GBM 1.51, GBM plugin 1.24 for Lucide RC1

January 24, 2007 by Heiko Nitzsche

GBM plugin 1.24 for Lucide RC1 or higher
(freely usable, see license included)

This is a plugin for the Lucide document viewer available for eComStation that extends Lucide for the support of reading all bitmap formats supported by GBM.DLL. It requires GBM.DLL 1.35 or higher. GBM 1.51 is recommended. Do not use GBM 1.41 any longer.

Supported features:
* document info
* loading all formats supported by GBM
* save loaded bitmap if it has only one page
* multipage bitmap viewing support
* load bitmap page on demand
* scaling and rotation

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

The above plugin does not work anymore with Lucide Beta 4 because the plugin API has changed. If you just upgrade your Lucide installation to RC1, please delete the old lugbm.dll or/and lugbm_b4.dll and install the new plugin. Users who want to stick with Lucide Beta 4 for the moment
can download a compatible plugin version from for a limited time.

For more details please have a look at the change log in the included documentation or at my GBM homepage (see below).

GBM.DLL 1.51 and GBM command line tools
(Public Domain)

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.

In this version, extended BMP, JPG, PNG, TIF, PBM, PGM, PPM, PNM and XPM support is additionally included. PNG and TIF support also 16, 32, 48, 64 bpp colour depths with/without alpha channel. PPM supports also 48 bpp colour depth. BMP supports also OS/2 RLE24 and Windows 16/32 bpp RGB and BITFIELDS formats.

It comes with a useful set of command line bitmap manipulation tools.

Get package from Hobbes.
It is also included in the WarpIN installation package (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 (1.51). Please follow the instructions to use the new GBM.DLL for all programs as well as for eCS WPS features like bitmap previews.
If you cannot replace the eCS shipped GBM.DLL, please execute unlock x:os2dllgbm.dll from a command line. Then override the old GBM.DLL with the new one. Don't forget to reboot afterwards.

The homepage of GBM for OS/2 and eComStation

It provides:
- comprehensive documentation (also included in the download archives)
