Magnification Windows API - How to add Smoothing/Anti Aliasing

Asked 2021-Jun-15 at 20:44

Context

Since Windows 10 version 2004 update, the Magnifier windows application was updated. And as with every update, there are some issues with it.

Since those issues might take a long time to fix, I've decided to implement my own small project full screen magnifier.

I've been developing in c#, .Net 4.6 using the Magnification API from windows magnification.dll . All went good and well, and the main functionality is now implemented. One thing is missing though, a smoothing Mode for pixelated content... Windows Magnifier implements an anti aliasing/ smoothing to the Zoomed in content.

I've checked and the Magnification API, doesn't seem to provide that option.

how do i add smoothing mode to magnifier on windows magnification API?

I'm aware of pixel smoothing methods, but not familiar with win32 API to know where to hook the smoothing method to, before the screen refreshes.

EDIT:

Thanks to @IInspectable answer, after a small search i found this call to the Magnification API in a python project.

Based on that, I wrote this snippet in my C# application , and it works as intended!

There is no public interface in the Magnification API that allows clients to apply filtering (other than color transforms). This used to be possible, but the MagSetImageScalingCallback API was deprecated in Windows 7:

This function works only when Desktop Window Manager (DWM) is off.

Even if it is still available, it will no longer work as designed. From Desktop Window Manager is always on:

In Windows 8, Desktop Window Manager (DWM) is always ON and cannot be disabled by end users and apps.

With that, you're pretty much out of luck trying to replicate the results of the Magnifier application's upscaler using the Magnification API.

The Magnifier application appears to be using undocumented API calls to accomplish the upscaling effects. Running dumpbin /IMPORTS magnify.exe | findstr "Mag" lists some of the public APIs, as well as the following:

MagSetLensUseBitmapSmoothing
MagSetFullscreenUseBitmapSmoothing

Unless you are willing to reverse-engineer those API calls, you're going to have to spend your time on another project, or look into a different solution.

A note on the upscaling algorithm: If you look closely you'll notice that the upscaled image doesn't exhibit any of the artifacts associated with smoothing algorithms.

The image isn't blurred in any way. Instead, it shows sharp edges everywhere. I don't know what upscaling algorithm is at work here. Wikipedia's entry on Pixel-art scaling algorithms lists some that have very similar properties. It might well be one of those, or a modified version thereof.

QUESTION

Magnifier glass and image alignment

Asked 2021-May-22 at 09:51

I used the magnifier code from w3schools to create an HTML page. If I keep the image left aligned (i.e., on the left border), the magnifier works fine. If I center the image however (my preference), the magnifier doesn't track with the image (it stays on the left). Any idea how I can fix this problem? The code is pasted below. Thanks for any help- I'm a novice and this is driving me crazy. Steve

ANSWER

Answered 2021-May-22 at 09:49

The problem is that, though you have moved the image centrally (by dint of text-align) you have not compensated for that in the positioning of the glass.

At its simplest the image has moved window.innerWidth/2 - img.width/2 (not accounting for any possible padding or margins etc which may be there in a production page). The value of x for the glass is adjusted by this amount in this snippet.

JavaScript Code works in Firefox but not in Chrome or Edge

Asked 2020-Dec-04 at 08:40

I have made my own Audio Player with JavaScript using the p5.js library. The script loops through all elements of the webpage with onload() and adds a canvas (The thing that displays the graphics) object to all html elements of class audioPlayer. With Firefox it all works fine and it can play an audio file from a specified file path. When i load my website inside of Chrome or Edge, I get the following error message in the console:

ANSWER

Answered 2020-Dec-04 at 08:40

The security policy of Firefox is different from chrome and edge. It may be because you open the html file directly on local machine. This will cause Chrome and Edge to be unable to directly access local resources. If you want to run in chrome and edge, please create a web server to run this file.

Be similar to this question.

And you can make chrome have permission to access the file. link
