Palm Database
The generic database container for Palm OS.
PDB (Palm Database) is the standard file format for all data on Palm OS devices, from address books to e-books. In the context of images, a PDB file acts as a container for 'Palm Pixmap' images, typically storing them as a series of records. It was the only way to get data onto a Palm pilot.
A PDB file consists of a header (name, attributes, creation time) and a list of records. For images, these records contain the bitmap data (often compressed with RLE/PackBits). ImageMagick treats PDB files as a multi-image sequence if multiple bitmaps are stored in the records. The format is strictly structured to map directly to the device's RAM storage model.
Created by Palm Computing in 1996. It was designed to facilitate 'HotSync' between the handheld's RAM and the desktop PC. It became ubiquitous in the early 2000s PDA era.
SVG (Scalable Vector Graphics)
The web's standard for crisp, infinite-resolution graphics built with code.
SVG (Scalable Vector Graphics) is fundamentally different from other web image formats. Instead of storing a grid of pixels (raster), SVG stores mathematical instructions for drawing lines, curves, and shapes. This means an SVG image looks perfectly sharp whether it's displayed on a tiny smartwatch or a giant billboard. Developed by the W3C, SVG is an XML-based format, meaning the file itself is human-readable text code. This allows SVGs to be manipulated via CSS and JavaScript, making them interactive and dynamic. You can change the color of an icon on hover, animate a graph with data, or theme an entire illustration with a single line of CSS. Since its standardization in 1999 and widespread adoption in modern browsers, SVG has become the default choice for icons, logos, and simple illustrations on the web, offering smaller file sizes and better flexibility than their raster counterparts.
SVG is an application of XML (Extensible Markup Language). An SVG file contains elements like `<circle>`, `<rect>`, `<path>`, and `<text>` that describe the visual content. Because it is text-based, it compresses extremely well with GZIP or Brotli (often served as .svgz). The format supports gradients, patterns, clipping paths, and masks. It can embed raster images (like JPEGs) inside the vector file, though this negates the scalability benefits for that portion. SVG supports interactivity through event handlers (onclick, onhover) and animation via SMIL (Synchronized Multimedia Integration Language) or CSS/JavaScript. Security is a unique consideration for SVG: because it can contain scripts, SVGs from untrusted sources can pose XSS (Cross-Site Scripting) risks and must be sanitized before use.
In the late 1990s, the web needed a vector graphics format. Several companies submitted proposals to the W3C, including Adobe's PGML and Microsoft/Macromedia's VML. The W3C decided to develop a new standard that combined the best features of these proposals, resulting in SVG. SVG 1.0 became a W3C Recommendation in September 2001. However, browser support was initially poor, requiring plugins like Adobe SVG Viewer. Native support began to appear around 2005-2006 (Firefox 1.5, Opera 9) but didn't become universal until Internet Explorer 9 added support in 2011. The format has evolved with SVG 1.1 (2003) and the ongoing development of SVG 2, which aims to align closer with HTML5 and CSS3 features.
