Currently using the svgpath library to manipulate SVGs, I am looking for a way to alter the coordinate system so that the y-axis becomes the x-axis and the x-axis becomes the y-axis. Is there any method to achieve this? I have attempted to rotate around points (0, 0) and translate the figure by its height, but have not had success.
When used as an svg transform attribute, it appears as follows:
transform="matrix(0 1 1 0 0 0)"
<svg width="300" height="100" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<symbol id="pos" >
<path fill="none" stroke="black" d="M20,80 V20 H80 M20,20 80,80" />
<circle cx="20" cy="20" r="10" fill="red" />
<circle cx="80" cy="20" r="10" fill="yellow" />
<circle cx="20" cy="80" r="10" fill="green" />
<circle cx="80" cy="80" r="10" fill="blue" />
</symbol>
<!-- transposed -->
<use xlink:href="#pos" transform="matrix(0 1 1 0 0 0)" />
<!-- original, but moved to the side for comparison -->
<use xlink:href="#pos" transform="translate(150)" />
</svg>In the svgpath syntax, this transformation is represented as:
svgpath(__your_path__).matrix([0, 1, 1, 0, 0, 0])
In order to change the orientation or "handedness" of the desired operation, you will need to incorporate negative scaling. Typical rotations and scaling/skewing will maintain the orientation, but to achieve the desired change, consider applying a scale of -1 to the X axis and then rotating everything by 90° in a clockwise direction. While I have not personally tested this method, the following code snippet should theoretically work:
var transformed = svgpath(__your_path__)
.scale(-1.0, 1.0) //scale only X but not Y
.rotate(90)
.toString();
