Eliminating Display Scaling Artifacts Across Monitors

Modern multi-monitor setups frequently mix 100%, 125%, 150%, 175%, and 200% DPI scaling factors. By packing all 6 standard resolutions (16, 32, 48, 64, 128, 256 px), Windows never has to interpolate between distant sizes, ensuring razor-sharp edges on every screen.

Binary Offset Optimization

Imgora calculates contiguous byte offsets in memory, ensuring the container remains compact (typically under 60 KB) while housing six distinct pixel buffers.
