Use CTM transform
When working with SVG images, a powerful tool is the capacity to convert screen coordinates to SVG coordinates with accuracy and dependability. You can position elements on a website precisely where you want them with this conversion process, making page design much simpler.
Screen Coordinates To SVG Coordinates
An algorithm is used in this conversion process to turn a web page's coordinate values into an SVG file. This means that an SVG file will be created whenever a user clicks on an image or link on the page. The click will be recorded exactly where it was intended to be.
Understanding the distinction between a pixel and a point is essential to begin. In digital graphics, a pixel is a measurement unit, and 96 pixels make up an inch. Print graphics are measured in points, which are equal to 1/72 of an inch. Points must be used as the measurement unit when converting from screen coordinates to SVG coordinates.
It's time to look at how this conversion process works now that you know the fundamentals. This procedure's algorithm requires two inputs: the object's x- and y-coordinates on the web page. After that, it subtracts the result from the SVG coordinate system's origin point, which is in the upper left corner, and multiplies each coordinate by 72, which is the number of points per inch.
