Scaling png (?)

[AZJIO]

At work, I have electrical circuit diagrams for equipment. Can I create an application where I can select a schema and scale it? Nowadays, copying an archive of files is not convenient for everyone; everyone needs an application to press buttons.

yes there is ResizeImage()

but isnt this COMPLETE waste of energy and time ?
gallery image viewer can resize it with two fingers !?

This is not exactly what I want. I'm displaying HTML pages in a webgadget. Many people immediately want to enlarge it, but nothing happens, the text and pictures remain in their original size. One person who liked the idea of ​​a help file decided to look for these features himself and found some ideas:
https://stackoverflow.com/questions/436 ... s-and-html

I pasted this code and when you click on the picture, it increases by the specified size. I now have hope of upsizing. But this requires knowledge of JavaScript. It would be possible to make a TrackBarGadget over the image and I could set the magnification sizes. That is, if I need to make sprites to change with my fingers, then in HTML I can make a TrackBarGadget and change the scaling values. I would like all the JavaScript code to be embedded in the html, since I cannot access the file from the program interface to make changes to it. Therefore, the JavaScript code must be natively embedded in the html.

I've been trying to do what I want all day, but nothing has worked out.
I was given other ideas that could well replace my idea, that is, scaling the entire window and we tested it together, but in the end it did not work out guaranteed.

Code: Select all

<meta name="viewport" content="width=device-width, initial-scale=1.0">

and

Code: Select all

touch-action: auto

An image on an html page that is open in WebGadget. The files are located in the "Data" resource folder.
You can follow the links and download several files as an example. One of the archives (PB_User) contains the source code for the latest version.
