OK, check out the attachment.
Let me explain the labels ~
Original= umm, the original pcx file in 8-bit format
1-A= 8-bit stretch of original to 176x211
1-B= 24-bit stretch of original to 176x211
2-A= 8-bit conversion of original using scalerx* (2) then stretched to 176x211
2-B= 24-bit conversion of original using scalerx (2) then stretched to 176x211
3-A= 8-bit conversion of original using scalerx (2x3) then shrunk to 176x211
3-B= 24-bit conversion of original using scalerx (2x3) then shrunk to 176x211
For each of the 24-bit conversions, color depth was set to 24-bits before resizing.
* using scalerx available from SourceForge, pointed out by Uatu in another thread here.
