That would be ideal but my tests are not getting at the sub-image. [EMAIL PROTECTED] convert 'test.tif[1]' thumb.jpg convert: UnableToReadSubimage `test.tif'
If, in PhotoShop, I use the open dialogue box and browser a folder with this image in, it manages to display a small thumbnail in the bottom of the dialogue box. It displays a preview for all the images in this folder and they are all greater than 50MB. These files were last edited by PS. I suspect that these thumbnails are embedded somewhere in the file (perhaps the Photoshop 'Image Resource Blocks' private tag) but not readily available to IM. I can't image that PS is going to create a thumbnail on-the-fly to display a preview in the open dialogue box. If I query the tags in the TIFF with AsTagviewer it shows the PhotoShop block as being a little under 6K. Which is about the difference between a image with a saved preview and one without. Am I making sense? Does that seems possible that there is a sub-image that is stored within a private tag? Does anyone have any ideas or information about this? Thanx. Dp.
