The display includes the following information:
Image group
Width The width of the image in pixels.
Aspect The pixel aspect ratio.
Height The height of the image in pixels.
Gamma The gamma value carried in the bitmap file.
Type The type of image, based on color depth. For example, 64 bits (RGBA)
or 32 Bits per Channel Floating-Point (RGBA).
Pixel group
Pixel information includes the pixel location in the bitmap, in parentheses
following the Pixel group heading. The counting starts at 0. For example, in
the above illustration, the pixel in question is the 308th from the left edge
and the 141st from the top edge. Also shown in this group are channel values
for red, green, blue, alpha, and monochrome, both as 16-bit integers (0 to
65535) and as floating-point values between 0.0 and 1.0.
NOTE With high-dynamic-range images, the floating-point values can be greater
than 1.0 or less than 0.0.
Red The red component value (0 to 65535) and the floating-point value.
Green The green component value (0 to 65535) and the floating-point value.
