It is often very useful to use this feature if you are drawing a symmetrical diagram. Draw the left hand side, join the individual parts together, copy and paste the image, flip horizontally, then align and join. Hey presto! A perfectly symmetrical object. The align objects option allows you to precisely align two or more objects together.

The fix is to open the SVG file in a text editor, find the <image> element, locate "image/jpg", change it to "image/jpeg" and re-save. At right is an example of this problem. The Commons SVG Checker looks for this problem; see Commons:Commons:Commons SVG Checker/KnownBugs#Checks for details.
The quality of GIF images is better than JPEG. GIF images allow for the creation of animations. PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours. As a pixel-based image, it is more difficult than an SVG image to edit. Some uploaders prefer to work with SVG and then upload a ...
An extension to the original algorithm called the midpoint circle algorithm may be used for drawing circles. While algorithms such as Wu's algorithm are also frequently used in modern computer graphics because they can support antialiasing , Bresenham's line algorithm is still important because of its speed and simplicity.
The image circle is the cross section of the cone of light transmitted by a lens or series of lenses onto the image plane. When this light strikes a perpendicular target such as photographic film or a digital camera sensor, it forms a circle of light – the image circle. Various sensor aspect ratios may be used which all fit inside the same ...
A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.
Image using width upright=1.8, so that it is 80% wider than the Siberian Husky image above (which is at the default upright=1 width) Image using upright=0.5; a scaling factor less than 1 contracts the image width. An image's size is controlled by changing its width – after which software automatically adjusts height in proportion.
