Lomo Effect for 2.9.9 - dinasset - 03-11-2018
Hi.
I'm playing a bit with 2.9.9 and to train myself I started writing some very small filters.
This one is not ORIGINAL, i.e. has not been invented by me: I took a couple of two small existing filters (in .scm), combined into just one and ported into python.
The original filters are:
- Alexia Death's script-fu-lomo-effect and Avi Bercovich's script-fu-lomo
Comments, critics, suggestions are welcome.
If someone is interested in the originals I attach here also those.
They are the versions I have in my folders, menu has been modified, they will appear under BestFilters/Photo/Effects (I do not remember the original menu).
My filter will appear under menu="<Image>/Diego/Ancillary2"

How is it different from the G'MIC Lomo effect ?

A comparison in my Gimp 2.9.9,

edit: Ran the plugin again with the compat-mode switch off.
No errors, so future proof until the Gimp developers throw in some more weird code.

**cough**
Code:
pdb.gimp_context_push()
currFG = pdb.gimp_context_get_foreground()
currBG = pdb.gimp_context_get_background()
# [... snip ...]
pdb.gimp_context_pop()
pdb.gimp_context_set_foreground(currFG)
pdb.gimp_context_set_background(currBG)Context push/op operations are designed precisely to avoid saving/restoring colors and other context elements (pattern, font, gradient...)
Otherwise, what is specific to 2.9.x in the code?
RE: Lomo Effect for 2.9.9 - dinasset - 03-12-2018
Nothing specific, just the way to set the layer's mode is typical of 2.9
About the FG/BG saving/restoring: some times ago I noticed (on 2.8) that the push/pop operations were not enough for them (OK for pattern, font, gradient), hence I specifically added those.
Didn't try yet if that was a temporary bug on 2.8.

Works for me on 2.8.22. Even better, it seems that of you do one context_push() there is an implicit context_pop() at the end:
Code:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from gimpfu import *
def testContext(image,layer):
gimp.context_push()
gimp.set_foreground(0,0,255)
layer.fill(FOREGROUND_FILL)
# gimp.context_pop() # doesn't even seem necessary
register(
'test-context','Test context','Test context',
'','','','Test context','RGB*',
[(PF_IMAGE,'image','Input image', None),(PF_DRAWABLE,'layer','Input layer', None)],[],
testContext,
menu='<Image>/Test'
)

Very good info !
