Note: Updated Lurker's Guide available (but not this page!)

This page belongs to the old 1990s SGI Lurker's Guide. As of 2008, several of the Lurker's Guide pages have been updated for HDTV and for modern OS platforms like Windows and Mac. This particular page is not one of those, but you can see what new stuff is available here. Thanks!

Examples of Image Parameters in SGI Movie and Digital Media Libraries

Here are some examples which show the relationship between the memory location, spatial location, and temporal location of the lines of an image given different settings of the MV/DM parameters.

The examples were generated with the program imagelines.c, which you will recognize from the sample code in the document.

Parameters:
  • DM_IMAGE_ORIENTATION==DM_IMAGE_TOP_TO_BOTTOM
  • DM_IMAGE_INTERLACING==DM_IMAGE_INTERLACED_EVEN
Signal: 8-line interlaced signal (even frame parity)
Memory: split field representation with top-to-bottom orientation
