Can I view images stored in the Fast Format with Adobe Photoshop?
Yes, you can view images stored in the Fast Format
with Adobe Photoshop. What you cannot do with Photoshop is use the geometric information
included with the product.
For panchromatic data you simply have to load the image file, that's all.
In the case of multispectral data, you must load the data band by band. That way you
can see each separate band. If you have loaded three or more channels, you can merge
these channels to create an RGB image (look for Merging channels in the online help).
If you have less then three bands, you have to duplicate one of the bands (look for
Duplicating channels in the online help) before you can create an RGB image by merging
To load one image file (one channel of the product) do the following:
Select Open As from the File menu.
Photoshop: File Menu
Select Raw (*.RAW) as the format from the Open As
list box. Now select an image file to load.
Check that you really have selected an image file by looking at the
bottom line of the dialog where the size of the selected file is displayed. The size
of header files is around 5 Kbytes and the size of image files is in the range of Mbytes.
Photoshop: File Open As
A dialog where you can specify how the image should be loaded is displayed.
Photoshop fills in values which describe the image correctly in more than 95% of cases, so
that you can simply press the OK button to see what happens.
If you are confronted with more dialog boxes, or you only see garbage
instead of an image, you have to start with step 1 again. You have to fill in the correct
values for the Width and Height of the image in the
dialog. These values can be found in the header file included with the Fast Format
PIXELS PER LINE = 2987
LINES PER BAND = 2880
The other values are always as displayed.
