Reads a radiance HDR image from FILE into a vector
of (UNSIGNED-BYTE 32) if FORMAT is :RGB9-E5, or SINGLE-FLOAT if format
is :FLOAT. If Y-UP is true, data is stored with bottom row of image
first, otherwise top row first.
Reads a radiance HDR image from STREAM into a vector
of (UNSIGNED-BYTE 32) if FORMAT is :RGB9-E5, or SINGLE-FLOAT if format
is :FLOAT. If Y-UP is true, data is stored with bottom row of image
first, otherwise top row first.
Write HDR to FILE, with ’new rle’ compression unless UNCOMPRESSED is true. HDR must have at least WIDTH, HEIGHT, GL-PIXEL-TYPE and DATA values specified. If GL-PIXEL-TYPE is :FLOAT, DATA should be a vector of R,G,B values. Otherwise, DATA is assumed to be a vector of RGB9-E5 values.
Write HDR to (UNSIGNED-BYTE 8) output stream STREAM, with ’new rle’ compression unless UNCOMPRESSED is true. HDR must have at least WIDTH, HEIGHT, GL-PIXEL-TYPE and DATA values specified. If GL-PIXEL-TYPE is :FLOAT, DATA should be a vector of R,G,B values. Otherwise, DATA is assumed to be a vector of RGB9-E5 values.
