Technical Introduction: In the early dawn of desktop-oriented computing graphics, specialized raw raster standards were formulated. Among these systems, ICB (Internal Canvas Bitmap) and VST (Vista/Video System Targa) acted as critical elements. The ICB structure served mainly as an internal buffer storing temporary raster arrays directly in local system memory. However, preparing these arrays for display on specialized hardware devices like Truevision Vista display adapters required mapping them to the formal VST specification. The ICB to VST Online Converter by Vo Viet Hoang is designed to assist systems engineers, retro software developers, and archiving enthusiasts to automatically perform this structural transition, maintaining original pixel structures for legacy hardware emulation and deep data research.
The Structural Divergence: ICB vs VST Formats
Although both components technically align with the broader Targa raster family, ICB and VST configurations carry distinct differences regarding target hardware interfaces and metadata flags.
The ICB Layout - Minimalist Canvas Backing
ICB (Internal Canvas Bitmap) is designed primarily for raw speed, capturing local system operations as basic bitmap data. It does not carry extensive color maps, rendering instructions, or advanced hardware profile registers. Consequently, loading unmapped ICB files directly inside standard modern applications often results in parsing failures, requiring specialized mapping routines to translate the raw stream.
The VST Layout - Tailored for Vista Video Hardware
The VST configuration is formally specified for integration with Video System units. Crucially, the VST header dictates strict guidelines for color depth translation (8-bit, 16-bit, 24-bit, or 32-bit layouts). Transitioning from ICB to VST adds these missing parameters, allowing legacy simulators and early operating frameworks to successfully read and render graphic tables as intended.
