Variable Documentation

const int FLOAT_NORM_0_255 = 1 << 0

Normalize a float image into the range 0..255.

const int FLOAT_NORM_PRESERVE = 1 << 2

Try to preserve the full floating-point precision, if possible.

For example, in the case of raster files, this flag would be expected to cause the image to be saved in some format with greater than 8-bit precision.

const int FLOAT_NORM_WITH_SCALE = 1 << 1

Display the pre-normalization float range to the user somehow.

The mode of this display may depend on the exact FrameOstream subclass: it might display the original range on the console, or it draw the original range into the new image, or it might display the range in a GUI text box, etc.
