It is one of the widely used file type for creating tests for IT certification. If you have prepared for any certification I am quite certain that you would have come across this file format.
Raw RGB DataMany of the image file formats have particularities which you need to keep in mind when using that format. This page deals with these special needs, and ways to improve results in those formats. GIF This format is extremely common, and has been around for so long that all image handling programs understand it.
But only uses a limited number of colors a color table and only saves using 8 bit quality. However its built-in run-length encoding allows it to save images with only a few colors very efficiently.
Plain text with thin lines suffers badly when saved as a transparent GIF image.
The only solution to this problem is to tie the GIF image to a specific background of the web page in which it is used. The GIF format can save multiple images to form an animation sequence, and for this purpose also saves the image canvas size and offset page information.
Note however that negative offsets are not supported, and attempts to do so resets that offset to zero. Its best used for small images of cartoons, line drawings, and small icons, all of which have limited colors, and will allow it to compress well.
Its use however should be avoided when a newer format like PNG is available. JPEG Does not handle transparency at all. It is well suited to long term storage of real life photographs, but avoid it if you plan to further process the image, or the image contains large areas of solid colors.
It is a modern format capable of handling 16 bit quality with four color channels allowing the full use of semi-transparent colors. It also includes a huge number of lossless image compression options. Its biggest disadvantage is that it is still relatively new, such that the Microsoft IE v6 web browser does not automatically handle it correctly.
However a fix is available for this problem. The format does not save canvas size information where GIF doesbut it does save the canvas offsets and even negative offsets which GIF does notthough some web browsers have problems when a negative offset is used, so this is not recommended for a final image to be displayed in a browser.
A simple example of using MNG is wanted, so if you have one mail me. The MNG animation format appears to becomeing obsolete and has been abandoned by some web broswers such as FireFox. TIFF This is the Image interchange format that was developed to transfer high quality images between programs before any serious image formats were available.
Unfortunately, because of this beginning, the format has been modified with a haphazard array of features and compression styles and no programs understands them all.
The format is now pretty well only use by " Photoshop " on windows platforms, and this is the only source that provides any sort of standard reference for the TIFF image format. Generally, unless the internal format of the TIFF image is kept relatively basic, there is no guarantee that a TIFF file generated by one program will be usable by another program, including IM or even " Photoshop " itself.
As such I do not recommend this format period! Video Formats Other movie quality animation formats generally based on using lossy compression to reduce the size and quality of the movie.
Both formats are in a constant state of flux, improvements and security limiting features, making any form of processing difficult. Because of this IM does not directly handle this format, instead it relies on other software packages, to handling the processing of the individual frames into and out of the animations.
Some system like ubuntu disable the use specific image file formats using a security policy. Type convert -list policy to see what policies and where they are set from are present on your system. It is often picked for images which are to be displayed on web pages that involve transparency or image animation.
It is also about the only format absolutely universally understood by all web browsers. Unfortunately it is not a very good format for anything but line drawings, figures, diagrams, and cartoons. That is because it is limited to a maximum of colors, one of which is usually flagged as being transparent.
Flagging one specific color in the image as transparent has some drawbacks. If the color to use as transparent is badly chosen, it can result in other parts of the image being transparent when that was not intended. Care must be taken to ensure that does not happen.
Semi-transparent colors are just not possible, and if present need to be made either transparent or opaque. See Anti-Aliasing Because the "GIF" image formats color limitations causes so many problems, especially from a high quality image processing package like ImageMagick, I would like to say up front[Drawboard PDF PRO in-app subscription is optional].
