Image Export

While the ChemDoodle Web Components are themselves a type of image for websites, you can export images using the API for storage or other media.

Image Types

The ChemDoodle Web Components image packages are contained in the ChemDoodle.io package. The following image types are supported:

  1. Portable Network Graphics (.png): Common bitmap graphics format allowing transparency.
  2. Web Scalable Vector Graphics (.svg): Web standard scalable vector graphic format.

Using the Image Packages

The image packages in the ChemDoodle Web Components implement 2 functions:

  1. string(): Generates a Javascript string defining the contents of the image as a text object.
  2. open(): Opens a new web page and includes the image in the DOM of this page.

Exporting PNG Images
Using the ChemDoodle.io.PNG package, you can export PNG images from ChemDoodle Web Components. The following examples show how this is done.





If you click on the Open Image in New Page button, you will see a PNG image (not a ChemDoodle Web Component). This is done by calling the ChemDoodle.io.png.open() function on the Canvas.

// create the canvas
var myCanvas = new ChemDoodle.ViewerCanvas('myCanvas', 100, 100);
// ... customize your canvas
// load a molecule or figure
myCanvas.loadMolecule(myMolecule);
// open the image in a new window
ChemDoodle.io.png.open(myCanvas);

You can also generate a string of the PNG by calling the ChemDoodle.io.png.string() function. Keep in mind that PNG is a bitmap format, so the string will be represented as Base64 text so you can use it in web pages, which will be text based.

ChemDoodle.io.png.string(myCanvas);

The string is output as the following:

Exporting SVG Images
SVG export works in the exact same way as exporting PNG images, except that you use the ChemDoodle.io.svg package instead. SVG is a scalable vector graphic, and can be increased in scale without loss of resolution, as the next comparison shows. You can zoom in on these images as compare the quality, the left image is the PNG and the right image is the SVG. SVG export can only be performed on 2D Canvases. Note that the ChemDoodle.io.svg package is included in proprietary builds only.

The string of the SVG looks like the following:
