SVG to PNG with JavaScript
The code you provided is an HTML and JavaScript snippet that demonstrates how to convert an SVG file to a PNG image using JavaScript and an HTML canvas element. The code extracts the SVG content from the HTML, creates a new image element, draws the SVG on a canvas, converts the canvas to a data URL representing a PNG image, and then displays the PNG image on the page. The purpose of this code is to convert an SVG file, which contains text elements with Google Fonts, into a PNG image while preserving the font styles. The SVG file includes CSS styles to import Google Fonts and apply them to the text elements. One challenge encountered was that many SVG to PNG conversion options did not correctly translate the font from the CSS `@import` statement. To overcome this, the code uses JavaScript to directly render the SVG on a canvas and convert it to a PNG image. The workflow mentioned involves designing the thumbnail in Figma, exporting it as an SVG file, replacing the SVG fonts exported by Figma with `<text>` blocks and CSS classes to set the font family, and then rendering content into the text blocks using ERB (Embedded Ruby). To ensure that the SVG file correctly loads the fonts when converted to a PNG, the code base64 encodes the font files and embeds the full content of the font into the CSS styles for the text blocks. This ensures that the fonts are preserved when rendering the SVG on the canvas. Overall, the code provides a solution for converting an SVG file with Google Fonts to a PNG image while maintaining the font styles.
