GBMV - A bitmap viewer for OS/2 and eComStation

Introduction

GBMV is a fast and simple bitmap viewer for the OS/2 and eComStation Presentation Manager. It directly uses GBM.DLL and thus can show all bitmap file formats supported by it.

Bitmaps will be show in original size only. Zooming in or out is not yet supported. GBMV can use error-diffusion or halftoning to improve the quality of image display.
