I divide the graphics editing program into two categories: a (yes) drawing program, which allows you to draw images one pixel at a pixel (ground), and another (yes) charting program that provides a set of objects, such as lines, ellipses, and rectangles, that you can use to combine a large image, such as a JPEG. The drawing program is ideal for pixel-level control. But (yes) for business graphics, the Cartographic Program (IS) a better () way, because most of the graphs (are) consist of rectangles, lines, and ellipses.
PHP built-in () basic operations are very similar to drawing programs. They are very powerful for drawing images, but (yes) this is not appropriate if you want a collection of objects of your own (that is) an image. This article will show you how to build an object-oriented graphics library based on the PHP graphics library. You will use the object-oriented () extension provided in PHP V5.
With object-oriented graphics support, your () graphical code (on) is very easy to understand and maintain. You may also want to combine graphics into multiple types of media from a single, graphical Source: Flash movies, SVG, and more.
Goal
Creating a drawing Object library consists of 3 main () Goals:
Switch from basic operation to object
It does not use Imageline, Imagefilledrectangle, and other graphical functions, and the library should provide objects such as line, Rectangle, and Oval, which can be used to make images. It should also support the ability to build larger (or more complex) objects or to group objects.
Z-values can be sorted
The charting program allows the painter to move the graphic object up and down on the surface of the screen. This library should be able to support the ability to put an object before and after other objects: it uses a Z-value to define the height at which the object starts from the cartographic plane. The larger the Z-value (The) the later the object is drawn (it will be) above the object with the smaller Z-values.
The above describes a clever way to create graphics using PHP 50, including aspects of the content, you want to be interested in PHP tutorial friends helpful.
