Properties of images in pdf file

[sa7ar-yehia]

I have a pdf file of musical notes scanned using Fujitsu ScanSnap SV600. How can I find the properties of the images in that pdf? 

I need to know:

- the format of images whether it is .tiff or .jpeg

- the dimensions of images

- bit depth

- dpi.

Is there a way to find these information in Adobe Acrobat or is this related to Adobe Photoshop?

(Partial reply) Images in a PDF are converted to PDF image format. There is no "TIFF in PDF", there are only images. You can't use Photoshop to get any of this info as it will first rasterise to a ppi you must choose.

Thanks for your reply. So if I have two options in exporting from the scanner [pdf and tiff], it would be better to choose tiff to get higher quality?

In a PDF file the images can be not compressed or compressed using several compression formats: LZW, ZIP, JPEG, JPEG2000, CCITT and JBIG2.

Use the Output Preview as shown below to know all about an image (the foreground image is at the bottom of the list):

PS: when the Output Preview is opened, ALT + click on the image automatically creates a new Comment containing all this information.

PS2 : using the PDF/raster (PDF/R) ISO standard might be an option to consider.
