About formats

ICO is the icon file format for Microsoft Windows), introduced with Windows 1.0 in 1985 and serving as the standard container for application icons, file type icons, and shortcut icons throughout the Windows ecosystem. An ICO file bundles multiple image variants within a single container — each at different sizes (16x16, 32x32, 48x48, 256x256, and others) and color depths (4-bit, 8-bit, 24-bit, 32-bit with alpha) — allowing Windows to select the most appropriate image for each display context, from tiny taskbar buttons to large desktop icons. The container structure consists of an ICONDIR header, an array of ICONDIRENTRY records describing each variant, and the image data itself. Since Windows Vista, ICO files support embedded PNG-compressed images for the larger sizes (typically 256x256), dramatically reducing file size while maintaining quality with full alpha transparency. One advantage is automatic size adaptation — Windows pulls the optimal resolution from the ICO container for each context (Explorer list view, desktop tile, Alt-Tab preview), ensuring crisp display without the application managing separate image files. The format's operating system-level integration is another core strength: ICO files serve as the identity mechanism for executables, file associations, and shortcuts across all Windows versions, and web browsers use favicon.ico for website identity in tabs and bookmarks. ICO creation and editing is supported by image editors like GIMP, Inkscape, and dedicated icon tools, and the format remains essential for Windows application development.

PCD (Photo CD) is a proprietary image format developed by Eastman Kodak in partnership with Philips, launched in 1992 as a system for transferring 35mm film photographs to compact discs for digital viewing and printing. Each PCD file stores a single photograph at five different resolutions in a hierarchical structure called an Image Pac: Base/16 (192x128), Base/4 (384x256), Base (768x512), 4Base (1536x1024), and 16Base (3072x2048), with optional 64Base (6144x4096) on Pro Photo CD discs. Images are stored in Kodak's proprietary YCC color space (a variant of CIE Lab via the Photo YCC color model), which captures a wider gamut than sRGB, at 8 bits per component in the luminance channel and subsampled chrominance. The multi-resolution pyramid is encoded using a progressive scheme: the Base image is stored directly, and each higher resolution is stored as a residual (difference) that refines the upscaled previous level, keeping the total file size manageable. One advantage is the exceptional scan quality: Photo CD scans were performed on Kodak's professional PIW (Photo Imaging Workstation) scanners by trained operators, producing consistently excellent results from 35mm negatives and slides — often better than what contemporary consumer flatbed scanners could achieve. The multi-resolution structure is another notable feature: a single PCD file serves needs from thumbnail browsing to high-resolution printing without separate file versions. PCD files can be read by Adobe Photoshop, ImageMagick, GIMP (via plugin), IrfanView, and XnView, ensuring continued access to the millions of Photo CD images created during the format's commercial peak in the 1990s.
