A ruler, sometimes called a rule or line gauge, is a device used in geometry, technical drawing, engineering and building to rule straight lines. Engineering designers used (before the advent of CAD) devices with graduations marked on their edge called scales, when setting out or measuring length on a drawing. They did not draw lines with their scales, they used set or T squares when ruling a line.

Rulers have long been made from different materials and in a wide range of sizes. Some are wooden. Plastics have also been used since they were invented; they can be molded with length markings instead of being scribed. Metal is used for more durable rulers for use in the workshop; sometimes a metal edge is embedded into a wooden desk ruler to preserve the edge when used for straight-line cutting. 12 in or 30 cm in length is useful for a ruler to be kept on a desk to help in drawing. Shorter rulers are convenient for keeping in a pocket. Longer rulers, e.g., 18 in (46 cm) are necessary in some cases. Rigid wooden or plastic yardsticks, 1 yard long, and meter sticks, 1 meter long, are also used. Classically, long measuring rods were used vt|for larger projects, now superseded by tape measure or laser rangefinders.

Advantages of Ruler PNG Format

    • Higher bit depths (more colors) PNG allows for 1, 2, 4, 8, 16, 24 and 32 bit images, smashing the 8-bit barrier
    • A permanent, royalty-free license PNG is being developed by the W3C, and will always be a free and open standard
    • Multiple layers of transparency Ruler PNG images allow for full alpha channel transparency, which makes moving images from one background to another easy.
    • Uses a lossless image compression technique, hence no information is lost and the image is retrieved keeping the same quality.
    • Supports all the true colors, unlike the contemporary GIF format which only supports 256 colors.
    • Alpha channel support in PNG images allows transparency of the file format which is not possible with other file formats.
