Hey Aaron.
I’m watermarking framing a bunch of client logos on to a transparent PNG to get them centered and all that. However some of the logos are getting a black background and artifacting the original logo instead of transparent.
Here’s an original logo file: http://cl.ly/Ns4u
And a watermarked output sample: http://cl.ly/NsIo
Here’s my CE Image pair/single to watermark.:
{exp:ce_img:pair src="{client_logo}"
height="50"
width="100"
alt="{title}"
parse="inward"}
{exp:ce_img:single
src="/assets/img/watermark_100x50.png"
height="50"
width="100"
crop="yes"
disable_xss_check="yes"
watermark="{made}|0,0|100|center,center|0,0"}
{/exp:ce_img:pair}
Any thoughts? Thanks dude!

Hi AJP!
Would you mind emailing me the source images you are using so I can test them out?

Yeah, that’s interesting. I’m not sure what would cause that. Were the images saved as 8-bit pngs, or losslessly compressed? Sometimes preprocessing images can confuse the GD library. Merely opening up the logo images in Photoshop and re-saving them fixed 3 of the 4 logos.
Since all of the images have a solid white background, you can add
save_type="jpg"
to the ce_img:single tag to save them to jpg format. That completely resolved the issue in my tests.

Saving as jpg worked. Hopefully we’ll get some new logos from the client that would resolve this as well.
Thanks!
