So you've given up with ImageMagick? Fair enough. Just out of curiosity, did you try correcting the commands as I suggested above?

Good theory, but the second command expands to: and I assume it should expand to:

Yes, the first frame (or any frame) can be resized, eg: How many frames are there? List the frames:

I think your commands are screwed up. They mention "convert" twice. For example, the first one expands to: convert C:\ImageMagick\convert uploads\17364.pdf uploads\thumbs\Test.png 2>&1 From the error message, we see that "convert" is running correctly and looks for an image a...

I don't use PHP so I could be wrong, but I think exec() doesn't need libraries; it just executes a command, as if it had been issued from the keyboard.

It would be good if all (x,y) coordinates could be given as percentages of (width,height). Sadly, they can't, and we have to do the necessary caculation in a script.

The image contains no circles at all. It does contain a number of marks that are reasonably close to being circles. You need to decide what determines "nearly a circle". A possible approach would be to choose a possible centre and radius, draw a circle, and count how many corresponding pix...

According to Wikipedia , LogLuv stores one channel in 16 bits and the other two channels in 8 bits each. A developer would need to comment on the feasibility of implementing LogLuv: adding the colorspace conversion functions and modification to file read/write functions. It could be simulated, with ...

It's not just a shadow but also a reflection. In the sample image, it merges with the object. Automatic separation would be very difficult and probably unreliable.

I'm not sure what you are asking. exiftool reports:

It works for me (v6.8.6-0 on Windows 7) in the sense that I can convert it PDF then from the PDF to PNG and it looks the same (in Microsoft Photo Viewer). However, Adode Reader X (v10.1.7) shows a blank white page, 32 inches wide by 200 inches high. I suspect this software can't cope with such a lar...

Export as text, and search for the corners ("most north-westerly point", etc) in a script. Yes, that looks like a sensible method. Thanks.

gowribala: Can you post a sample image? Put it somewhere like dropbox and post the URL here.

I'll add another thought here. Perhaps the OP wants the logo to appear on the photo, not only in the correct location, but also with the correct perspective. This would involve (a) finding the corners of the blue patch on each image, then (b) applying "-distort perspective" to the logo. St...

I used to have problems doing this with Gimp, probably building the layered tiff from different tiff files (with different types).

Yes, good points about the standards and "-type least_common_denominator".
