fill region with color?

[msc0tt]

I use Acrobat for minor adjustments to PDFs, but clearly it is not intended to be an editor.
I receive PDF graphs which are basically black lines on a white background. What I need to do is fill in defined regions of the graph with different colors, and save the result back to PDF. I've tried CorelDraw, but it didn't work because the lines defining my region are not all the same "object", and the color filled the whole page. I tried converting to bit map also: the 'fill region' now worked but I lost the sharp definition of the lines and fonts -no good.
What I seek is a 'paint program' that speaks PDF and can paint a region that is 'visually' enclosed. I'm currently seaching planetpdf but nothing has jumped out.
-with thanks,
Mike

I am not sure what you mean by region. BUT If you want to change colors in Acrobat. You can use Pitstop a Acrobat add on, it is for doing prepress work on your PDFs for production. One feature is global change, this allows you to change the colors in your pdf. You can select one bar for example that is black and do a selection change only. The globel change has options to mix your colors based on CMYK or RGB. So there for you can set one bar to 20% and 60% cyan for darker blue.

I hope this is a long the line of what it is you need to do. If this does not help sorry for the bad info..

I just tried Photoshop Elements, and it mangled the document. I'm trying to find an experienced colleague with access to the other Adobe editing apps. I'll try to explain the "region". Picture a standard sine wave curve extending the width of my page. Now, picture a straight horizontal line running right through the middle. Visually, we've got a bunch of half-spheres on the page. I think of each of these half-spheres as a region, since it is fully enclosed within a black line. The problem is that my image consists of two 'objects': the wiggly sine wave, and the horizontal line. The tools I've tried so far only fill in an object, NOT a "visuallt enclosed region". This is when I converted to bitmap. NOW, the fill-region tool works as expected but the resulting image now looks like crap since I lost my vector-based sharpness. sigh....

Adobe Illustrator will fix your problems since it is a vector editing program. Photoshop will rasterise the image which is not what you are after.

Enfocus Pitstop will let you select the areas you are after inside the PDF.

Or, if you had Illustrator you could use you direct selction tool in Acrobat to select the area you want then edit the image which will open in Illustrator, make your changes then save which will automaticly reflect those changes in you PDF
