Mixing Rules

IPDS allows the same physical pel to be overwritten an unlimited number of times. Overwriting can occur
both within a block and across blocks. For example, within text blocks, overwriting can be caused by using
the Overstrike control. Within a graphics block, overwriting occurs whenever one graphics area or figure
overlays another. Across block overwriting can occur whenever one IPDS block physically overlays any
portion of another IPDS block.
Within each block, the S828 IPDS Printer further defines background pels and foreground pels. Foreground
