Dividing bitmap in two; odd / even line (interlaced) images?
Posted: 2010-08-31T08:50:40-07:00
Can ImageMagick divide an image into odd-line and even-line image files (interlaced) ?
Background
----------------
Basically I want to created odd and even interlace fields from a single image for the purpose of testing encoding techniques, encoding each field separately, then software deinterlacing to recombine the odd/even fields for subjective quality analysis of camera video. I want to decode and put the two fields back together and compare quality to the original. I could write a utility to split an image pretty quickly but every time I think about doing this I learn that ImageMagick already does this.
Thanks in advance for any examples or direction,

PS: I apologize if this appeared twice. I was having trouble joining the mailing list and then I re-discovered this server.
