How to create hatch pattern inside a polygon


We use Acrobat's drawing tool to make polygons over an existing map.  Up to this point, we have used solid fills inside the polygon.

Last week,  I received a request from my client asking me if we  can use a hatch pattern instead of the solid fills.   There are about 30 polygons that will need this hatch pattern to be done.   I can do this manually using lines, but it is very tedious, and for 30+ it will take forever to do.

Is there a way to do this within the software, or is there 3rd party software available to do this?

Thanks in advance for your replies.

As in any case when you have powerful tools, there are some different ways to go about this. Here's one approach:

"Open" the PDF (you may get a dialog box with information about the resolution you want).

Use the Marquee tool and/or the lasso tool to outline the area you want to fill.

Select the Paint Bucket Tool (hit the g key on your keyboard). In the top toolbar, look at the options for the tool, one should say "Fill", pull it down and change it to pattern. Next to it should be your choices of patterns. There is a wide range of patterns available, if you don't see one you like, you can create your own. Use the Paint Bucket Tool to fill the outlined area with the pattern of your choice (you can also set transparency before you fill).

Save AS and save as a Photoshop PDF


Acrobat's drawing tools are pretty simplistic. I don't believe there's any way within Acrobat to do a textured fill, only a solid colored fill.

Photoshop should allow you to edit your PDFs and overlay drawings with whatever background you want.

Hello LHerrou,

OK.  I do have Photoshop.  What would be the process involved in order to put the cross hatching on the PDF?  I am not a savvy user of Photoshop, at all.   So if you can be specific, that would be great.  

Here's what I've tried so far:

I have tried to open up a PDF in Photoshop, and am already lost.  Do I "import" it, or just "open" it (the PDF)?

Once in, Photoshop, I can see the tool to make a rectangle or polygon, alright, but how do I put the hatch pattern inside it?

And will I be able to save it (the PDF) so it can be brought back into the other PDF with the relevant multiple pages of text that will need to accompany the map?

Thanks for your feedback on this, BTW.

OK. I got you.  I tried, but could not figure out how to match the pattern I need.  I've attached a JPG showing what I want to achieve.

How do I create my own pattern?  See above to see what I'm desiring as far as a pattern goes.
Sorry, somehow I missed your posts (my spam filter does funny things sometimes) asking for more information on making your own patterns... if still needed, here's a good tutorial on the process:
