Custom Font Effects Pack Bumpmap Option Mini Tut (Gimp 2.10)

Just in case anyone would like a little help with this option I have written this quick tutorial.

The bumpmap option in the CF Effects pack is a quick way of adding a little texture to characters in a custom font. You could apply a texture to an image before using it to create the characters from or you could use the Effects filter to add texture on the fly. You certainly wouldn’t want to add texture to individual character layers – would you?

Obviously you will need a suitable image to use as a basis for your texture – there are lots freely available to use online and you may already have a folder full of suitable images.

Whenever I play about with options I use a small number of characters – or even, as here, just one character – to test things out.

The plain red test character:

I think my example image (uncut turf) came originally from pixabay.com. I have desaturated the image in Gimp (Colors>>Desaturate>>Desaturate) and scaled it proportionally (Image>>Scale Image) to match the height of the custom font. The height here needed to be set to 719 pixels.

Not every textured image requires scaling; bump-mapping will use whatever is available to it.

The one I chose is quite a busy image (many images will work without any adjustment – try them out first) so I used the Threshold option (Color>>Threshold) to create stronger textured lines (settings shown below).

The result of applying the Threshold adjustment settings:

Add the image to the custom font layers with Edit>>Copy (in the bumpmap image view) and then
Edit>>Paste as>>New Layer in Place (custom font layers).

In order for the Effects filter to use a textured bumpmap, the bumpmap layer must be the first non-character layer (ie the first layer not ending with .png) in the layer stack. It does not have to be the top-most layer or indeed a visible layer in order to work.

Call up the custom fonts Effects dialog:
(Filters>>Custom Fonts Tools>>Custom Font Effects Only v 0.0x)
The version number you have will probably be version 0.04 – that will work fine.
Change ‘Add Bumpmapped Texture’ to ‘Yes’ and set the ‘Bumpmap depth percentage’ to 15 or whatever number suits you. By all means play about with the other options.
When you are ready, click on ‘OK’ and let the filter do its thing – the process is quite fast.

Thank you Tom, RJKD and Pat.
RJKD noticed that you had taken on the challenge of Gimp 2.10. It may not be quite there yet - but it is the future. Best of luck - we could do with some Sheffield Steel in the Custom Font construction yard.
