TreeMap can be sorted by keys, and LinkedHashMap maintains the insertion order.

Most likely, you need just to sort the output of the map contents in the desired order, which can be implemented like this using simple Comparator.comparing and Comparator.reverseOrder():

I manually replaced "ohm2013.pptx" with "ohm2013.odp" and "ohm2013.ods" and added it to my project.

I did this with the nodejs command prompt like this

npm install http-server -g

http-server "C:\Users\subUser\source\repos\Works\OdpViewerJs\ViewerJS"

Puppeteer: Get DOM element which isn't in the initial DOM

Asked 2020-Jul-22 at 06:50

I'm trying to figure out how to get the elements in e.g. a JS gallery that loads its images after they have been clicked on.

I'm using a demo of Viewer.js as an example. The element with the classes .viewer-move.viewer-transition isn't in the initial DOM. After clicking on an image the element is available but if I use $eval the string is empty. If I open the console in the Puppeteer browser and execute document.querySelector('.viewer-move.viewer-transition') I get the element but in the code the element isn't available.

...

ANSWER

Answered 2020-Jul-22 at 06:11

Since you have to wait until it is available, the most convenient method would be to use await page.waitForSelector(".viewer-move.viewer-transition") which would wait util the element is added to DOM, although this has the caveat that this continues execution the moment that the element is added to DOM, even if it is empty/hidden.

QUESTION

Calculation of a mouse position after multiple scales on different coordinates of image

Asked 2020-Jun-14 at 19:09

I am writing an image viewer JS component and i'm currently stuck on the calculation for the zooming in. I figured out the zooming in or out on one point (instead of just the center) using css transforms. I'm not using transform-origin because there will be multiple points of zooming in or out, and the position must reflect that. However, that's exactly where i'm stuck. The algorithm i'm using doesn't calculate the offset correctly after trying to zoom in (or out) when the mouse has actually moved from the initial position and I can't for the life of me figure out what's missing in the equation.

The goal is whenever the mouse is moved to another position, the whole image should scale with that position as the origin, meaning the image should scale but the point the mouse was over should remain in its place. For reference, look at this JS component. Load an image, zoom in somewhere, move your mouse to another position and zoom in again.

Here's a pen that demonstrates the issue in my code: https://codepen.io/Emberfire/pen/jOWrVKB

I'd really apreciate it if someone has a clue as to what i'm missing :)

Answered 2020-Jun-14 at 19:09

Thinking a little, I understood where the algorithm failed. Your calculation is focused on the information of offsetx and offsety of the image, the problem is that you were dealing with scale and with scale the data like offsetx and offsety are not updated, they saw constants. So I stopped using scale to enlarge the image using the "width" method. It was also necessary to create two variables 'accx' and 'accy' to receive the accumulated value of the translations

QUESTION

How can I prevent a PDF file from being downloaded or printed with PHP or JavaScript?

Asked 2020-May-27 at 19:43

I am looking for ways to present a PDF file in the browser but make it not downloadable or printable.

If someone really goes through all the trouble to disable the JavaScript library or anything like that, that is fine. This is more for the reason that the content within the PDF will be updated regularly so if you download it it will be out of date by the next day.

I also cannot rely on marking the pdf as protected or encryption as a reasonable way to accomplish this.

If you have any library recommendations or anything else it would be appreciated. I am currently exploring if it is feasible using PDF.js and ViewerJS

...

ANSWER

Answered 2020-May-27 at 19:43

I was able to find a solution using ViewerJS and this CSS. The CSS shows a blank page when you try to print (ViewerJS already distorts it to a non-printable state) and ViewerJS prevents you from downloading as a PDF file and instead tries to save as an HTML file.

This meets the requirements of making it just inconvenient enough to discourage users from trying to download the file since the file is always easily accessible on almost any page of the site.
