GBM (Generalised Bitmap Module) updates

November 01, 2008 by Heiko Nitzsche

++ From the VOICE OS/2-eCS News Service http://www.os2voice.org ++

Heiko Nitzsche has released updates to the Generalized Bitmap Module (GBM) package.

GBM plugin 1.37 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_lu137_moz138_bin.zip or the WarpIN installation package from Hobbes (see below).

GBM plugin 1.38 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_lu137_moz138_bin.zip or the WarpIN installation package from Hobbes (see below).

GBM.DLL 1.62 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_162_bin.zip or the WarpIN installation package from Hobbes (see below).

Enhanced GBMV/GBMV2 Version 1.53
--------------------------------
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 gbmos2pm153_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 (1.62). 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:
-----------
NEW: Build support for Microsoft Visual C++ (Windows 32bit)
Supported targets (via makefile):
* GBM executables & DLL
* GBM test and demo file creator
* J2K_CODEC executables (OpenJPEG decoder and encoder)
* Binaries available on GBM homepage

NEW: Build support for Linux (32bit and 64bit)
Supported targets:
* GBM executables & shared lib
* GBM test and demo file creator
* J2K_CODEC executables (OpenJPEG decoder and encoder)
* Binaries available on GBM homepage

GBM.DLL 1.62
* JPEG codec:
- allow a broader range of DC table symbols in huffman decoder
to support loading of PhotoPaint created JPEGs
* TIFF codec:
- Fix: Use a temporary scanline buffer for writing palette bitmap
because otherwise the original bitmap data are modified. This
was the case for instance with the LZW compressor with horizontal
prediction.
* PNG codec:
- Update to Libpng 1.2.32
- add support for writing a comment

* Fix buffer overrun when parsing very long option strings

GBM command line tools 1.53,
GBM PM tools 1.53 (GBMV, GBMV2, GBMVFSA, GBMLOGO)
* The command line parser now additionally supports the following
file specification templates:
"filename"","options
"filename"",""options"
This should be hopefully work for all variants now.
""filename"{,opt}" does not work together when &, |,
are part of the filename because the shell will interprete them
as operators and cut the filename.
The old template will continue to work for backward compatibility
reasons but the tools will from now on recommend the new template

GBMV/GBMV2 1.53
* GBMV2:
- Added Shift+A keyboard shortcut to activate selection mode
- Reworked online help for more consistency, some corrections
- Fix: The online help and the menu for rotating was inconsistent
(not mathematical correct).
* Some correction for struct paddings for GCC builds

GBM File Dialog 1.53
* Add comment parameter for PNG export to the online help
* improve description of comment parameter in online help

GBM plugin for Netscape/Mozilla/Firefox/SeaMonkey (NPGBM.DLL version 1.38)
GBM for Lucide (LUGBM.DLL 1.37)
* Enforce struct padding to 4 byte for compiler independent compatibility
* Common dynamic DLL loaders for GBM.DLL & GBMDLG.DLL reworked
- GbmAccessor for GBM.DLL now also supports Windows

GBMRX.DLL 1.13, GBMDLGRX.DLL 1.04
* incorporate changes done during porting GBM to Windows & Linux

For more details see the change log in the documentation.
