Quick Image Viewer Fast

A lightweight, ultra-fast Linux alternative to IrfanView for rapid image viewing,
lossless rotation/flip, quick color adjustments, multipage/panorama creation, and
batch conversion/renaming. Disclaimer: Independent open-source project, not

KEY FEATURES:
• Ultra-Fast Image Viewer & Live Pixel Inspector: Scans real Linux image directories in milliseconds via os.scandir (PNG, JPG, BMP, GIF, SVG, XPM, PPM, PGM, PBM, XBM) with Fit/100%/200%/400% pixel-grid zoom, keyboard navigation, live cursor coordinate + HEX/RGB inspector, and 1-click Rotate, Flip, Auto-Contrast, Grayscale, Invert, Sharpen, and Crop tools.
• Image Properties, Unique Color Counter, 256-Bin RGB Histogram & Panorama Stitcher: Computes exact pixel buffer metrics (W×H, Megapixels, Bit Depth, Alpha, Unique RGB Colors, Mean Luminance, Compression Ratio vs Raw RGB, SHA-256, MD5), plots a real 256-bin RGB + Luminance histogram, and stitches horizontal/vertical panorama strips.
• Irfan-Style Batch Conversion & Pattern Rename Engine: Batch converts, resizes (W×H or %), adds optional frame borders/text overlays, and renames real images with pattern masks (e.g. img_###) while verifying output sizes and SHA-256 digests.
