It's free! News June 6 2003. The 1.2 version of GD Imager (first release) is available. You can download it here . Download You can download the GD Imager script. Click here to download (size 3.6K) . How to use Installation instructions: 1. Copy a file gd_imager.pl in directories in which execution of cgi scripts is authorized 2. Set to a file gd_imager.pl execution rights. For example by the command "chmod 755 gd_imager.pl" 3. Whether check up module GD if is not present establish its by the command "ppm install GD", from a command line Example of a call: http://www.site.com/cgi-bin/gd_imager.pl?img=/photo/1.jpg&width=150 img=/photo/1.jpg - specifies the initial image width=150 - specifies the resulting width of the image As a result of work of a script - the picture comes back, to make out a call on a site it is necessary as follows: 1. Opportunities of scaling Source image (example): Variants of a call: ?img =/photo/1.jpg&width=150 - for reception of images of the set width (150) Result image: ?img =/photo/1.jpg&height=200 - for reception of images of the set height (200) ?img =/photo/1.jpg&width=150&height=200 - for reception of images of height it is no more 200 and width no more than 150 2. Mounting of pictures with the set substrate Base image (example png): Variants of a call: Without direct indications of the sizes of the image ?img =/photo/1.jpg&base =/img/base.png - for imposing scaling images on a file a substrate /img/base.png. Result image: ?img =/photo/1.jpg&base =/img/base.png&border=5 - for imposing scaling images on a file a substrate /img/base.png, thus the image will be scaling for a space 5. Result image: With the indication of the size scaling images ?img =/photo/1.jpg&base =/img/base.png&width=100 - the image is scaled on width on 100 pixels and then imposed on a file/img/base.png Result image: With alignment ?img =/photo/1.jpg&base =/img/base.png&width=100&align=right - to scale, impose, level by a right edge Result image: With spaces ?img =... &base =... &width =... &align=right&dx=5 - to scale, impose, level by a right edge with a space 5 Result image: ?img =/photo/1.jpg&base =/img/base.png&width=100&height=120 - to scale the image that it was placed about a rectangular 100x120 pixels (a proportion are observed), to impose on a file /img/base.png ?img =... &base =... &width =... &align=right&dx=5 - - to scale to impose, level by a right edge with a space 5 The parameter "align" - operates alignment across. Allowable values left, right, center, by default - center The parameter "valign" - operates alignment on a vertical. Allowable values top, bottom, center, by default - center Result image (valign=top&dy=5): The parameter "border" - sets spaces (from two sides or from one of the sides, depending on modes of alignment) The parameter "dx" - sets a space across (from that side with which there is an alignment or concerning the center of the image if alignment on the center) The parameter "dy" - sets a space on a vertical, is similar "dx" 3. Use of files of a configuration It is possible to use config files, for the description of parameters. The example of parameters of a call: ?img=/photo/1.jpg&conf=../conf/img In a file ../conf/img (the way determinzting relative of a script directory) is the information on parameters of processing of the image. The example of contents of a file: width = 107 height = 103 base = "/i/base.png" dx = 6 dy = 11 Processing of images in cases of use of files of configurations is absolutely identical to the task of these parameters in a line of a call 4. Caching opportunity The caching opportunity can be included only from a file of a configuration. The parameter cash_dir sets a way to a cashe directory (for each of configuration files, it there should be a directory) The example of a configuration file: width = 107 height = 103 base = "/i/base.png" dx = 6 dy = 11 cash_dir = "../cash" The way to cache is set relating to an arrangement of a script gd_imager.pl Additional parameters cash_time - time of updating cache (in seconds). + Value by default - 86400 (day). cash_slash - sequence a symbol for replacement "/" in a name of a file at record in cache. Value by default - "--". ( /i/1.jpg -> --i--1.jpg ) The example of a configuration file: width = 107 height = 103 base = "/i/base.png" dx = 6 dy = 11 cash_dir = "../cash" cash_slash = "--" cash_time = 800 Examples www.dance.org.ua/photos - the example of the technology.
