We have to pass some additional data. It's the canvas rendering context and viewport that will scale the page to the proper size if desired. Let's move on to a more useful example. We will describe the process of creating a simple PDF viewer with zooming and page changing, using the swipe gesture.
Our index. We have just one div container, canvas element and three javascript files at the end of the body tag to load them after all the content of the page had been loaded.
First, we will describe a function related directly to the displayed PDF files. We've created the openPage helper function that takes as a first argument a PDF file and the page number as a second. Most of the code should be familiar for you, but there are some thingd that need explanation. We've introduced the zoomed variable that got changed after double clicking the application screen zoom out.
Another double click zooms in the document. To calculate the scale factor, we divide the page div container element width by the viewport width. The last thing we do is setting the new page number and displaying the page using the openPage function.
Now, we will move on to the navigation part of the application. We will implement the double click and swipe events. We've created the lastTouchTime variable that stores time of the last touchstart event. If the difference between the current event time and the last one is lower than ms, then we run the toogleZoom function and of course reset the lastTouchTime variable value. The toggleZoom function just negates the value of the zoomed flag and uses the openPage method to display the current page.
Swipe gesture are a little bit more complicated. We have to handle two touch events. The touchmove and touchend. How to save rendered image in sketchup vray? How to save rendered image in sketchup?

Consequently, the text in the drawing can appear different than the text in the PDF file. You can prevent font substitution by capturing the font in the drawing and embedding it in the PDF file.
Alternatively, you can convert all text to geometry. Converting text to geometry ensures that the text in the PDF file is identical to that of the drawing. However, the PDF file size increases and text pixelation can occur when you view the PDF file at a high magnification. You can reduce pixelation by increasing raster image quality.
