![]() ![]() Most modern image editing tools are able to read both. Own formats, both of which are called BMP. There are actually several BMP formats (BitMaP). ![]() Vector Magic recommends using the PNG format when storing logos as bitmaps. This format is widely supported by web browsers and image viewers/editors. The best of the lossless image formats is called PNG (Portable Network Graphics). They are more suitable for things like logos. These store an exact pixel-by-pixel representation of the image, but require more space. We do not recommend using JPEG files for rasterized vector art, as the compression artifacts substantially degrade the quality of the image near edges. It has excellent compression characteristics and has the nice feature that the user may specify what level of compression they desire, trading off fidelity for file size. One of the most widely-used image formats. They are also commonly used on the web to save bandwidth. They are best suited to photographs and other images where perfect accuracy is not important. These have smaller file sizes but do not store a perfect copy of the image. Some of the most common are: JPEG, PNG, GIF, BMP, and TIFF.īroadly speaking, they fall into two categories: Lossy formats CC BY-SA 3.0 Creative Commons Attribution-Share Alike 3.There is a large number of different bitmap formats.

Note how the view of spacetime changes when the observer accelerates. The slope of the world line (deviation from being vertical) gives the relative velocity to the observer. The events passing the two diagonal lines in the lower half of the picture (the past light cone of the observer) are those that are visible to the observer. The small dots are arbitrary events in spacetime that are stationary relative to each other. ![]() In this animation, the vertical direction indicates time and the horizontal direction indicates distance, the dashed line is the spacetime trajectory ("world line") of an accelerating observer.
