Hi,
there are new GBM updates available with many improvements.
GBM plugin 1.35 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_lu135_moz136_bin.zip or the WarpIN installation
package from Hobbes (see below).
GBM plugin 1.36 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_lu135_moz136_bin.zip or the WarpIN installation
package from Hobbes (see below).
GBM.DLL 1.60 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_160_bin.zip or the WarpIN installation package from
Hobbes (see below).
Enhanced GBMV/GBMV2 Version 1.51
--------------------------------
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 gbmos2pm151_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 (1.60). Please
follow the instructions to use the new GBM.DLL for all programs as well as
for eCS WPS features like bitmap previews.
The homepage of GBM for OS/2 and eComStation

What's new (highlights only):
-----------------------------
GBM.DLL 1.60:
* NEW: JPEG2000 Codec based on OpenJPEG 1.3+ (only for OpenWatcom builds)
* NEW: Build support for Windows with OpenWatcom
* FIX: Resolved problem with GBM_O_ and GBM_SEEK_ mode mapping for compilers
that start definitions at 0x0.
* PNG codec:
- upgrade to Libpng 1.2.31
- use high memory allocation via GBM memory handler
* JPG codec:
- use high memory allocation via GBM memory handler
- activate library defined code inlining
* TIFF codec:
- use high memory allocation via GBM memory handler
- activate library defined code inlining
- reject unsupport samplesPerPixel
(IBM TIFF seems to write buggy images for 32bpp which are marked
as graylevel image but has 4 samples per pixel)
* BMP codec:
- Add support for reading 16/32bpp BGR OS/2 1.2,1.2 bitmaps which
are written by some apps when graphics card runs at 16/32bpp.
* Many Makefile updates to support new build platforms
* API changes:
- Due to sync to official GBM sources, the old types BOOLEAN, byte, word
and dword are obsolete and should no longer be used. Replacements are
gbm_boolean, gbm_u8, gbm_u16, gbm_u32. This does not hurt binary
compatibility!
There is a fallback for clients, backward compatible types can be
activated
by defining OLD_GBM_TYPES. Please prefer switching to the new types.
GBMV/GBMV2 1.51
* Allow window positioning on non-byte aligned x coordinate
* Adjust worker thread priority to idle time to make the system more
responsible.
* Remember open/save format and path separately across sessions
GBM File Dialog 1.51
* Added JPEG2000 format to online help
* Some reformatting of the online help to make it more consistent
* Selection of a different file type automatically changes the filename
extension
GBM plugin for Netscape/Mozilla/Firefox/SeaMonkey (NPGBM.DLL version 1.36)
GBM for Lucide (LUGBM.DLL 1.35)
* JPEG2000 support (requires GBM.DLL 1.60 or higher)
* New user configurable background rendering (option
progressive_render_pages)
-> Improves page switching performance, especially when using high quality
scaler. On dual-core systems the performance gain will be much higher
than on single-core systems.
-> Always progressive_render_pages/2 pages backward and forward will
be calculated in background.
* For lengthy operations now the hourglas mouse pointer is shown
* The size and color depth of the current page is shown behind the format
name in the document information dialog
For more details see the change log in the documentation.
Have fun,
Heiko Nitzsche
