# imagepsbbox

(PHP 3 >= 3.0.9, PHP 4, PHP 5)

imagepsbbox -- Give the bounding box of a text rectangle using PostScript Type1 fonts

## Descrição

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.

## Parâmetros

`text`

`font`

  Pode ser 1, 2, 3, 4, 5 para as fontes embutidas (aonde números maiores correspondem a fontes mais largas) ou qualquer um dos seus própios identificadores de fonte registrado com 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.

`angle`

  `angle` is in degrees.

## Valores de retornado

Returns an array containing the following elements:

0 | left x-coordinate
1 | upper y-coordinate
2 | right x-coordinate
3 | lower y-coordinate

## Notas
