Star Center Lines of the Selection as Strokes
[attachment=3891]Hello,

I would like to put on specific places of my picture some local grids (composed of 4 squares each).
After some research, I almost managed, but the last part goes astray: here is how i do:
1) Rectangle Select of one of the parts I want to "grid".
(I check "fixed aspect ratio" to get a nice square)
2) I then choose "center lines" down in the select options.
-At that point I have what I need (4 squares), now, I just have to "draw the selection" down on my layer by:
3) going to Edit/stroke Selection

-> but the problem is that only the big square (outline) of my selection takes gets drawn, the inside Center Lines dont get drawn on the picture.

Any idea how I could do that? Like to put here and there square grids of different sizes...?

thanks Smile

Guy

Lots of ways, I think I know what you are after (or maybe not)

Packing in for the day, so rather than reams of text, a little video, just under 3 mins.

@rich2005, thanks for the tip, it was interesting but gave strange result, I think as ofnuts says, that the offset is taken from the corner of the picture.

@ofnuts, it looks like a good plugin, I downloaded the .py file, then copied it in the plugin folder under c:/My user name/gimp/plugin, then restarted the gimp but I cant find it under render/pattern..
Any other place I need to copy it? or do i need to activate it somehow?

thanks Smile

Not so much the corner of the picture, but the corner of the layer, then if the layer = the selection...

Many ways to do this, If as your image, to prevent disaster I would be working on a new transparent layer. Set some guide lines up, enable snap to guides, paint along them, constraining the brush with the shift key.

edit: like this http://docs.gimp.org/2.8/en/gimp-tutoria...lines.html

@rich2005,
yeah..good point, I managed now! Smile thanks, I did like that:
1) new transparent layer,
2) rectangle Select where I need to have it,
3) Layer/Crop to Selection, (so I crop the layer)
4) Filter/Render/Pattern/Grid
It worked good like this for me.

Problem solved, thank you guys! Smile
