Sorry, I can’t attach a PDF due to confidential information. Also, this only happens to certain customers of my company. In other words, I can’t reproduce the bug because it’s too difficult to reproduce.
I found a method called setCanvasMultiplier in Core, so what do you think about solving the problem by using that method to increase the resolution when the zoom out button is pressed? Is this the best approach?
Perhaps this bug is caused by a loss of resolution due to the user’s environment. So it would be better if the resolution could be increased.
But there still seems to be some poor quality PDFs.
I found an article on the web that uses pdf.js with the following code to improve image quality, can something similar be done with pdf.js express? The website referenced and code are below.
I’ve displayed the PDFs I have on the demo site, but I’d like to improve the image quality. Are the PDFs displayed on the demo site rendered in the highest quality possible? If so, I can give up on the idea of not being able to increase the image quality any further with this library. I’ve also attached the PDFs I have.
