That is using an 'overlay' alpha composition on a grey texture of the sort you describe.

IM Examples uses this for highlights, on shaped images, but it can do what you request as well...

Hmmm using builtins.

Code: Select all

convert granite: -normalize -fill '#888' -colorize 80% \
              rose: +swap -compose overlay -composite rose_textured.jpg
The first line is just to adjust the colors of the granite: builtin.
The second overlays that texture onto the rose image on that texture.

If you use "composite" instead of "convert" you can also tile a pre-prepared texture over the image.

I have tested it and it seems to be working properly. Though I'm still working to make the grain texture tile on my image.


Thank you very much anthony :D

No problem. Just remember that the unchanged color should be a perfect mid-tone grey.
EG #7fff7fff7fff.

You can get a good start on a corse fabric texture using...

You can adjust it using the same techiques I used for the granite image

other interesting texture I have in my old icon library include...

I have added a tiled version to the IM Examples, Digital Photos 'Cookbook'.
