Clash Royale CLAN TAG #URR8PPP Mapped color transformation on cors tainted image I need to transform colors in an image obtained from an s3 server which disallows crossOrigin. This is the functionality I need: const img = new Image(); img.src = src; ctx.drawImage(img, 0, 0); const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height); const colors = [25,50,100,255]; const data = imageData.data; for (let i = 0; i < data.length; i += 4) { if(data[i] == 1){data[i] = colors[1]} if(data[i] == 2){data[i] = colors[2]} if(data[i] == 3){data[i] = colors[3]} } but got tainted by crossOrigin error: I know I can not use getImageData in this case.

I did look into most of the information I found, and think I did understand the process, cause I was able to configure my s3 to allow cross domain access.. my express configuration: this.express = new Express(); this.express.all("*", (req, res, next) => { res.setHeader('Access-Control-Allow-Origin', "*"); res.setHeader('Access-Control-Allow-Methods', "POST"); res.setHeader('Access-Control-Allow-Headers', "content-type"); next(); }).options((req, res, next) => { res.end(); }); *I add a router down the modules folder hierarchy.. When I check the network tab this is what I see: I think that I have answered the CORS challenge, in the pre-flight OPTIONS request, but the second request is not called... WHY? ...
