RE: imageGetEXIFMetadata() getting hammered
Hello The problem with EXIF metadata getting lost is in our track and should be fixed in the next update from Adobe. So a workaround (download img through CFHTTP) can be avoided after that and should directly be able to read the Image metadata from the URL. Also have filed a bug for the problem mentioned by Paul here in this thread.

Hi Paul can you give me the url for a couple images you are having problems with so I can try on my end?

Re: imageGetEXIFMetadata() getting hammered
Hi Paul I had similar problems and blogged about it here: http://www.garyrgilbert.com/blog/index.cfm/2007/8/8/CFIMAGE-Part-4-Remote-Images The problem seems to be only with large images, smaller ones I didn't give me a problem. If you try to pull a smaller image from flickr they tend to discard all the exif data on all resized images only the original has the data. The problem is most people tend to upload the largest size possible (or perhaps its only me). I tried to read the image from the url write it to disk and then read the image back from disk but you end up losing the exif data when you do that (which I would think would be a bug, as well as the "Exception occured in JPG processing. segment size would extend beyond file stream length" error). I then decide to try something quite different :) I used http://farm1.static.flickr.com/97/232021390_ad47422845_o.jpg " path="c:\"/> Which got the image and wrote it to disk with the original name with the exif data intact. I then could read the image in using and get the exif data without problem and output it. -- Gary Gilbert http://www.garyrgilbert.com/blog ~| Check out the new features and enhancements in the latest product release - download the "What's New PDF" now http://download.macromedia.com/pub/labs/coldfusion/cf8_beta_whatsnew_052907.pdf Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:289703 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
imageGetEXIFMetadata() getting hammered
trying to build a lib of EXIF data produced by various cameras, starting w/images from http://www.drewnoakes.com/code/exif/exifImages/ (thanks to seth duffey for the info) trying to grab the data remotely always produces "Exception occured in JPG processing. segment size would extend beyond file stream length" errors on the imageGetEXIFMetadata() bits. copying the images locally produced different results: - some worked ok - some threw java.lang.NegativeArraySizeException errors - some threw 500 errors! java.lang.OutOfMemoryError: Java heap space at com.drew.metadata.exif.ExifReader.processTag(Unknown Source) locally windows explorer could grab the EXIF data just fine in all cases. anybody else see this sort of thing? any workaround? thanks. ~| ColdFusion is delivering applications solutions at at top companies around the world in government.
