    wordwrapimagewriter

    ES6 JS class to write text onto image with word wrapping

    Installation

    npm install wordwrapimagewriter --save

    Usage

    Write lines onto an image wrapping and automatically determining
    spacing and padding as specified

    // Instantiate the writer
    var writer = new wordwrapimagewriter({
      imgFilename: './imageToWriteOnto.png',
      availableLines: 3, // your maximum line number you allow
      topPadPx: 50, // spacing from top of image to move down before writing
      lineBottomPadPx: 5, // spacing at bottom of each line
      fontFile: './HelveticaBold.ttf',
    });
     
    // Call open to asynchronously load image before writing
    writer.openImg(() => {
      // The color declarations are from the node-gd package in rgba format
      var usernameColor = writer.img.colorAllocateAlpha(255, 20, 20, 1);
      var textColor = writer.img.colorAllocateAlpha(255, 255, 255, 1);
      var usernameText = "jenk37: ";
      var messageText = "I think that the wordwrapimagewriter is pretty good";
     
      // Write text onto the image. If the text takes more more lines
      // than availableLines, it will return the text that did not fit.
      var textThatWontFit = writer.writeText(usernameText, usernameColor);
     
      if (textThatWontFit) {
        console.log("[!] Text couldn't fit:", textThatWontFit);
      }
     
      // Change font or size. Changing size will automatically update lineLength
      writer.setFontSize(30);
      writer.setFont('./Helvetica.ttf');
     
      textThatWontFit = writer.writeText(messageText, textColor);
     
      if (textThatWontFit) {
        console.log("[!] Text couldn't fit:", textThatWontFit);
      }
     
      // Save the image file
      writer.save("./newImageFilename.png", () => {
        return callback();
      });
    });
