[gradsusr] Memory Allocation Error When Using PRINTIM

[Huddleston, John]

Stephen,

A question: if you reboot the XP box can you repeat the memory allocation error? When you do it, start task manager and watch the Performance TAB memory usage.

Subject: [gradsusr] Memory Allocation Error When Using PRINTIM

I believe this is the first time I've encountered this error in 7+ years of using GrADS, and could not find anything specific to this in the User Archives:

ga-> printim c:\temp\uscan.map.png x960 y720 white
Memory allocation error: gxhpng

I executed above  "printim" at the command line after creating a test background map using various shapefiles and the shp_polyf/shp_lines commands.  No file was generated.  However, I do not get the error when using "gxyat..." to create it, such as the file attached.

At the time of execution, I had an OPeNDAP connection to the latest operational GFS forecast model at NOMADS.  Just prior to using the shapefile commands, I had displayed a single variable to set the map environment, and there were no defined variables.  The .shp files I used ranged between 1 and 13MB size.

I'm using GrADS 2.0.a7.oga.3 on a 3-4 years old Windows XP, with 3.2GB RAM.  I have not yet tried this with the later opengrads or cola versions.
