Classe: Image_Canvas_Tool - X-Ref
This class contains a set of tool-functions.| fontMap($name, $type = '.ttf') X-Ref |
| Maps a font name to an actual font file (fx. a .ttf file) Used to translate names (i.e. 'Courier New' to 'cour.ttf' or '/Windows/Fonts/Cour.ttf') Font names are translated using the tab-separated file Image/Canvas/Tool/fontmap.txt. The translated font-name (or the original if no translation) exists is then returned if it is an existing file, otherwise the file is searched first in the path specified by IMAGE_CANVAS_SYSTEM_FONT_PATH defined in Image/Canvas.php, then in the Image/Canvas/Fonts folder. If a font is still not found and the name is not beginning with a '/' the search is left to the library, otherwise the font is deemed non-existing. param: string $name The name of the font param: string $type The needed file type of the font return: string The filename of the font |
| mid($p1, $p2) X-Ref |
| Return the average of 2 points param: double P1 1st point param: double P2 2nd point return: double The average of P1 and P2 |
| mirror($p1, $p2, $factor = 1) X-Ref |
| Mirrors P1 in P2 by a amount of Factor param: double $p1 1st point, point to mirror param: double $o2 2nd point, mirror point param: double $factor Mirror factor, 0 returns $p2, 1 returns a pure return: double $p1 mirrored in $p2 by Factor |
| controlPoint($p1, $p2, $factor, $smoothFactor = 0.75) X-Ref |
| Calculates a Bezier control point, this function must be called for BOTH X and Y coordinates (will it work for 3D coordinates!?) param: double $p1 1st point param: double $p2 Point to param: double $factor Mirror factor, 0 returns P2, 1 returns a pure return: double P1 mirrored in P2 by Factor |
| bezier($t, $p1, $p2, $p3, $p4) X-Ref |
| Calculates a Bezier point, this function must be called for BOTH X and Y coordinates (will it work for 3D coordinates!?) param: double $t A position between $p2 and $p3, value between 0 and 1 param: double $p1 Point to use for calculating control points param: double $p2 Point 1 to calculate bezier curve between param: double $p3 Point 2 to calculate bezier curve between param: double $p4 Point to use for calculating control points return: double The bezier value of the point t between $p2 and $p3 using |
| getAngle($x0, $y0, $x1, $y1) X-Ref |
| Gets the angle / slope of a line relative to horizontal (left -> right) param: double $x0 The starting x point param: double $y0 The starting y point param: double $x1 The ending x point param: double $y1 The ending y point param: double The angle in degrees of the line |
