Render method produces poor quality images.

[danvergara]

Description

Render method from render package only produces poor quality images. The images sees blurry and seems the images' size is fixed to 612 × 792 pixels.

Expected Behavior

Higher quality images out pdf pages.

Actual Behavior

I've been consuming the unipdf package as a library, but the easiest way to reproduce this is running the cli.

unipdf render -o images.zip in_file.pdf
I got the exact same result.

Attachments

I'm attaching the Bitcoin Whitepaper because that was the pdf file I was testing against and the first one that came to my mind that is free to download.

unipdf render -o bitcoin.zip bitcoin.pdf

@danvergara you could set the image width by doing it like this:

device := render.NewImageDevice()
device.OutputWidth = 2048

The height will be calculated accordingly. This is the image output example of it
