Re: Thumbnail tags
I've been using cf_gifgd from the tag gallery works good for me, but progressive jpg's will break it. If anyone has any better solutions I'd like to know also.

RE: Thumbnail tags
I'm also looking to get/purchase a thumbnail tag, but one that does a decent downsampling by interpolation -- merely throwing 4 of every 5 pixels away, for instance, causes artifacts. Additionally, I am looking to purchase a compositing tag for image watermarking. It needs to be able to handle an alpha channel composite where one image is larger than another. I could write this, but I'd just assume use somebody else's since most of the effort will be spent writing the decompress for jpegs and handling file formats. If you have source that will open jpeg (and gif, png) images and write them to rgb buffers, that would be enough of a start to finish this tag and distribute it...

Re: Thumbnail tags
> I've been using cf_gifgd from the tag gallery > works good for me, but progressive jpg's will > break it. If anyone has any better solutions I'd > like to know also. I too have been stuck with cfx_gifgd and its problems with progressive JPEGs. I've looked, but haven't found anything that is a good replacement. If anyone knows of a good alternative, I too would be very interested. However, I do know how to test for progressive JPEGs before resizing them. The problem is that when CFX_GIFGD is called to resize a progressive JPEG it causes the entire CF service to crash and restart, which is obviously a bad thing. I don't know enough about JPEGs (or the CFX code) to know why this is. To ensure that this won't happen, use CFX_GIFGD to read the file before you resize it. The READ action returns a series of variables about the image, one of which is the file type. If the image is a progressive JPEG the type variable will contain an empty string. Just wrap the resize action in a CFIF that checks the length of the type variable. For example: Just a little workaround I discovered. Hope it helps.

Re: Thumbnail tags
I'd use Jukka Manner's updated CFX_Image tag instead of the old CFX_GifGD tag. It has support for progressive jpegs as far as I can tell, it also has much more features. - Original Message - From: "Seth Petry-Johnson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 11, 2000 8:30 PM Subject: Re: Thumbnail tags > > I've been using cf_gifgd from the tag gallery > > works good for me, but progressive jpg's will > > break it.

Re: Thumbnail tags
you can use the CF_GifGD and when you encounter a progressive JPEG use CGX_Image and CFX_ImageInfo to handle the resize.. I haven't used CF_GifGD but I plan on using it with this combination..

A progressive JPEG will display in the web browser in several passes, with more detail reveal with each pass.

RE: Thumbnail tags
Actually I got CF_AutoResize to work. I came up with numerous bugs but it finally ended up that the commands to cfx_image in the source code for autoresize.cfm were not delimited correctly. As soon as I fixed that it worked like a champ. I also had to add some more error checking so that it will not allow files that are not image files.
