements the white background.

If you could supply a sample file, I possibly could give you some hints .

Hi,
Thank you for the reply.

The sample file can be retrieved on <http://adbuilderdev.falconocp.com/companyname.ps>

It has solid white background, and I need to change the background to transparent.

Thanks again for the help...

The line that is putting the white background is :

	612 792 false pdfSetup

If you can either delete this line or comment it out that will make the
background transparent.

Note that the "Company name line has a white background that continues
to the right side of the page.

In the case of this sample file, the white background is generated by the statements (the comments beginning with a percent sign added by me):

[1 1 1] sc % set red, green, and blue to maximum, i.e. white

0 0 800 47 re % define a rectangle that describes the area

f % fill the rectangle with the defined color

Note that the instructions like "sc" etc. are defined in the prologue section of the file.

And the file looks like generated by (or by a descendant of) the xpdf suite from a PDF file. Therefore the possibility of an algorithmic solution for stuff like this seems rather unlikeky
