Image Font can render images with text, using graphics as fonts. It takes a text string and creates an image on which the characters of the string are displayed using separate image files to render each character. The text may be aligned to the left, right, or center, or be justified. The image width may be limited so the text is wrapped if it exceeds the width limit. The character graphics may be mapped to image files with the same base name in a given directory. Alternatively, an array may be passed to define the paths of the character image files. The generated image may be saved to a file or displayed as the current script output in any of the formats supported by the PHP GD image extension.
svg-math-graphics is a class that can render a math formula as a SVG vectorial chart. It takes a string with a math formula and creates a chart on which it draws a set of lines between consecutive points for the axes. The class returns the chart data in SVG format. The size of the chart and the size of the steps between each point in the chart are configurable parameters. You can draw functions in Cartesian or polar coordinates.
