Re: How to add a frame + caption to another image?

I recently needed to add attributions to a directoryful of
images:

    im=Image.open(fn).convert("RGBA")
    font=ImageFont.truetype("arial.ttf", 15)
    sz=font.getsize(att)
    labelImage=Image.new("RGBA", sz, (0,0,0,0))
    labelDraw=ImageDraw.Draw(labelImage)
    labelDraw.text((0,0),att,fill=(250,250,0), font=font)
    del labelDraw
    labelImage=labelImage.rotate(270)

    # n.b. use the label image's alpha channel as the mask
for the paste
    im.paste(labelImage,(0,0),labelImage)
    im.save(os.path.join(ATT_DIR,fn))

This code draws text in yellow vertically down the image
from the upper 
left. In my actual script, I position the text a little more
pleasingly.

The only interesting thing that's going on there is that if
you omit the 
"mask" argument to the "paste" method
call:

    im.paste(labelImage,(0,0))

you end up overwriting the image with transparent pixels,
which is probably 
not what you're interested in.



The subject suggests you're also interested in adding a
frame around an 
image - I'd probably do this something like so:

    framedImage=Image.new("RGB", framedSize,
frameColor)
    framedImage.paste(srcImage, offset)



Hope this helps,
