script to merge files into layers and set a layer mask |
Posted by: DanielDD - 09-09-2020, 01:18 PM - Forum: Scripting questions

Hallo,
I need a script for batch mode:
There are files t0.tif and t1.tif (single page tifs) in the current directory.
The script should open these files and put them into a single file as layers
(t0.tif as bottom and t1.tif as top layer).
Then, the script should set "grain merge" to the top layer and add a white
layer mask.
I am somewhat familiar with (scheme)lisp, but I have no knowledge on
script-fu.
Finally, the script should save the file in standard gimp format.
Daniel

preview larger |

Hey my lovelies I am trying to use to the filters that come with gimp. I was wondering is there anyway I could make the preview larger for the plugins (like Iwarp). What I am working on now is way to small for me to see I have resized the window but that didn't help. I wear glasses and it still is to small for me to see. Is there any way I can fix this? Thanks in advance

Need gegl to build gimp, and can't build gegl |

Esteemed Colleagues:
Readers of this forum know that I recently built gimp 2.10
from source, and it was a nightmare, but I did it.
Now -- apparently in search of suffering, for there can be
no other reason for trying to do this -- I am trying to build
gimp 2.10 from source again, for another operating system
that shares the same hardware (my laptop is a multiboot
machine, I have several operating systems installed on it).
Because gimp 2.10 has many dependencies that are newer
than the versions available thru my package manager -- or,
in some cases, not available at all thru my package manager
-- I have had to build those dependencies from source. Only
one unbuilt dependency now remains on this operating system,
gegl.
I cannot build gegl on this operating system. That, of course,
is surely not true, what I mean to say is that I have not figured
out how to build gegl on this operating system. I turn to you,
esteemed colleagues, for help once again. This is the error
message that I get, time and time again, no matter what -f
arguments I have given to the compiler (and I have tried
many):
operations/external/exr-load.so.p/exr-load.cpp.o: In function import_exr(_GeglBuffer*, char const*, int)':
/usr/local/src/gegl-0.4.26/build/../operations/external/exr-load.cpp:506: undefined reference to Imf_2_1::Chromaticities::Chromaticities(Imath_2_2::Vec2<float> const&, Imath_2_2::Vec2<float> const&, Imath_2_2::Vec2<float> const&, Imath_2_2::Vec2<float> const&)'
This is at operation [481/750] of the ninja build.
Most likely this is a missing constructor that should have been
created from a template, but which the c++ compiler is failing
to create. But templates have been around for a long time
(31 years, in fact -- I remember when Bjarne Stroustrup
announced them in the Journal of Object-Oriented Programming;
but I digress) and I am using gcc 9.2.0. Surely by gcc 9.2.0
the g++ compiler has managed to get templates right. So
what is going on? I suppose I could build clang from scratch
and then try to build gegl with clang++, but I am certain that
this is not a compiler problem. And yet, this same version
of gegl has been successfully built before. So why can I not
build it on this operating system? What do I have to do?
As always, I thank you in advance for any and all replies.

Testing a new script. If you look at this picture long enough, you will perceive a full shape in the middle (middle "deeper" than the rest).
(open image in a new tab, and zoom it so that the image is about twice as big as the distance between your pupils)

Docks Keep Disappearing |

I am new to GIMP. Anytime I open a dock like Color Balance, Exposure or Curves, the moment I make edits with it and click "OK", the dock just disappears. I don't know how to recall it, especially when I want to adjust something I have done. I found a place to click under Windows called "Recently Closed Docks" but it just never works. Is anyone else having that problem please? I use a Macbook.

Can't print whole image |

Hi
I've just switched to a new laptop, and I'm finding that I can't print the whole image. Approximately 14% of the width and height show as blank on the image preview - blank strips to the right and bottom. I can't find any reason for this! Anyone know what is causing it?

Disable antialias/filter when deleting a section? |

This must be something extremely basic, but I can't figure it out.
I have a selection which I am trying to delete. The layer has an alpha channel, but I want it to stay true to the selection (that is, EVERYTHING in the selection is deleted, and EVERYTHING outside the selection is maintained). When I select it and delete, this happens:
this
goes to this
It looks like some kind of antialiasing or texture filter, how do I disable it? As in, the selection needs to be 100% cleared to alpha, and the pixels outside the selection need to be untouched.
