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.
In HTML and XHTML, an image map is a list of coordinates relating to a specific image, created in order to hyperlink areas of the image to different destinations (as opposed to a normal image link, in which the entire area of the image links to a single destination). For example, a map of the world may have each country hyperlinked to further ...
The JPEG (Joint Photographic Experts Group) format can produce a smaller file than PNG for photographic (and photo-like) images, since JPEG uses a lossy encoding method specifically designed for photographic image data, which is typically dominated by soft, low-contrast transitions, and an amount of noise or similar irregular structures.
JPEG compression works better on slightly blurred images, so don't sharpen the images too much as it will result in a higher footprint. Always work from the original image and not from the already saved JPEG file, as quality gradually decreases the more you save it; this is known as digital generation loss .
ACDSee Pro can read and write XMP information for DNG, GIF, JPEG, PNG and TIFF files (Microsoft Windows, Mac OS X). Acrobat - can read and write XMP in PDF files (Microsoft Windows, Mac OS X, partially Linux). Aperture - Image management application and RAW developer. Reads/writes XMP sidecar files to (batch) import/export image metadata (Mac ...
In this example, the image data is encoded with utf8 and hence the image data can broken into multiple lines for easy reading. Single quote has to be used in the SVG data as double quote is used for encapsulating the image source. A favicon can also be made with utf8 encoding and SVG data which has to appear in the 'head' section of the HTML:
As described in the image map documentation, regions can be specified as circles, rectangles, and arbitrary polygons, and the blue "i" icon can be moved or suppressed. Also, the image can be specified as a thumb or frame, which means it has alt text and a caption in the usual way, with a double-rectangle icon instead of the blue "i" icon .
Alternate text is optional but recommended. See Alternate text for images for hints on writing good alternate text. To have some text to the left of an image, and then some more text below the image, then put in a single <br clear="all">. This will force following text down until the margins are free of floating images.
