Newbie Ask: 1) Select Object? 2) Rectangle line thickness 3)delete path node - Fran3 - 02-24-2018

I'm running 2.8.22 on Windows 10.

I've watched a few videos and done some Googling but still have some questions...

0 - First I should ask... is Gimp vector based or a bitmap program or what?

1 - Once I create/design a shape with the Path Tool and go on to use the Rectangle Tool to create and Stroke a rectangle...

How can I "re-select" the shape created with the path tool so I can perform additional edits?

2 - When I use the Rectangle Tool to create a rectangle and Stroke it as a Solid Line... say 5 px...

Why are the vertical lines of the rectangle wider than the horizontal lines?

(Image area = 1,000 by 1,000)

4 - When I create a closed path with the Path Tool and switch to edit in order to curve the nodes... I saw in one tutorial you could click the node to delete it... but I can't seem to make that work...

4a - How to delete node on closed path?
4b - Why when I go back to design mode on the path it seems to work like edit mode in that I can click a node and curve it?
4c - I can only seem to move a node by going back to design mode... right?

Thanks for any help.

Wow...

Gimp is very definitely a raster(bitmap) editor. While there is a path tool Path

any output from Gimp is a bitmap

Quote:1 - Once I create/design a shape with the Path Tool and go on to use the Rectangle Tool to create and Stroke a rectangle...

There is no rectangle tool. There is a Rectangular Select Tool SelectRect

. The selection can be stroked to create a rectangle.
There are additional plugins that can create a shape-path (includes rectangles) that, same as the selection can be stoked to create a rectangle.
This is a nice easy to use one for a newbie to start with: http://registry.gimp.org/node/59 not the most sophisticated around but makes clean paths. There is also a very old standard gimp plugin gfig, Filters -> Render -> Gfig which might do you until you find something else.

Generally you can activate the path tool, make sure the path is active, click on the path to show the nodes and handles.

They are no different unless you have messed about with horizontal and vertical image resolutions. Even then they are still the same number of pixels, only view/render different.

Try holding ctlr-shift down, cursor needs to be over the node, cursor icon changes.

Same as above

Quote:4b - Why when I go back to design mode on the path it seems to work like edit mode in that I can click a node and curve it?

Hold the ctrl key down to go into edit mode, click on the node to bring up the handles
or
Click-drag on the path between the nodes to bring up the handles, then adjust the handles.

Quote:4c - I can only seem to move a node by going back to design mode... right?

Yes design and edit modes have different actions.

------------

If you want to enhance path functions then a good additional plugin is Ofnuts ofn-path-edits from
http://sourceforge.net/projects/gimp-path-tools/files/scripts/ about 4 down in the list.

Very helpful. Thanks.

Followup:

I asked... "How can I "re-select" the shape created with the path tool so I can perform additional edits?"

You answered "Generally you can activate the path tool, make sure the path is active, click on the path to show the nodes and handles. "

I use the path tool to create a closed path and stroke it... then use the rectangle selection tool to draw and stroke a rectangle elsewhere on the screen

Next I Open the Path Dialog Box and double click on my original closed path and see the nodes lite up on the path...

BUT... when I move one of the nodes it appears to actually be a copy of the original closed path as when the node is moved I can still see the original path below it ??

So, I apparently am not doing something right... my goal was to re-select the original path and relocate some of its nodes and modify the shape.

What am I missing?

Thanks again for the help.

Are you seeing the stroke (bitmapped pixels) from the original path.

Gimp is a raster editor. There are no "objects" as in say Inkscape (or have you been using PS)

Always work on layers. Delete the original layer. Make a new layer. Stroke the revised path.

RE: Newbie Ask: 1) Select Object? 2) Rectangle line thickness 3)delete path node - Fran3 - 02-24-2018

Ah ha. New Layer... got it.

FYI, I've been using Inkscape and Corel Draw and Corel Paint.

I was hoping to drop Corel and go to Inkscape for Vector and Gimp.raster/bitmap.. or do you have another suggestion?

And yes, I have to remind myself that there are no objects in Gimp... just like on a more simple scale PC Paint.

Thanks again for your help.
