  Swapping faces
Posted by: Espermaschine - 12-03-2016, 11:22 PM - Forum: General questions - Replies (2)

So for your classic photochop fun: 
swapping faces from one person to the other, 
whats the best way to adjust the skin color so that it matches ?

I usually just eye it with 'Hue-Saturation' and/or 'Colour Balance' and the result is mostly not very great.

There is also this technique:

which i find pretty hard to do.

Also not too keen on the 'Seamless Blending' G'MIC filter:

Advice please.

Just added to the SourceForge collection.

Nothing earth-shattering, it is for the time being mostly a rewrite and repackaging of:

  • delete-strokes
  • reverse-strokes
  • path-splice-strokes
  • path-summary
  • decompose-strokes

  Is there a way to change the size of the font in the error console?
Posted by: Ofnuts - 12-02-2016, 11:21 PM - Forum: General questions - Replies (4)

As title says. Is there a specific theme setting for this or will it change the font in many other places?

  Portable Gimp 2.9.9 for linux
Posted by: rich2005 - 12-01-2016, 03:26 PM - Forum: Gimp 2.10 - Replies (27)

Time to end this old version. There are newer better appimage versions here:

https://github.com/aferrero2707/gimp-appimage/releases/

--------
Edit: - version is now 2.9.9 - everything else applies

Want to keep your existing Gimp 2.8.x and run a Linux Portable Gimp 2.9.9?

Note: This is meant to be used with Gimp 2.8.x - There are dependencies from regular Gimp used by 2.9.9

This works for me in Kubuntu 16.04 64bit.
It should work in other 16.x 64bit 'buntus.  It might work in 14.x 'buntu
It might even work in equivalent version of Mint.
A long shot possibility in other Debian based versions.

Nothing clever, it is assembled using a script and the 'buntu 'gimp-edge' ppa. This updates regularly and I will attempt to keep the following to the current build.

edit: updated 25 December 2017 
Due to updates to GEGL this is only for versions of Ubuntu 16.04 / Mint 18 and later + derivatives
More dependency hell with Ubuntu 18.x versions. This Gimp 2.9.9 appimage is stuck with this release which is Dec 2017
Still very usable, no recent feature additions, just bug fixes

https://my.pcloud.com/publink/show?code=XZbPfJ7ZSkQryGQEr8VICbQTzvPShfoD6SDy 92 MB


Unzip and run. It will run from your home partition. Same as a regular gimp, first run it creates a gimp profile, in this case ~/.config/GIMP/2.9  It will copy all your resources from ~/.gimp-2.8 so to save a lot of editing, temporarily rename ~/.gimp-2.8 and a new empty Gimp 2.9 profile is created.

First run looks like this.

   

I am not keen on those dark themes, so this is my preference + a shot of one nice addition to Gimp 2.9 - new layer options.  Plenty other new things to explore.

   

Plugins edit: 13 April 2019 updated gmic_gimp_qt version 2.5.6 pre and nufraw v0.42
https://my.pcloud.com/publink/show?code=...T26JnF97oy 8 MB

Some plugins that work. Unpack the zip, these go in ~/.config/GIMP/2.9/plug-ins. Plenty of deprecated procedure warnings annoyance, so I advise running as

Code:
GIMP299.bin --pdb-compat-mode=on

bimp17x64 <<< this has a dependency libpcre3 - install that package from your linux repository.
fourierx64
djvu-read <<< mainly for those academic documents

gmic_gimp_qt
gmic_gimp179 <<< last of the series, can be installed alongside ver 2.0 installed.

guillotine-into-layersx64
nufraw-gimp
plasma2x64
plugin-heal-selection.pyThis link is now closed
resynthesizer29
resynthesizer_gui29 <<< small change to gui with added options
smooth-path64

Bugs
This is a development version, there will be bugs.
If Gimp 2.9.9 - any version - crashes a lot, first thing to check is
Edit -> Preferences -> System Resources -> Number-of-Threads-to-use Set this to 1

Final word - absolutely no guarantees Wink Any feedback will be welcome. It might only work on my computer, in which case I will scrap the thread.

  Gimp 101
Posted by: Ofnuts - 11-30-2016, 09:54 PM - Forum: Tutorials and tips - Replies (3)

A list of very useful things to learn to use in Gimp

Gimp is a very comprehensive piece of software and getting fully acquainted with it is a long process, especially when one is self-taught.

Here is a list of things you should learn to use. Some are fairly basic, but could have been overlooked. Some are pure knowledge, but this helps understanding how Gimp works and why some things are done in strange ways. The order is a bit arbitrary, it's a mix of usefulness (most useful first) and skill level needed. Some of it is more useful for those doctoring photos.

  • Basic brush use (photo: Clone/Heal tools)
  • Image transformations: Scale/Rotate, Color mode
  • Knowledge: image file formats: XCF, JPG, PNG, GIF, TIFF: differences, uses
  • Photo: the Crop tool
  • Knowledge: pixel components: RGB and the "alpha channel" for transparency
  • Layers, and basic transparency concepts
  • Knowledge: anti-aliasing
  • "Exploration" tools: Measure tool, "Pointer" dialog, photo: Histogram dialog
  • Basic selection tools: rectangle, ellipse, freehand, magic wand, color. Saving selections in channels. Combining selections (add, substract, intersect)
  • Basic paint tools: Bucket-fill, Blend
  • Basic filters: Blur/Gaussian blur (photo: "Enhance/Uunsharp mask")
  • Levels, Curves, and Threshold tools
  • Basic geometry transform tools: scale/rotate/shear/perspective
  • Keeping the UI manageable: dockable dialogs
  • Extending the Gimp: adding fonts, brushes, gradients, plugins...
  • Using guides, and the Align tool.
  • Knowledge: Colors: the HSV model
  • "Quick mask" selection editing
  • More filters:
    • Map: Bump, Displace
    • Render: Clouds, Pattern, Lava
    • Distorts
    • Noise
    • Blur
  • Advanced transparency control and layer mask
  • Modes for layers and paint tools: normal, multiply, divide...
  • Paths (and path editing)
  • Applying geometry transforms to selection and paths
  • Creating your own brushes, gradients, palettes.
  • Writing your own scripts (for those with some programming background)
If you think I'm missing something (I'm also self-taught) please post and I'll update the list

Something like flickr or deviant user group's collection of signature/art in one thread rather in different post. And thread doesn't need comment, like a photo gallery of sort.

  Add keyboard hint to .scm plugins
Posted by: lumqarz - 11-29-2016, 04:26 PM - Forum: Linux and other Unixen - No Replies

go to scripts folder
find fu-register
example// alexios-duotone.scm

Code:
(script-fu-register
    "script-fu-duotone"
    _"<Image>/FX-Foundry/Photo/Effects/Simple Duotone..."

make change like this w/ underscore (_) before letter
Code:
(script-fu-register
    "script-fu-duotone"
    _"<Image>/F_X-f/_Photo/_Effects/Simple Duotone..."

Some text editor might have option to replace string in all open text document like in Geany ide.

On linux with example above,
Code:
find . -iname '*.scm' -exec sed -i 's#FX-Foundry/Photo/Effects/#F_X-f/_Photo/_#g' {} \;

this only change photo/effect, I failed to use arrays and loop to get it done quicker.
