define pattern from existing image

Postby jhmicro » Wed Jun 09, 2010 2:15 pm

Hello- I am new to Inkscape... I am trying to figure out how to define a portion(s) of an image as a new pattern(s). This is very easy to do in Photoshop Elements (i.e. make a box around the region of interest, and simply select "define pattern") I want to make the transition to Inkscape especially since I am getting into Ubuntu... can anyone offer any help? Thank you in advance.....

-jh

Sorry for the 101 level question.

The first thing I need to point out is that Photoshop Elements is a 'raster' graphics tool, whilst Inkscape is a 'vector' graphics tool. It's apples and oranges, really. If you want something like Photoshop Elements I would be using GIMP.

But don't let that stop you getting to know Inkscape. You should be able to find your answer at http://tavmjong.free.fr/INKSCAPE/MANUAL ... s-Patterns

1. Convert your Image to a Path...
>Object >Pattern >Object to Pattern (Alt +I)
>Path >Object to Path (Shift+Ctrl+C)

2. Draw the Square above the area you want to turn into a Pattern. Then Convert the Square to a Path... >Path >Object to Path (Shift+Ctrl+C)

3. You will now have TWO paths to work with.. Select both Paths and use the Path Intersection command >Path >Intersection (Ctrl+*)

4. Convert the remaining path to a Pattern (Alt+I)

notes: Once you have your pattern I would use Imagelys (freeware) for bitmap editing vs. Gimp. Gimp's interface is just too complex for me. While Inkscape + Imagelys is an awesome fun and easy set of tools. Inkscape has a bug in it when you expand the pattern, places a vertical transparent line into your pattern. A work around for this bug is to simply duplicate (Ctrl+D) the pattern and Group it and the transparent line will go away.
