My Gold Text 2 graph updated but it isn't as good as the old custom bevel. A bug fix on Custom Bevel made Gold Text worse. I'm working on making it better.

To make this graph you need this plugins.

Paste this syntax into Gimp's GEGL Graph Plugin. Make sure your canvas is very large.

Code: Select all

I'm thinking about reviving an old version of my custom bevel plugin as a hidden operation just to make this work flow easier.

I had to make a hidden operation out of an old version of Custom Bevel just to get back specific gold text styles. A bug fix on more recent versions of Custom Bevel broke the authentic gold theme.

lb:oldcustombevel is a special version of the May 2023 Custom Bevel release that can co-exist with the latest version of Custom Bevel. Its hidden so users can not see it outside of GEGL Graph syntax.

Windows and Linux Binaries for hidden gold operation (THIS IS NOT A PLUGIN, IT IS GRAPH ONLY)

Hi I'm finding some combinations of gegl operations very slow when using Filters -> Generic -> GEGL graph.

Can someone please try each of the following three graphs:

1.

ripple ripple

2.

noise-hsv noise-hsv

3.

noise-hsv ripple

I'm finding the first two work quickly, so there's nothing slow about ripple or noise-hsv. However the third is very slow. Is that what you get too?

I think it's because of contention between the two operations over the pixels in the buffer's tiles as they're both being run at once. I see a high number of context switches with a program like dstat(1) suggesting each operation is in its own thread. And monitoring the system calls of the command-line gegl program shows a huge number of futex(2)s compared to the first two.

I have a new plan to get more people into making GEGL plugins.

Document the progress of every new GEGL plugin during its development, starting from the earliest point to the end. Every new GEGL filter I make will get a thread of its own to show its development cycle first, then when it is complete I will edit the first post with a large font announcing the date and that the plugin is done, and link the download on Github. As well as renaming the title from (GEGL namehere Plugin in Development) to (GEGL namehere plugin).

Users will be able to see real time steps I am making in GEGL plugin development and learn how I problem solve and brainstorm about GEGL. If this doesn't inspire people to make GEGL plugins, nothing will.

Two years ago I was making advance GEGL Graphs that styled text. I was not making plugins but I had the understanding of "layer effects" down.

Two years later no one else is making plugins but me.

I have learned three or four unique things about GEGL that Gimp's team never did with GEGL, and arguably likely never intend it to as these are unintended consequences of the c programming and resetting GEGL graphs.

here are those four things.

1. Gimp's team never made a GEGL filter with a blend mode switcher baked in internally.

2. Gimp's team never wrote GEGL filters that call embedded GEGL Graphs with gegl:gegl string=.

3. Gimp's team never used ENUM list to combine multiple filters into one mega GEGL filter, or update their plugins with the new and old version both co-existing as separate graphs that can be selected from a drop down list, or made hidden.

(these three require resetting a .c file's GEGL graph, last is straight forward. )

4. Gimp's team never made a GEGL filter with Gimp only blend modes/options.

These four things are all my discoveries with GEGL. It is possible Gimp's team knows how to do this stuff but they never made a single filter that does these things.

This is also a plugin, for this graph to work download the required 15 binaries downloadable here.
viewtopic.php?f=4&t=20581#p284424

Then paste one of these syntaxes in GEGL graph at a time.
