This Floyd-Steinberg dithering engine takes into account the gamma characteristics of the monitor and uses 768 KiB of dithering tables to avoid time expensive calculations. Then the data are passed through high-performance restartable dithering engine which is used regardless of monitor bit depth, i.e., also for 24 bits per pixel colour. This allowed Links to have anti-aliased fonts at a time when anti-aliased font libraries were uncommon.Īll graphic elements (images and text) are first converted from given gamma space (according to known or assumed gamma information in PNG, JPEG etc.) through known user gamma setting into a 48 bits per pixel photometrically linear space where they are resampled with bilinear resampling to the target size, possibly taking aspect ratio correction into account. Subpixel sampling further increases legibility on LCD displays. The fonts are anti-aliased without hinting and for small line pitch an artificial sharpening is employed to increase legibility. However this increases the size of the executable to about 5 MB. This allows the browser to be one executable file independent of the system libraries. The fonts displayed by Links are not derived from the system, but compiled into the binary as grayscale bitmaps in Portable Network Graphics (PNG) format. The graphics stack has several peculiarities unusual for a web browser. ( January 2010) (Learn how and when to remove this template message) Unsourced material may be challenged and removed.

The graphical mode works even on Unix systems without the X Window System or any other window environment, using either SVGALib or the framebuffer of the system's graphics card. The resulting browser is very fast, but it does not display many pages as they were intended. His group Twibright Labs later developed version 2 of the Links browser, that displays graphics, renders fonts in different sizes (with spatial anti-aliasing), but does not support JavaScript any more (it used to, up to version 2.1pre28). The original version of Links was developed by Mikuláš Patočka in the Czech Republic. It is intended for users who want to retain many typical elements of graphical user interfaces (pop-up windows, menus etc.) in a text-only environment. It renders complex pages, has partial HTML 4.0 support (including tables and frames and support for multiple character sets such as UTF-8), supports color and monochrome terminals and allows horizontal scrolling. Links is an open source text and graphic web browser with a pull-down menu system. Windows, macOS, OS/2, Unix-like, OpenVMS, DOS
