The information window contains a lot of useful information about both the pixmap and the bitmap:
~C~~P22276~
~L~
~SB~PixMap:~SB~
The first section of the information window shows you the pixmap╒s attributes. The inches are measured according to the scale of the currently selected printer. ~SB~W~SB~ is the width of the pixmap in pixels and inches. ~SB~H~SB~ is the height of the pixmap in pixels and inches. ~SB~S~SB~ is the number of bytes this image is taking up in memory. ~SB~D~SB~ is the pixel depth in bits per pixel. The first number is the number of bits per pixel needed to represent the image and the second number is the number of bits per pixel actually used in memory. (Macintosh pixmaps can only have depths of 1, 2, 4, or 8).
On the Macintosh II it is very important the color look up tables (cluts) to begin with white and end with black. Because GIF¬ files can come from other computers that do not have this standard you may see a box around the pixmap information section as shown above. This means that the color look up table in memory does not conform to Macintosh standards. Selecting the ~SB~Squeeze~SB~ PROC under the ~SB~PixMap~SB~ menu ~SU~may~SU~ fix this problem. It is ~SU~very~SU~ important to have the color look up table in the Macintosh standard format if you wish to export files to other Macintosh file formats. Sometimes the image may not even display correctly with Vision Lab until you try squeezing the pixmap.
~SB~BitMap:~SB~
The next section gives the size of the bitmap in bytes. If the bitmap exists it ~SU~always~SU~ has the same width and height of the pixmap. (Of course the depth of the bitmap is always 1).
~SB~Selection:~SB~
If you select a part of the image this section will describe the selection using the same descriptors as in the ~SB~PixMap~SB~ section.
~SB~Paper:~SB~
This section simply describes the printable paper area in pixels and inches for the currently selected printer.
