then prompting the browser to download it. I handle the download button clicks, generating a PNG for the selected signature and used to reflect the current information. I apply the current URL search parameters to the form values, allowing the URL to be Params.append( spacingInput.attr( "name" ), spacingInput.val() ) Params.append( slantInput.attr( "name" ), slantInput.val() ) Params.append( nameInput.attr( "name" ), nameInput.val() ) Apply the form to the URL (so that a refresh will re-render the same settings). I apply the current form values to the document rendering and URL query-string. the body somehow clears the fragment contents. CAUTION: We have to append the fragment to the body as the LAST STEP here Var fragment = u( template.first().content.cloneNode( true ) ) appropriate font-family and font-size. For each of the font options, I clone the template and add it to the document with the I add each of the font options as a LINK tag to the document head. SpacingInput.on( "change", applyFormValues ) ĭownloadButtons.on( "click", handleDownloadClick ) SlantInput.on( "change", applyFormValues ) NameInput.on( "input", applyFormValues ) Var downloadButtons = body.find( ".version_download" ) Var nameLabels = body.find( ".version_signature" ) queries will be executing in an expected state. First, let's get the dynamic parts into the document. CAUTION: Assumes that the "index-fonts.js" file was already loaded and exposed a But, I'm using CSS custom properties to apply the slant and spacing aspects across the entire document. The font-family property is hard-coded per clone. All I'm doing is wiring-up the button clicks. Really, all of the heavy lifting is being performed by the html2canvas API, which is incredibly simple to use.

That said, the JavaScript for this entire page is shockingly simple. Though, if you look at the HTML, you'll see that I also include an index-umbrella.js file to create some jQuery function parity. I recently switched from jQuery to Umbrella.js as my DOM helper because it just makes life so much easier in a few KB.

The element is then cloned once for each font family and append to the element:Īll of the DOM (Document Model Manipulation) is performed using Umbrella.js. The spacing of the signature (ie, CSS letter-spacing).The slant of the signature (ie, CSS transform: skew()).Here's the HTML page for signature generation. To that end, each one of these options is used to take a element and "stamp out" a cloned node. But, I decided to keep it simple and just use vanilla JavaScript. At first, I thought about using something like Angular or Vue. As such, in order to render them at roughly the same size on the screen, I increase or decrease the font-size property by the given number of pixels.Įach of these font options then becomes an example signature in my signature generation app. The visual size of each font family is wildly different. Notice that each option has an adjustSize property. I compiled a JavaScript file that contained an array of options: Which meant, the only thing left to do was wire it all together!įirst, I spent some time combing through the Google Fonts library, looking for font families that would make for decent-enough signatures.

And, a little trial and error proved that the html2canvas library was capable of rendering Google Fonts onto a canvas. In the past, I've used this library to generate meme images in Angular.Īs for the signatures, Google Fonts has a load of "hand written" fonts that kind of look like human signatures. This canvas element can then be flattened into a PNG and subsequently saved using the anchor download attribute. This library takes a "screenshot" of your HTML page (or an element within your page) by redrawing the DOM (Document Object Model) state onto an HTML Canvas element.
