'''Stop Press Canvas''' (extension '''.spc''') is an uncompressed fixed-size raster image format, originally associated with the Stop Press graphics package for Amstrad PCW computers.<br />
<br />
== Format description ==<br />
<br />
From [[User:John e|John Elliott]]'s SPC2BMP source code (August 1996; no longer online?):<br />
<br />
: SPC format:<br />
: SPC describes a black-and-white picture, 720 pixels across by 256 down. The aspect ratio is similar to the 640x200 CGA mode. The file is stored as 32 blocks of 720 bytes.<br />
: Within each block, eight lines are stored, interleaved. The top line is in bytes 0,8,16,...; the second in bytes 1,9,17,... and so on. <br />
: SPC files work from top to bottom and left to right.<br />
<br />
(This is essentially the [https://github.com/Zigazou/amstrad-pcw-technical-info/blob/master/video-memory/README.md in-memory format of the PCW screen].)<br />
