I have a pdf form to fill like 500 times and I thought using a gimp python plugin is the way to do it. I have developed the said plugin and I can successfully fill the form except that the text layers I am adding are too sharp. Before I save the file manually, I usually use the blur tool to make the text look like it was filled with a pen. I have tried to do this in the plugin but I can't get i right. I am using the gimp.convolve() function. I guess my problem is obtaining the stroke points of the text layer. Can somebody please help me. Thanks.

1. get the path, and get the polygon approximation of the strokes (gimp_vectors_stroke_interpolate) and then use that with convolve()
   
2. use the path directly with gimp_drawable_edit_stroke_item() after a gimp_context_set_paint_method('gimp-convolve') (but I don't know how to set the parameters to the convolve operation, there is nothing in gimp-context-* for this).

But perhaps using dark gray instead of black, or reducing the layer opacity a bit would work just as well.

If you want to stroke the convolve tool along the text path outline, two solutions:

1. get the path, and get the polygon approximation of the strokes (gimp_vectors_stroke_interpolate) and then use that with convolve()
   
2. use the path directly with gimp_drawable_edit_stroke_item() after a gimp_context_set_paint_method('gimp-convolve') (but I don't know how to set the parameters to the convolve operation, there is nothing in gimp-context-* for this).

I tried the pdb.plug_in_gauss() but I couldn't see any discernible difference may be I was doing it wrongly. 
For the colours I am using a variation of colours (I am simulating filling the forms by hand so I am using different colours with different opacity levels and different handwriting fonts). I will try the solutions and see later.

NB: The gimp.convolve() function's parameters are: 
drawable  - DRAWABLE,
pressure - FLOAT,
convolve-type - INT32 
num-strokes - INT32  Number of stroke control points (count each coordinate as 2 points) (num-strokes >= 2)
strokes - FLOATARRAY - Array of stroke coordinates: { s1.x, s1.y, s2.x, s2.y, ..., sn.x, sn.y }

it is the number of strokes and strokes parameters that I have a problem with.
