Description
I have some SVG files using the fill attribute as for example
fill="rgba(255,0,0,0.2)"
and it renders back. Here for testing
<svg xmlns="http://www.w3.org/2000/svg" width="48" height="48" viewBox="0 0 48 48"><path d="M8 16h8V8H8v8zm12 24h8v-8h-8v8zM8 40h8v-8H8v8zm0-12h8v-8H8v8zm12 0h8v-8h-8v8zM32 8v8h8V8h-8zm-12 8h8V8h-8v8zm12 12h8v-8h-8v8zm0 12h8v-8h-8v8z" fill="rgba(255,0,0,0.2)"/></svg>
After some testing I found out that QSvgRenderer supports the fill-opacity
<svg xmlns="http://www.w3.org/2000/svg" width="48" height="48" viewBox="0 0 48 48"><path d="M8 16h8V8H8v8zm12 24h8v-8h-8v8zM8 40h8v-8H8v8zm0-12h8v-8H8v8zm12 0h8v-8h-8v8zM32 8v8h8V8h-8zm-12 8h8V8h-8v8zm12 12h8v-8h-8v8zm0 12h8v-8h-8v8z" fill="rgb(255,0,0)" fill-opacity="0.2"/></svg>
It would be better to support fill="rgba..." to rather than writing scripts to separated fill and fill-opacity fields on existing files.
Here's the code I use to render my icons
QFile file(iconPath); file.open(QIODevice::ReadOnly); baData = file.readAll(); // load svg contents to xml document and edit contents QDomDocument doc; doc.setContent(baData); file.close(); // Change the fill color attributes here // create svg renderer with edited contents const QByteArray docArr = doc.toByteArray(); QSvgRenderer svgRenderer(docArr); // create pixmap target (could be a QImage) QPixmap pix(svgRenderer.defaultSize()); pix.fill(Qt::transparent); // create painter to act over pixmap QPainter pixPainter(&pix); // use renderer to render over painter which paints on pixmap svgRenderer.render(&pixPainter); QIcon myicon(pix);
