Paths Basics

This is a short introduction to paths (also known as "vectors") as Gimp uses them.

• Two points called the "anchors" (A1 and A2, below) that are the starting and ending point of the curve.
  
• Two control points called the "handles" (H1 and H2, below), that indicate:
  • Using the line between the anchor and the handle: the general direction of the curve near the corresponding anchor. For the mathematically-oriented this line is the tangent of the curve on the anchor.
    
  • Using the distance between the anchor and the handle: how much the curve follows the direction of the handle.
    

   

   

   

• The whole curve is always inside the convex polygon defined by the two anchors and the two handles.
  
• They are "compatible" with the simpler geometric transforms (a.k.a. "affine transforms") which are those that are found in Gimp's toolbox: shear, rotation, scale, flip(*). Which means that these two sequence of actions are equivalent:
  • "stroke" the curve to create a bitmap layer
    
  • use a transform tool on the layer
    
• and
  • use a transform tool on the curve (in "Path" mode)
    
  • "stroke" the curve to create a bitmap layer
    
• but of course the curve obtained with the second method will be sharper.
  

   

   

   

• Given a stroke like this (the red part is the Bézier curve generated by the closure):
  

   

• Open the stroke by deleting the segment between the two target anchors (2 and 3). These two anchors becomes the start and end of the open stroke. The handles are preserved:
  

   

• Now, reconnect these anchors. The Bézier curve is regenerated, so the stroke shape is the same as initially, but the start and end anchors are the ones delimiting the temporarily deleted segment.
  

   

• This technique can be generalized to have the stroke start on any point. Just add an anchor on the path by Control-licking the path where you want the stroke to start. Then use the technique above, removing and adding a segment that ends on that new anchor.
  

• Using the "Text-along-path" function
  
• Rendering the stroke by painting it with a gradient
  

• One singe stroke for the 'h'.
  
• Two strokes for the "o", the outer outline and the inner hole.
  
• Two strokes for each "b", the outer outline and the inside for the loops.
  
• Two strokes for the 'i', one for the body and one for the dot (a.k.a. "tittle").
  
• One singe stroke for the 't'.
  

• Gimp processes the path as a whole, there is no way to restrict its action to specific strokes.
  
• The path is associated to the canvas, not to a specific layer.
  
• A path can have points that lie outside of the canvas
  
• Coordinates of anchors and handles are not restricted to integer pixels. Sub-pixel paths are possible
  
• Selection from paths where strokes are not disjoint follows an 'even-odd' rule. Starting un-selected from a border, the selection state changes each time it crosses a line. This is neither and intersection nor a union, but a rule that creates the expected selection on text (unless characters overlap).

Initially posted in r/Gimp on reddit.

This is something I can not wrap my head around no matter how many different articles I read, so I am hoping that by posting here someone will give me steps that make sense. 

I have an image that is 2201 x 1240 x 72 ppi.  I want to take a portion of it and make it 8-1/2" x 11" x 300 ppi to put on the cover of a magazine in Scribus.  I achieved this in Photoshop CS2, but I can't for the life of me, get it to work in GIMP.  The image comes in huge and when scaled to the frame, reduces the ppi to way too low, or the image comes in too small, and still doesn't work when resized. 

Please, please, please walk me through the steps of making a selection, cropping, resizing, setting the print size and the ppi and making sure that when I bring the file into Scribus, the image will be exactly sized to an 8-1/2" x 11" frame and be 300 ppi.

I don't know why this is so hard for me.  I have more than one Scribus book, for artist and photographer, and I have read online tutorials and the help file about resizing, re-sampling and setting print size, yet I can't get it to work.  I have to go to bed because I am so stinking tired, but I will check back after Thanksgiving dinner tomorrow night to see if anyone has come up with a way to help my oh-so-thick self.

Thank you.

Hello.

Two .xcf files are opened.  File-01 and File-02.  Both have a resolution of 72x72 ppi.  

I copied a layer that is in File-02 onto File-01, then scaled said layer such that it is now significantly smaller and looks like a thumbnail.

The problem is that I cannot make this resized layer as sharp as it was in its original size.

I need to print it as a flier so I need the pictures to be sharp, even if they are small.

Any ideas?

Thank you for your time.

Using Windows and having problems finding and installing up-to-date resynthesizer / heal-selection plugins?

I bundled the required files into a zip 

http://www.mediafire.com/file/gwc928wmwt..._32_64.zip

There are some horrible advertisements on mediafire these days. For a 64 bit resynthesizer + the heal selection python plugin there is a download here:
https://www.gimp-forum.net/Thread-Resynt...7#pid12687

Download, un-zip, use either the 64 or 32 bit versions of resynthesizer & resynthesizer-gui depending on your Windows installation.

Gimp 2.8
Copy the required files into C:\Users\"yourname"\.gimp-2.8\plug-ins

Gimp 2.10
Copy the required files into C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\plug-ins

For Gimp 2.8 - Gimp 2.10 is similar. This video about installation in Windows 10. 3 minutes duration.

I tried working on this image i posted earlier, because there is something i dont like about it, but i cant quite put my finger on it.

Is it because the perspective of the sunray does not go with the perspective of the text ?
I think my main complaint is the white outline, that i added for contrast, but it looks odd to me....

Tried using a trick learned from Phlearn (YT channel) and look at the image in b/w.
It looks good to me, with the exception that the white outline perhaps steals the show from the extruded text...

Maybe its really because the perspective of the text is odd. We are looking at the text from the top, but at the same time its extrusion is going up.

I find it really hard sometimes, making something look professional....
