Hello all...

I�m a Master Degree student at University of S�o Paulo (Electric Enginering Dept)- Brazil.

My research project consists in developping an image processing software related with medical images, mainly focusing on mammograms digitized images. The objective of the project is to work with 12 bits/pixel grayscale images.

We use UMAX PowerLook II scanner and Adobe Photoshop 5.0 to digitize the mammograms and we are now using TIFF format to save our 12-bit-format images. However, to process this images we must convert this images into a data matrix, where each pixel on this image will represent an element of the matrix and the value on the matrix will express the grayscale level of the corresponding pixel.

To implement this transformation (12-bit image into data matrix) I must know HOW Adobe software saves this TIFF format, I mean I need to know the structure used by Adobe on saving the TIFF format when using 12-bit grayscale images. For this reason, I�d like to ask you if you have this kind of information or where I can get it.

Thank you for your help,
Sincerely,

Mauricio Cunha Escarpinati.
