Aaron,
When
you open the grid, normally using CreateOutFile_IMG, name the grid as
follows:
my_new_grid.grd(GRD;Type=color)
The
part in brackets is called the name "decoration", and it is used to specify
certain grid characteristics, in this case to create a colour grid. See
.../etc/dat_xgd.doc for a full listing of the available decorations for
different grid types. You can also determine the correct decoration by
selecting an output grid using any GX that writes grids. When you browse
for a grid name, choose the "Save as type" to be what you want. The correct
decoration will be added to your grid name.

Hi,
Does anyone know how one can specify a grid image
in a GX to be created as a compressed colour grid?
I have a GX that I wrote where I am doing
a Math expression with DoFormula_ IEXP() operation on two existing
compressed colour grids. I want the output grid also to be a compressed colour
grid. Near as I can figure out, the grid type is defined
in CreateFile_IMG() but I do not know what define it as.
Trying to solve the problem, I went into look at
PREDEF_ALL.GXH. I found DATA_TYPE_COLOUR so I tried this but it gave an
invalid data type error. I also tried DATA_TYPE_DOUBLE(although it wouldn't
solve my problem) and that did not work either. Can anyone help?
In case it's aversion compatibility problem, I am
using version 5.1.5(OX) and I am up to date according to my software
manager.
