It was the resampling that was complicating the discussion...my bad...
But that brings me back to my original question about the CF image
manipulation tags. I want to be able to automatically resample the images
for display so the file size is smaller while keeping the originals (if they
are
scanned or taken at higher resolutions) at the same ppi.
I don't know yet whether or not any of the tags will perform that function.
I want to be able to upload a hi-res 8x10 image, have it downsized
(dimensions only)
to a 5x7 and 4x6 (still at same ppi, if the camera's ppi setting is
variable)
then resample the image to 72 ppi for display on the website. The 8x10,
5x7, and 4x6
are for downloading, saving, and printing...that's what I'm trying to
accomplish.
Anyone know what tag can do this? CFX_Image? CF_MagickTag/ImageMagick?
CFX_ImageCR from Efflare?
If CFX_ImageCR can accomplish all of that... ppi manipulation and
resampling, too,
then it'll be worth $149, easily...
Thanks for your help...
