In PDF.js, how do you hide the canvas and display the underlying text at full opacity?

由 半城伤御伤魂 提交于 2019-12-08 03:33:30
When PDF.js processes a PDF to HTML5, it lays a <canvas> over all the <div> elements containing the text. This canvas is a proper render of the PDF, while the text underneath is quite rough (but sufficient for certain purposes such as searching for words). Using the PDF.js demo page , I can make the underlying text visible by: Deleting the <canvas> element. Disabling the color: transparent property on the .textLayer class, which acts upon the underlying text. ... However, the text remains low-opacity, and I can't find the CSS that's controlling this effect (see below): Before - with canvas

PDF.js How do you print a multi-page pdf?

由 老子叫甜甜 提交于 2019-12-07 02:15:36
问题 I'm trying to add print functionality to a multi-page PDF embedded in a web page that is using the PDF.js library. It's problematic because I only have one page rendered at a time when a user is viewing it and the page is really rendered as an image in a canvas element. This question does not help in this case because it is for a single page PDF where printing the current contents of the canvas are acceptable. Same with this question. I also want to avoid just opening the PDF in another tab
