[gxnet]: grid types

[skyhunter]

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.     Aaron Balasch Sky Hunter Technologies Inc.
