GBM.DLL 1.54 and GBM command line tools
The Generalised Bitmap Module (GBM) is a library capable of loading and
saving bitmap files in a variety of popular and less popular bitmap file
formats. Programs may be written to use this code, and thus be able to
access a variety of file formats without actually knowing what format
the pictures are in, or any details about file format itself.
It comes with a useful set of command line bitmap manipulation tools.

Get package or the WarpIN installation package
from Hobbes (see below).

GBM.DLL REXX adapter library (GBMRX 1.10)
GBMRX.DLL 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.
Now some image manipulations can be done like scale, reflect, rotate.

Get package from Hobbes.
It is also included in the WarpIN installation package (see below).

Enhanced GBMV/GBMV2 Version 1.42
GBMV2 is a fast and simple bitmap viewer and editor for the
OS/2 and eCS Presentation Manager. GBMV is a simple bitmap viewer.

Get package or the WarpIN installation package
from Hobbes (see below).

Notes for eComStation 1.2/1.2R users:
Please read the installation instructions. eCS 1.2/1.2R ships with an
old GBM.DLL (1.12) which prevents loading of the new GBM.DLL (1.54).
Please follow the instructions to use the new GBM.DLL for all programs
as well as for eCS WPS features like bitmap previews.
