GBM plugin for Netscape/Mozilla/Firefox/SeaMonkey

Introduction

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

For being able to use it, the following additional files are required:

Note:
GBM.DLL version 1.41 must not be used as it contains a compiler optimization issue that reduces stability. When used together with the GBM plugin, the browser might crash when opening bitmaps. Please upgrade to GBM.DLL version 1.42 or higher.

Note:
This plugin requires so far that the browser cache is enabled. Further version might be able to directly stream the images into the system memory.


Supported features

There is the embedded mode with reduced functionality and the fullscreen mode with full functionality.

Installing GBM for Netscape/Mozilla/Firefox/SeaMonkey

Simply copy npgbm.dll into the plugin directory of your browser. Please check the requirements listed for gbm.dll above. Copy gbm.dll either into the plugin installation directory beside npgbm.dll or put it somewhere in your LIBPATH (defined in CONFIG.SYS).

The plugin will try to use the GBM File Dialog if it is found somewhere in the LIBPATH. If it is not found, the standard OS/2 file dialog will be used. Save options for bitmap export cannot be specified in the OS/2 file dialog and thus the plugin will use the default export options of each bitmap format.

Note:
If you are using Rich Walsh's RUN! or LIBPATHSTRICT, the plugin will not work without some additonal effort from you. Simply copy gbm.dll into the browser installation directory (beside the .exe) or beside the plugin DLL npgbm.dll. This does not work with gbmdlg.dll. I have not found a way to get the GBM File Dialog loaded with LIBPATHSTRICT enabled without having to rewrite large parts of it. I'll not do this until I have a need for it. You'll have to stick with the OS/2 standard file dialog or don't use LIBPATHSTRICT.
