Dynamic border radius experiment
This was just a little experiment to see if I could manipulate the border radius of shapes on the slide numerically using JavaScript, and the answer is yes. Not sure of any use case, but I've always wanted to be able to control the border radius numerically in Storyline as border radius is not maintained when resizing shapes. I'm not sure if this could help as there is no easy way of targeting specific shapes in a slide without knowing their unique ID. It was a bit of fun anyway. If anybody would like to play or expand on this, go for it. What I've found so far, is it will only support solid or no outlines on shapes. When you start using other styles (dot, dash) an image is used by Storyline to achieve this. window.updateCornerRadius = function(targets, radius) { targets.forEach(function(target){ const path = document.querySelector(`[data-dv_ref="ref-${target}"] path`); if (!path) { console.error(`SVG target ${target} not found.`); return; } // Extract the bounding box of the current path const bbox = path.getBBox(); const x = bbox.x; const y = bbox.y; const width = bbox.width; const height = bbox.height; // Ensure radius doesn't exceed half the width or height radius = Math.min(radius, width / 2, height / 2); // Construct a new path data string with the updated corner radius const newPathData = ` M ${x + radius},${y} H ${x + width - radius} A ${radius},${radius} 0 0 1 ${x + width},${y + radius} V ${y + height - radius} A ${radius},${radius} 0 0 1 ${x + width - radius},${y + height} H ${x + radius} A ${radius},${radius} 0 0 1 ${x},${y + height - radius} V ${y + radius} A ${radius},${radius} 0 0 1 ${x + radius},${y} Z `; // Update the path's "d" attribute path.setAttribute("d", newPathData); }); } An example of this being called. I'm using a variable, borderRadius, change trigger. const borderRadius = getVar("borderRadius"); window.updateCornerRadius(['12','15','18','21'], borderRadius);
