Re: cfimage: jpg that is really a gif
Guys it's a .jpg but when I get info in ff it says it's a gif. When I renamed it to gif cfomage worked just fine. I am only using it to out put width and height and to warn users if over x y it will blow out a div. Then using cffile for existance and file size. It's just old unscoped input of bad data. When I get time it will be addressed. On Tuesday, November 17, 2009, Leigh wrote: > >> Could it be that they are coded as CYMK images? > > Good thought.

Re: cfimage: jpg that is really a gif
Could it be that they are coded as CYMK images? It's a jpeg format that browsers and Adobe's ColdFusion Image engine cannot handle. Save them back out as RGB (the web version vs the print version) and you may be all right. ~| Want to reach the ColdFusion community with something they want?

Re: cfimage: jpg that is really a gif
I do not know. On the one hand it would be nice if it could "guess" a bit better. But on the other, these images are obviously malformed/misnamed. So I guess you have to work around it. Another option might be to do a try/catch. Inside the catch, try and read in the image as binary instead: ... if it is an image, do something here ... ~| Want to reach the ColdFusion community with something they want?

Not the best option, but you could try and read the image header in the first few bytes. If it is really a gif, it should start with GIF87a, GIF89a, etcetera http://www.w3.org/Graphics/GIF/spec-gif89a.txt ~| Want to reach the ColdFusion community with something they want?
