EasySVG for PHP
Generate SVG images from SVG font easily.
The SVG data produced here is directly extracted from the font .svg file. This does not use the <text> tag.
Usage
require 'easySVG.php';
$svg = new EasySVG();
$svg->setFont("paris-bold-webfont.svg", 100, "#000000");
$svg->addText("Simple text display");
$svg->addAttribute("width", "800px");
$svg->addAttribute("height", "100px");
echo $svg->asXML();
This will output inline SVG for you to play with. You can echo it, save it to a file or whatever.
Method reference
setFont($path, $size, $color)
Sets the font attributes. This is a shortcut for :
$this->setFontSVG($path);
$this->setFontSize($size);
$this->setFontColor($color);
These 3 methods are explicit enough, I won't go through these in here.
addText($text, $x, $y, $attributes=array())
Add text to the SVG (will be converted to simple path)
- $text : String UTF-8 encoded
- $x : X position of the text (starting from left)
- $y : Y position of the text (starting from top)
- $attributes (optional) : list of tag attributes
asXML()
Return XML string of the whole SVG.
addAttribute($key, $value)
Add an attribute to the main SVG.
SVG data manipulation methods
You may need these to play around with SVG definitions.
defTranslate($def, $x=0, $y=0)
Applies a translate transformation to a definition. This basically applies matrix calculation to a definition.
defRotate($def, $angle, $x=0, $y=0)
Applies a translate transformation to definition. This basically applies matrix calculation to a definition.
defScale($def, $x=1, $y=1)
Applies a scale transformation to definition. This basically applies matrix calculation to a definition.
textDef($text)
Returns a SVG-formatted definition of a string. This method is used by addText method.
- $text : String UTF-8 encoded
textDimensions($text)
Returns the width and height of a string. This method is also used to set the width/height of the SVG (if none specified).
- $text : String UTF-8 encoded
unicodeDef($code)
Returns a SVG-formatted definition of an unicode character.
- $code : Unicode definition (in hex format)
characterWidth($char, $is_unicode=false)
Returns the width of a character.
- $char : Character
- $is_unicode : Boolean that tells if the character is a unicode string or a UTF-8 character.
addPath($def, $attributes=array())
Add a path to the SVG data
- $def : SVG definition
- $attributes (optional) : list of tag attributes
Utility methods
clearSVG()
Resets the SVG data. Used to start a new SVG without creating a new instance.
defApplyMatrix($def, $matrix)
Apply a matrix to a definition. Used to apply any kind of transformations, you shouldn't need this, but it is available so you may play with it.
