Scale of image

[Iskander1220]

Hi, AdeelK93, and sorry for my english!

Do I understand correctly that on this link (https://github.com/AdeelK93/wapo_pdf/blob/823139583d49f48f7dadc650cd50266eba1a1f69/scales.R) is the calculation of the scale image value? Could you explain how this calculation is?

[AdeelK93]

This thing is super obfuscated. In the pressreader javascript, there is this function, from where I take that calculation:

calculateMagnifierScale: function(e) {
                        var t = l.magnifierPageSizes()[e];
                        return t ? Math.floor(Math.min(100 * t.W / this.width(), 100 * t.H / this.height())) : 0
                    },

That l.magnifierPageSizes comes from an endpoint at this address that only ever returns the widths and heights 1728 and 3024.
Rather than scraping that endpoint every time, I instead hardcoded those values and this calculation. Does that help?

Do I understand correctly - on the link GetIssueInfoByCid we getting the highest values W and H? And then what principle do calculations occur?

[AdeelK93]

Yeah that's the highest resolution available. What do you mean about what principle?

[Iskander1220]

There was meant which computation there are produced. Is it possible to determine which values ​​are taken from link, and how are they multiplied?
