| Output positioning options used by Gimp when printing to CUPS |
|

I am trying to figure out what CUPS (or would it be lpd/lpr?) printing options Gimp uses to set the output position when you print an image.
When you set the Left/Top fields in the "Position" print dialog tab, I guess Gimp uses some job printing options through CUPS/lpd/lpr to adjust the output image on the media.
I need this information so that I can try to print images (outside Gimp) in the same position regardless of the printer being used.
Does anyone have this information?
Thanks.

Single Dose - Glossy stroke 3d.py |

Hello everyone!
Plugin: glossy_stroke_3d.py; (I don't remember where I got it)
Author Eric Leroy;
Date: 2010;
Problem:
The plugin only works once for every Gimp restart.
After a single use, the plugin stops responding. Requiring the Gimp to be restarted so that in just one more instance the plugin will run again.
The plugin can be found in <Image>/Filters/Light and Shadow
Would it be possible to detect the cause of this problem and somehow fix it?

| How to move text? |

There are two layers. One is a background image and another one is text. The text is above the image. Every time I move the text with the move tool, the image is moved mostly.
It works sometimes, but not mostly. Why does it happen and how do I figure it out?

Every time I resize a layer, I can't see the bottom layer.
For instance: There are Layer 1 and Layer 2. The Layer 2 is over the Layer 1. I resize the Layer 2 and can't see the Layer 1, so I can't resize the Layer 2 whatever I want.
Is there a way to make the upper layer transparent?

Hey, I am on version 20.10.30. I need to know how to adjust pen pressure for size/opacity at the same time, like Photoshop. How do I adjust the new brush dynamic? I don't see any way to edit brushes (new ones) .. I can change thing in the mapping matrix for a new brush, but it didnt change anything, even when I adjusted the curve.
So basically, how do you adjust pen pressure for size/opacity at the same time.
Thanks.
