GBMRX is a REXX adapter DLL for OS/2 and eComStation which REXX programs may use to load or save all bitmap file formats supported by the GBM.DLL (to/from a file).
Almost full feature set of GBM.DLL is provided by the REXX API. I/O remapping is not supported due to language restrictions.
The library also provides some bitmap manipulation functions like scaling, reflecting, rotating and colour conversions. These operations are done in-memory on the bitmap data and require no temporary files.
For being able to use it, the following additional files are required:
Just unzip the GBMOS2 package and copy the gbm.dll
file into the same directory as gbmrx.dll
and add
this directory to the LIBPATH statement in CONFIG.SYS in case
it is not already in there.
