RE: CF Image question...
I am doing a very similar thing. Folks put their thumbnails in a folder, and every night (free) software called Cobian Backup (http://www.educ.umu.se/~cobian/cobianbackup.htm) automatically uploads the new files via FTP. Using CF scheduler, the files are then read in by recursively going through the uploaded directories and adding the files and information to a database. Next I use image CFC to resize for thumbnails and for a watermarked image. I am using CFX_Watermark next to put in the watermark. (I wanted to use CFIMAGE, but I found it was too slow and wasn't getting through images fast enough--between 20 and 200 images get processed every night) Hope this helps... -Original Message- From: Dave l [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 26, 2007 12:35 AM To: CF-Talk Subject: Re: CF Image question...

Re: CF Image question...
The thing I wish it would do is add a permanent watermark on uploaded images instead of only on temp png while being shown. You can do this: 1. Read in original image 2. Read in watermark image (transparent GIF) 3. Set transparency of watermark image to 20-30% Either: 4. Mathematically locate position of watermark OR 4. Resize watermark image to size of original (in memory) THEN 5. Overlay watermark image on original image FINALLY 6. Rewrite original image to drive. This is something that can take the server some time to do - I would suggest using asynchronous processing or scheduled task to handle this.

Re: CF Image question...
This is something that can take the server some time to do - I would suggest using asynchronous processing or scheduled task to handle this. We ran into some issues at my day job trying to use cfthread for resizing images, realizing that if you're doing a lot of it, you can run out of threads in the cfthread pool and the remaining cfthread tags will error out if they don't get access to a thread fast enough. So one alternative that would allow you to resize the images when the user uploads them (no scheduled task) without slowing them down would be to return content to the browser prior to your image editing, i.e. /body /html cfflush / cfimage ... / I do this occasionally in the onRequestEnd (function / template). The drawback is that you can't use cflocation after the cfflush tag to redirect the user if you're going to do that -- and at least with any recent version of ColdFusion you can't use cflocation before any code you want to execute. So if you wanted to redirect the user this way, you would want to use either a meta tag or javascript in the content before the cfflush tag. (and I would include a continue link also) Another alternative would be to use cfhttp / to spawn a request for a page in your application that performs the image manipulation without waiting for the http result content. I'm told there is a way to use cfhttp (a particular timeout value I think) in which ColdFusion doesn't wait for the response, although I haven't personally used it. This way you could span the http request and then redirect the browser with cflocation if you want. hth, ike -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 503.236.3691 http://onTap.riaforge.org ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295339 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Re: CF Image question...
I had thought about that but I figured the overhead was gunna be too much even though its all done on my ded box.

Re: CF Image question...
I'd like to do something similar. In my case, drive space is limited. So, I'd really like to store the image once, but then control how it is displayed totally on the fly. I'd like 3 options.. 1) Display as thumbnail 2) Display full size for web 3) download original picture for printing I'm not super concerned about speed, I just hate all the manual processing and having to upload images into 3 directories (original, display, thumbnail) as I am doing now. Plus, I am rapidly running out of drive space. Any suggestions would be greatly appreciated. My photo directory (about a thousand pictures now) is falling behind because I have such a manual process now. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295324 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

RE: CF Image question...
CFImage cannot read take a filefield like CFFile can (for upload)... However, CFImage source attribute CAN accept a binary blob type object. Theoretically, you can get this directly out of the FORM data without saving it to the system. If you forgo the CFFile upload portion, you MIGHT be able to grab the binary file value directly out out of the Request data. Now, I don't know how to do this :) I don't know how you parse a multipart form data object (which is what the request is at that point I think). However, I don't think all this overhead is worth it. You might as well just upload it, then use CFImage to resize and OVERWRITE the uploaded file. ..

Re: CF Image question...
In my applications, I tend to upload the original into one directory and keep it there, then resize and drop the resized image into the directory where it will be normally accessed. While this would obviously not work in a case where the volume of unsized uploads would cause disk storage problems, I like it because it means that the original is at hand for me if there is some problem along the way... and, if some client calls and says, do you have that picture we uploaded, but we need the original, we lost it, I can produce it for them.

RE: CF Image question...
That's exactly the system of maintenance/use I had settled on, James. And, yes, it's gd to have the original that a client will ultimately need and not be able to find. ;o) I'm going to setup folder structures that will handle all the versions I will need for a site, such as: - Original - Width_400 - Width_100 Etc... whatever the site will call for. And I can add variations as I need to. And if space should ever become an issue, I can always burn the older orginals to a CD or backup to my FTP/Backup server on my network for archiving. It's going to be really nice to be able to upload a photo and have the versions created and deposited in their folders all at once by CF. It has be a *real pain* to have to teach clients how to resize a photo to 400 pixels and to not upload an original photo that would be displayed as a popup that was 2000 pixels wide! And then they wonder what's wrong with the website! Thanks for the tip.
