L'�tiquette de <path>
|
Vous pouvez employer le <path> pour d�finir un chemin.
Copy le code suivant dans le bloc-notes et �conomiser le dossier en tant que ��path.svg��. Placer le dossier dans votre annuaire de Web seulement :
|
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100%" height="100%" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<path d="M250 150 L150 350 L350 350 Z" />
</svg>
|
|
L'exemple ci-dessus d�finissent un chemin qui commence la position 250 150 avec une ligne pour placer 150 350 puis l� d'une ligne � 350 350 et finalement de la fermeture le chemin de nouveau � 250 150.

L'exemple suivant cr�e une spirale :.

�l�ments de l'�tiquette de <path> :
|
L'�l�ment de chemin est l'�tiquette la plus utile simple pour cr�er le professionnel regardant le document de SVG et c'est le main-code d'�tiquette le plus difficile dans SVG.
Il est difficile de visualiser n'importe quoi mais le plus simple des chemins.
|
La table suivante d�crivent les attributs de l'�l�ment de chemin :
|
Attribute |
Explanation |
d |
A set of commands which define the path. (See below) |
pathLength |
If present then the path will be scaled so that the computed path length of the points equals this value. A negative value is an error. (Note: Unsupported by Adobe's plugin) |
transform |
A list of transformations. <Jump to: Transformation> |
Presentation Attributes |
Color,FillStroke, Graphics, Markers |
marker-offset |
auto length |
|
�l�ments des donn�es de chemin :
|
- Le chemin est d�fini dans l'attribut de ��d�� de l'�tiquette de ��chemin�� par une corde de l'espace blanc seperated des coordonn�es et des commandes.
La commande de chemin est cas-sensible, l'absolu d'utilisation des points d'une commande majuscule postioning et les points d'une commande de lettre minuscule sont relativement au dernier point.
L'une exception � ceci est le premier point emploie toujours postioning absolu.
|
Command |
Parameters |
Repeat |
Explanation |
M |
x,y |
Yes |
moveto: Moves the pen to a new location. No line is drawn. All path data must begin with a 'moveto' command. |
L |
x,y |
Yes |
lineto: Draws a line from the current point to the point (x,y). |
H |
x |
Yes |
horizontal lineto: Draws a horizontal line from the current point to x. |
V |
y |
Yes |
vertical lineto: Draws a vertical line from the current point to y. |
C |
x1 y1 x2 y2 x y |
Yes |
curveto: Draw a cubic bezier curve to the point (x,y) where the points (x1,y1) and (x2,y2) are the start and end control points, respectively. |
S |
x2 y2 x y |
Yes |
shorthand/smooth curveto: Draw a curve to the point (x,y) where the point (x2,y2) is the end control point and the start control point is the reflection of the last point's end control point. |
Q |
x1 y1 x y |
Yes |
Quadratic Bezier curveto: Draw a quadratic bezier between the last point and point (x,y) using the point (x1,y1) as the control point. |
T |
x y |
Yes |
Shorthand/smooth quadratic Bezier curveto: Draw a quadratic bezier between the last point and point (x,y) using the reflection of the last control point as the control point |
A |
** |
Yes |
elliptical arc: Draws and arc from the current point to x, y. The actual scale factor and position of the arc needed to bridge the two points is computed by the SVG viewer. |
z |
- |
No |
closepath: Closes the path. A line is drawn from the last point to the first. |
