Hi,

there are new versions of the GBM modules available.

GBM plugin 1.33 for Lucide 1.20
-------------------------------
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.

Get package gbmos2plugins_lu133_moz134_bin.zip or the WarpIN installation
package from Hobbes (see below).

GBM plugin 1.34 for Netscape/Mozilla/Firefox/SeaMonkey
------------------------------------------------------
This is a plugin for the Webbrowsers Netscape, Mozilla, Firefox and
SeaMonkey available for OS/2 and eComStation that extends them for the
support of reading all bitmap formats supported by GBM.DLL.

Get package gbmos2plugins_lu133_moz134_bin.zip or the WarpIN installation
package from Hobbes (see below).

GBM.DLL 1.55 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 gbmos2_155_bin.zip or the WarpIN installation package from
Hobbes (see below).

GBM.DLL REXX adapter library (GBMRX 1.11)
-----------------------------------------
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.
Some image manipulations can be done like scale, reflect, rotate.

Get package gbmos2rx111_bin.zip from Hobbes.
It is also included in the WarpIN installation package (see below).

Enhanced GBMV/GBMV2 Version 1.50
--------------------------------
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 gbmos2pm150_bin.zip 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 (1.55). Please
follow the instructions to use the new GBM.DLL for all programs as well as
for eCS WPS features like bitmap previews.

What's new (highlights only):
-----------------------------
GBM.DLL 1.55
* PNG codec upgrade to Libpng 1.2.25
* Some minor fixes

GBM command line tools
* gbmsize: Removed maximum size limit

GBMV2 1.50
* Red Eye fix capability
* Some menu items to rearranged to better logical groups
* Maximum allowed size for resize increased to 15000x15000
* Main window pos/size last path in file open/save dialog is now sticky
across sessions
* Background colour is now dark gray to put the bitmap colours more to front
* Reduced memory consumption due to internal structural changes
* Several fixes (see history)

GBM plugin for Lucide (LUGBM.DLL 1.33),
GBM plugin for Netscape/Mozilla/Firefox/SeaMonkey (NPGBM.DLL 1.34)
* Reduced memory consumption
* Custom settings definable in lugbm.cfg (Lucide plugin) or npgbm.cfg
(Mozilla plugin) file
(so far
scaler={simple,nearestneighbor,bilinear,bell,bspline,mitchell,lanczos})
The default scaler is simple to allow fast scaling on less powerful systems.

All modules (also non-listed):
* Allocate from high memory if supported by the OS to stretch limit for
out-of-memory errors

For developers:
* New gbmmem.lib library used for platform independent memory management
- on OS/2 high memory objects are preferred for allocation
- Must be linked to all code that uses gbm code libs (e.g. gbmscale)

For more details see the change log in the documentation.

Have fun,
