Hidden text is computer text that is displayed in such a way as to be invisible or unreadable. Hidden text is most commonly achieved by setting the font colour to the same colour as the background, rendering the text invisible unless the user highlights it. Hidden text can serve several purposes.
Reminding others of Wikipedia policies where they have been frequently broken. For example, in many articles, hidden text is necessary to remind editors not to add inappropriate links. On the page Help:Getting started, hidden text is used to let others know not to write their first article on that page.
It used lines and bézier curves to render infinitely scalable graphics. [3] [4] Illustrator was released in early 1987, [5] and became a commercialization of Adobe's in-house font development software and PostScript file format. Adobe Illustrator is the companion product of Adobe Photoshop.
Sometimes, you find a drawing or similar image useful for a Wikipedia article, that was saved as a JPEG but should have been saved as a PNG.JPEG is good for images where the color changes fluidly throughout the image, like in a photograph, whereas PNG files are good for images with relatively few colors, such as a drawing of a flag, a chart, or a map; note that sometimes SVG is better.
ISO symbol for soft hyphen. In computing and typesetting, a soft hyphen (Unicode U+00AD SOFT HYPHEN (­)) or syllable hyphen, is a code point reserved in some coded character sets for the purpose of breaking words across lines by inserting visible hyphens if they fall on the line end but remain invisible within the line.
The illustration has a few geometric shapes and a lot of text; it was relatively easy to convert the shapes, and the SVG vector format allows the text (even subscripts and superscripts) to be entered easily. The original image did not have any curves (except for the text), so the conversion is straightforward.
In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.
PNG is a raster graphics format. PNG has advantages over SVG including smaller filesize (due to less-than-optimal server-side SVG-to-raster conversion), more widely supported and often easier and faster to make simple changes to things such as borders.
