Frame Range, FRS |
range = FRS( nFrameOffset AS INTEGER, nFrames AS INTEGER ) AS INTEGER
Returns the a range of frames.. The range is specified as offset and number of frames. This can be used by any MAL function that can use frame offset as argument. If the nFrames is 0, then all frames are used.
Techincal Description
The function creates a 32 bit integer where the lower 18 bits defines the frame offset (max 262,143) and the upper 14 bits defines the number of frames (max 16,383).
Example:
' Calculate Verctor length of Point 2 from frame 11 through 100 DIM r AS REFERENCE r = MAL.VectorLength( NULL, arrPoints, 2, FRS( 10, 90 ) ) CALL PrintArray( r ) UNREF r
