Here are some ways to tell a image file format. First you can open an unix shell, use the command: imginfo yourfilename to identify the image file infomation likes the following:
On Feb 2, 10:34pm, Roni Kass wrote:> imginfo BTVN.13
Image file: BTVN.13
File format: TIFF
Dimensions (w,h,z,c): 645, 486, 1, 3
Page Size (w,h,z,c): 645, 4, 1, 3
Data type: unsigned char
Dimension order: interleaved
Color model: RGB
Coordinate space: upper-left
Statistical Min/Max: 0 - 255
Display Min/Max: 0 - 255
Data Compression: Lempel-Ziv & Welch
Else you can identify the imagefile format in the indigo magic window, first click the image with the left mouse, then press the right mouse to pop out an menu, at the bottom there will be 'image file info' open it then you can see the image file information.
