Thank you Liam. That's clear now.

The idea is that you're working on an image that's bigger (in pixels)
than your screen, so you have to zoom in and out a lot. When the brish
size is relative to the canvas, zooming in makes the brush appear
larger (atakes up more pixels on the screen). If you're working with a
300pixel radius brush and you zoom in from 12% to 100%, the brush is
now half the size of your screen! So you have to shrink the brush back
down.

If the brush size is relative to the screen, then when you zoom in, the
size of the brush on the screen doesn't change, so when you zoom in to
100% you can work on tiny details: a brush that's covering 300 pixels
when you're zoomed out to see the full image might be only 30 pixels
wide when you're zoomed in more closely.

It's mostly used for painting, as far as I can tell. So maybe there
isn't much to say on top of what you can already tell people about it?

[Gimp-docs] What is Lock brush to view useful?

2018-09-22 Thread Julien Hardelin

Hi,

I understand what the "Lock brush to view" option does with brush size 
and canvas rotation but I can't see what it can be used for in image 
editing.


In this reference https://github.com/mypaint/mypaint/issues/289 , the 
explanation


/"it is of extreme //
//utility when painting. It allows a very natural 'iterative refinement' 
process //
//with no need to repeatedly ask the application to change brush size as 
you go //

//between the broad strokes and the detailing."/

is not clear for me.

Could you enlighten me?

Julien
