| reducePolygonSize( array $points, $size ) X-Ref |
| Reduces the size of a polygon The method takes a polygon defined by a list of points and reduces its size by moving all lines to the middle by the given $size value. The detection of the inner side of the polygon depends on the angle at each edge point. This method will always work for 3 edged polygones, because the smaller angle will always be on the inner side. For polygons with more then 3 edges this method may fail. For ezcGraph this is a valid simplification, because we do not have any polygones which have an inner angle >= 180 degrees. param: array(ezcGraphCoordinate) $points param: float $size return: array( ezcGraphCoordinate ) |
| reduceEllipseSize( ezcGraphCoordinate $center, $width, $height, $startAngle, $endAngle, $size ) X-Ref |
| Reduce the size of an ellipse The method returns a the edgepoints and angles for an ellipse where all borders are moved to the inner side of the ellipse by the give $size value. The method returns an array ( 'center' => (ezcGraphCoordinate) New center point, 'start' => (ezcGraphCoordinate) New outer start point, 'end' => (ezcGraphCoordinate) New outer end point, ) param: ezcGraphCoordinate $center param: float $width param: float $height param: float $startAngle param: float $endAngle param: float $size return: array |
| testFitStringInTextBox( $string, ezcGraphCoordinate $position, $width, $height, $size ) X-Ref |
| Test if string fits in a box with given font size This method splits the text up into tokens and tries to wrap the text in an optimal way to fit in the Box defined by width and height. If the text fits into the box an array with lines is returned, which can be used to render the text later: array( // Lines array( 'word', 'word', .. ), ) Otherwise the function will return false. param: string $string Text param: ezcGraphCoordinate $position Topleft position of the text box param: float $width Width of textbox param: float $height Height of textbox param: int $size Fontsize return: mixed Array with lines or false on failure |
| tryFitShortenedString( $string, ezcGraphCoordinate $position, $width, $height, $size ) X-Ref |
| If it is allow to shortened the string, this method tries to extract as many chars as possible to display a decent amount of characters. If no complete token (word) does fit, the largest possible amount of chars from the first word are taken. If the amount of chars is bigger then strlen( shortenedStringPostFix ) * 2 the last chars are replace by the postfix. If one complete word fits the box as many words are taken as possible including a appended shortenedStringPostFix. param: mixed $string param: ezcGraphCoordinate $position param: mixed $width param: mixed $height param: mixed $size return: void |
| renderToOutput() X-Ref |
| Render image directly to output The method renders the image directly to the standard output. You normally do not want to use this function, because it makes it harder to proper cache the generated graphs. return: void |
