SIMG — Set IMaGe model
Format
SIMG operation-mode;
Parameter
operation-mode:
Function
The SIMG command sets the mode for controlling the transparency and opaqueness of
an image and the current pattern when they are overlaid on each other.
In the table above, the source image can be a rectangular area, characters, or a raster
graphics image preceded by an SIMG command. The fill patterns and gray shade
rendered with the PAT (pattern), FPAT (fill pattern), and GPAT (gray pattern) commands
can be used for pattern images.
With operation modes 1 and 2, the SIMG command takes care of the source image’s
transparency only. The default operation mode is 1. The white pixels of the source image
do not overlay on the destination. For example, you cannot pattern a character. With
operation mode 2, the SIMG command applies the white pixels of the source image onto
the destination directly.
