(PHP 4, PHP 5)
imagettfbbox вЂ” Give the bounding box of a text using TrueType fonts
This function calculates and returns the bounding box in pixels for a TrueType text.
The font size in pixels
Angle in degrees in which text will be measured
The name of the TrueType font file (can be a URL). Depending on which version of the GD library that PHP is using, it may attempt to search for files that do not begin with a leading '/' by appending '.ttf' to the filename and searching along a library-defined font path
The string to be measured
imagettfbbox() returns an array with 8 elements representing four points making the bounding box of the text:
|0||lower left corner, X position|
|1||lower left corner, Y position|
|2||lower right corner, X position|
|3||lower right corner, Y position|
|4||upper right corner, X position|
|5||upper right corner, Y position|
|6||upper left corner, X position|
|7||upper left corner, Y position|
The points are relative to the text regardless of the angle , so "upper left" means in the top left-hand corner seeing the text horizontally.
Note: This function requires both the GD library and the » FreeType library.
