I would like a script that would take normal text layers and turn them into a text art like this

You would open the script dialog and it gives you a few options
Select image layer (user input)
Select text layer (user input)
Select font ( sans default) - allow choice
Set line spacing (-6.0 default) - allow user input
Set bg color (black default) - allow to choose this color
Set color inverted text layer mode (grain extract default) - allow to choose
Upon hitting ok the script would do this -

1)Take the selected image and add an alpha channel if none exist.
2) Take the selected text layer and alpha to select it. -set line spacing
3) Select the image layer and copy paste new layer on top.(this copies text to new layer on top)
4) duplicate that layer and color invert it
5) set that color inverted layer to grain extract mode.
6) add a black layer on the bottom.
The user would have to make the original text type and image layers invisible unless the script could do this also.

Results

I second the request!

...and what text for the text ?
1) a user input i.e. "i must stop to write nonsense!" to repeat over and over
2) or just random letters ?

personally i will prefer the first

No PC, the user input would be a text layer selection.The user would have already created the text on a layer by itself.Two layers would have already been created - image and text layer.Then you run the script.



Sorry Paynekj.Guess i didn't make that very clear.
I suppose the user could also have already set the line spacing. (width between the text lines)
When the text is copied and pasted into a new layer it actually copies the colored image as text.Basically you are just cookie cutting or cookie copying in this case.
Once you select the text (alpha to selection), you then select the image layer and select edit>copy>edit>paste into a new layer.That layer is then copied.Then it gets inverted Color>Invert
Then that inverted layer is set to grain extract.

Here is a xcf of type for you guys i created in Gimp-2.7.4
You can just use it for testing if you like.



1500x1500 with line spacing set to -9.0

This is the result from that text with the same image.


Here is the whole xcf file

Can't you use...

gimp-layer-set-mode

in Script-Fu?

You can create a SF-OPTION drop-down that mimics the one in the Layers Dialog with the following registration:


You then can use the requested mode as an index into an array that contains the GIMP's enumerated values for those modes (which I've shown as comments above).

Yes, but that's not the problem. It's in the user-interface. There isn't an equivalent to SF-COLOR, SF-FONT etc for the layer mode. BUT a quick bit of googling has lead me to the joys of SF-ENUM, for example:
SF-ENUM "Effect Layer mode" '("LayerModeEffects" "grain-extract-mode")

(For reference the SF-ENUM is in the Gimp Docs: http://docs.gimp.org/en/gimp-using-scri ... cript.html and I found the Gimp Enums defined here: http://developer.gimp.org/api/2.0/libgi ... enums.html and I had to guess the "enum value's nick. ")

Edit: I got Ninja'd by Saulgoode , but I prefer the SF-ENUM route as I then don't have to maintain a list of "magic numbers".


So I've attached my first go at this for you to try.
As I hate scripts burying themselves in the menus it's my standard practice to register my scripts in a "contributed" menu. You can edit it to suit yourself.

That is understandable, though my own preference is for the options to be in plain English* rather than a C name (e.g., "Normal" as opposed to "GIMP_NORMAL_MODE"). Also, there are a couple of paint modes ("Behind" and "Erase") that don't apply to layers.

* If the string constants were prefixed by an underscore (e.g., _"Normal"), then the words would automatically get translated to other languages; this would not be true for the names of GIMP's enumerated types.

Great!!

Trying it now.

Excellent!


I have not tried the other modes yet but this works great.

Thanks again.

My Piranha Wolverine

Unsharp mask (2.85) on the normal text layer.

New from visible -duplicated visible layer
set top layer to screen mode.



These look totally awesome paynekj! I am very, very happy with this.
Excellent job on the script.

I love this script.This is a photo of a bridge in some woods my Wife and i frequent quite often for our walks.

I didn't notice that user selection of the layer mode was part of the specifications, but more versatility is usually better.

Here is one that I made back in 2006 using this technique:
