SPRITEA_XReplication

Tag for AllocSpriteDataA() Controls the horizontal pixel replication factor used when converting the bitmap data. Default - 0

Declaration

Source position: agraphics.pas line 1806

const SPRITEA_XReplication = $81000002;

Description

Controls the horizontal pixel replication factor used when converting the bitmap data. Valid values are:

0: perform a 1 to 1 conversion
1: each pixel from the source is replicated twice in the output.
2: each pixel is replicated 4 times.
-1: skip every other pixel in the source bitmap
-2: only include every fourth pixel from the source.

This tag is useful for converting data from one resolution to another. For instance, hi-res bitmap data can be correctly converted for a lo-res sprite by using an x replication factor of -1. Defaults to 0.
