Take a look at the supplied screenshot, or try it yourself. How do I know if I have ImageMagick installed? How do I install ImageMagick? I get a fatal error when activating plugin Some webhosts 1and1 for example need to add a work-around to the.
You might have to add the following line to your. The thumbnail regeneration could be a bit faster though. I have used it for longer than I can remember, at least 5 years. This is the first review i have ever left for any plugin. For example This is only a small sample of what is available. Huge libraries of just about every symbol, shape, or image, imaginable is available on the WWW for you to browse and download. Remember that each drawn character has two separate parts that can be drawn: the 'filled' area which I showed above , and the 'stroke' or outline, which can look very different to the filled area.
Each of these areas can be drawn separately, or in different colors, so it may be a good idea to examine a promising symbol or shape more closely, in a number of ways. You may get a very surprising result. See Compound Fonts, Stroke for some examples of doing this.
Many creators of symbol fonts generate the shapes using a simple scanner and bitmap to vector converter, without any proper design or cleaning of the image or shape. Caution is recommended when looking at such 'scanned' fonts. The last font shown above is one such example of a 'scanned' font, giving it a poor looking 'dotty' quality, when compared to the other more properly designed fonts.
Type convert -list policy to see what policies and where they are set from are present on your system. This was one of the reasons the " -annotate " operator was created for IM version 6. Protecting input text file from escape handling was finalised in IM version 6.
Before IM version 6. In that case the only way to escape an initial ' ' was to read it from a file. This was not very practical in API's. IM v6. However they returned in IM v6. See FX Expression Escapes. On systems with pango installed you can also use the command " pango-view " for generate pango formated images.
However its default 'density' or 'dpi' setting is your display IM uses 72 dpi by default and as such may vary from host to host. Do not confuse the " text: " file input format with the similar " txt: " input format. The latter will first attempt to read the file as a ' IM pixel enumeration ' image format.
That doesn't mean that a plain text file with a ". In fact such a file will probably be converted as you would expect, as the " txt: " file format will automatically fall back to the " text: " format if an enumerated image is not recognised. The input text data read from the file is essentially passed directly to the font library to draw the UTF text. As a consequence of this some control characters may be drawn using unusual 'glyphs'. In all these examples, selecting the output image should let you download the image which was actually created by the example command.
But be warned, not all browsers understand all image formats used. External Image Sources By the way, most of the source images used in these examples come from Anthony's Icon Library , particularly the background tiles , large clip-art , and dragons sections of the library.
I like dragons! ASIDE: these pages may be offline as the web site slowly moves to a new server. This library actually predates the WWW. I created it in , due to the lack of good, clean iconic images for use on the X Window System. The advent of the WWW has of course changed this, but my original library still exists and remains available as a source of images, even though it is not actively growing.
Some specific images, and larger images, are contributed by the authors of specific examples. The authors of such examples are listed in the contributed section, or at the bottom of the page.
If you are looking for a specific image, I recommend using Google Image Search or similar to find something appropriate. You can, of course, convert or resize such images using IM for your own purposes. However, you should be careful about copyright if you plan to use such images commercially.
The PNG image format supports images with semi-transparent pixels, a feature few other image formats provide. It is also a very well-understood image format and, as such, is usable by most of today's image programs and Web browsers. Technically, this is only problem with IE, not ImageMagick. Displaying Images on Your Screen Display problems can also occur when displaying images on-screen. Because of this, I recommend using a command like the following to tile a ' checkerboard ' pattern underneath the image, to highlight any transparent or semi-transparent pixels in it.
Normally, the command would output the results to your display, not onto a Web page like this. If you look carefully, you can see the checkerboard pattern though the semi-transparent colors. However, the image, as a whole, is fully opaque. So, this technique should work on all displays, Web browsers, and image viewers. As of IM v6. However, it does not seem to handle images using color tables i. Using the " x: " output image format as above causes an image to be displayed directly to the screen, without having to save it.
See Show Output Display for more information. Font Usage The fonts I use in these examples are from a small collection of TrueType fonts I have found over the years, and saved for my own use. Some of these are under copyright, so I cannot publish them online.
You are, however, welcome to substitute other fonts that you have available. The examples should work perhaps with some changes to image size with any appropriate font you have available on your system.
Microsoft "Arial" font, or even "Times-BoldItalic", should work on most systems. To see what fonts are currently available to your version of IM, run the following command To activate the use of diffutils within MediaWiki, you have to ignore the fact that they won't be found during installation they may actually be found if you install diff into your path and open up LocalSettings.
The "Q8" ImageMagick releases use 8 bits per channel, while the "Q16" releases use 16 bits per channel. Here is the download page for ImageMagick on Windows. Without this you might see an PHP shell execution error similar to what happens when it can't find the convert.
