GBM 1.37, GBMV2 1.24, GBM File Dialog

March 30, 2006 by Heiko Nitzsche

GBM.DLL 1.37 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 PNG, TIF and PPM support is additionally included. PNG and TIF support also 32, 48, 64 bpp colour depths with/without alpha channel. PPM supports also 48 bpp colour depth.

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

Get package gbmos2_137_bin.zip from Hobbes.
It is also included in the WarpIN installation package (see below).


Enhanced GBMV2 Version 1.24
---------------------------
(Public Domain)

GBMV2 is a fast and simple bitmap viewer and editor for the
OS/2 Presentation Manager.

Enhanced release of the GBMV2-Viewer from the GBMOS2PM package:
* An English and a German version of GBMV2 is included.
* An English and a German version of the GBM file dialog is included.

GBMDLG.DLL has been extended by:
* Bitmap preview within the file dialog
* Redesign to fit eComStation file dialog style

Both parts got new resources that better fit to the Warp 4
and eComStation look & feel. The package comes with resources
for fonts 8.Helv and 9.WarpSans for both, German and English.
Several extensions for keyboard shortcuts have been added.

Get package gbmos2pm124_bin.zip from Hobbes.
It is also included in the WarpIN installation package (see below).


The new homepage of GBM for OS/2 and eCS
----------------------------------------
http://heikon.home.tlink.de

It provides:
- reworked documentation (now also included in the download archives)
- developer tutorials on how to use GBM libs in your own programs
(work in progress)
- download of all sources and binaries
- change log


What's new compared to GBM.DLL 1.36 and GBMV2 1.23
--------------------------------------------------
GBM.DLL 1.37:
* Some small performance optimizations for color mapping in TIF, PNG and PPM when importing/exporting.

GBM File Dialog 1.24:
* Bitmap preview enhanced
If options are entered into options field and the field loses focus, they are now interpreted for the preview. ext_bpp is supported as well but because OS/2-PM only supports 24 bpp the bitmap is downsampled for the preview.
* Bitmap info beside preview image extended to show also number of contained pages if a recent GBM.DLL is found.
* Fix dialog resource issue with IBM RC compiler (get rid of CTLDATA at VALUESET) which caused a crash with IBM VAC compiled GBMDLG.DLL. OpenWatcom wrc didn't cause any issues.

The WarpIN installation archive has been revised to reduce the download size. Please uninstall all versions before 1.36/1.23 first, then install.

All binaries are optimized for Pentium or compatible processors but
they should run on earlier 32bit processors as well (untested).

Have fun,
