Transparency under Gimp2.10.6 - carmen - 09-13-2018
Hello!
Having just upgraded from 2.8.14 to 2.10.6, I have met a surprise (for me) in working with painting tools on layers with wholly transparent pixels:
* under 2.8, choosing mode 'darken only', 'soft light', etc., the brush worked only over the already 'painted' pixels, skipping those with full tansparency--never painted or previously deleted.
* under 2.10.6, the effect on painted pixels is as expected, BUT tansparent pixels get filled as per mode 'normal'.
QUESTION 1: is this effect configurable? i.e., I cannot pretend to understand most of the new features--maybe I am missing something?
QUESTION 2: if it IS a new, unavoidable feature, HOW DO OTHERS FEEL ABOUT IT? I find it
* counter-intuitive: how do you lighten/darken WHAT ISN'T THERE?
* no end of a bore to lock transparency to change the color of a small spot (without bleeding out of the drawing), and then unlock to edit the boundary with transparency. In fact, it is almost as bad as editing a masked layer--endlessly checking/unchecking 'edit mask'.
On the other hand, some features (so far) are fine: loading time, memory load, BLENDING TOOL...
Any suggestions would appreciated. Thanks!

On 2.10.6 I did the following:
- open an image (average values of colours)
- add on top a transparent layer
- set mode to darken only
- painted on the transparent layer with a standard black brush : effect=darkened
- changed mode to lighten only : effect=none
Repeated on 2.8.22: got the same results.
Hence, in may case nothing new.

Edit: well that was a waste of time, Note to all users, please give accurate descriptions.

See my reply to I am editing a layer in 'mode normal' with a brush in mode 'darken only'.
Thanks!

Change the brush mode to legacy

Switch on the Alpha Lock?

Works for me:

To clear possible misunderstandings:
- On the top layer, you can paint everywhere, the image below doesn't act as a selection mask
- The top layer applies to the composition of all layers below it, not just to the layer below.
- If you want to apply the effect just on the layer below, you use a layer group.

With a layer group:

Otherwise, make a screenshot of your layer stack (and indicate the layer modes by renaming the layers)

Sorry guys, my fault over enthusiastic editing of everything quoted over a one line reply.
I was peed off after making a comprehensive post on how you might get the reported problem when using layers and how the layer attributes in Gimp 2.10 will be the problem only to find
Not the layers, it is a single layer (I think) in normal mode and brush in darken mode which is different between Gimp 2.8 and Gimp 2.10
Solution as my previous post, put the brush in legacy mode.

This worked like a charm.
Thank you very much!
QUERY: Are other differences worth noting between normal mode and legacy mode?
I am now editing some old .xcf files, and they open with all the layers in legacy mode, whether it be normal, overlay, saturation... So far, I see no change by switching to the new mode--but my eyesight may easily be at fault. Am I missing something?
Thanks.
