Start a new path when creating lines in GIMP.
How to create lines in GIMP?
Select the pencil tool from the toolbox, make sure the foreground color is not the same with the background color or else the line will be invisible.
If you need to specify a brush select the "brush" that you want to use to create the line.
Press and hold the "shift key" then select or click the start point.
Click the second point (while still holding the shift key) and a line will be drawn.
Release the "shift key".
If you want to draw again a new line, press "shift key" but you will notice that the line will be connected to the last point that the line was drawn.
This will happen if you didn't "double click" on the last point that the line was drawn.
Even if you press "esc" key it will still continue from the old point or the new line is still connected to the end of the line that was previously drawn. Or if you’re doing a selection the new area that you’re selecting is still part of the old selection.
To start a new line or a selection, make sure you double click to end the selection or end the line.
If you forget to double click in order to end the selection or end the point for the line that was drawn, press "q" and it will end the selection or if you're drawing a line it will start a new point.
That’s the simple trick is to “double click” to terminate the path or the point. So you next line or selection will begin in a new path or area.
But if you forget to double click, press “q” key to quit or end the current activity.
Cheers! Have fun. Please share any tricks you have or drop a comment below. Thanks.
