imagepsbboxGive the bounding box of a text rectangle using PostScript Type1 fonts

Opis

array imagepsbbox ( string $text , int $font , int $size )
array imagepsbbox ( string $text , int $font , int $size , int $space , int $tightness , float $angle )

Gives the bounding box of a text rectangle using PostScript Type1 fonts.

The bounding box is calculated using information available from character metrics, and unfortunately tends to differ slightly from the results achieved by actually rasterizing the text. If the angle is 0 degrees, you can expect the text to need 1 pixel more to every direction.

Parametry

text

The text to be written.

czcionka

Może przyjąć 1, 2, 3, 4, 5 dla wbudowanych czcionek w kodowaniu latin2 (gdzie większy numer odpowiada większej czcionce) lub własny dowolny identyfikator czcionki zarejestrowany przez imageloadfont().

size

size is expressed in pixels.

space

Allows you to change the default value of a space in a font. This amount is added to the normal value and can also be negative. Expressed in character space units, where 1 unit is 1/1000th of an em-square.

tightness

tightness allows you to control the amount of white space between characters. This amount is added to the normal character width and can also be negative. Expressed in character space units, where 1 unit is 1/1000th of an em-square.
