PHP: imageloadfont

Description

int imageloadfont ( string file )

imageloadfont() loads a user-defined bitmap font and returns an identifier for the font (that is always greater than 5, so it will not conflict with the built-in fonts). It returns FALSE in case of error.

The font file format is currently binary and architecture dependent. This means you should generate the font files on the same type of CPU as the machine you are running PHP on.

Table 1. Font file format

byte position	C data type	description
byte 0-3	int	number of characters in the font
byte 4-7	int	value of first character in the font (often 32 for space)
byte 8-11	int	pixel width of each character
byte 12-15	int	pixel height of each character
byte 16-	char	array with character data, one byte per pixel in each character, for a total of (ncharswidthheight) bytes.

Example 1. Using imageloadfont

<?php $im = imagecreate(50, 20); $black = imagecolorallocate($im, 0, 0, 0); $white = imagecolorallocate($im, 255, 255, 255); imagefilledrectangle($im, 0, 0, 49, 19, $white); $font = imageloadfont("04b.gdf"); imagestring($im, $font, 0, 0, "Hello", $black); imagepng($im); ?>

Since there are few fontfiles avaible, I wrote a small windows-programm to generate them from the installed fonts.

Sometime ago I wrote a small tutorial on how to create dynamic signatures using gd_fonts. I also uploaded some gd_fonts...

You all should look at the GD image library site for information on extra fonts, it can be found at http://www.boutell.com/gd/
