Increase zoom factor in Gala's Zoom plugin

[mmohsinkhan]

I am a software developer with eye sight problem, I need screen magnification to carry out routine work on my computer.

Screen magnification works on Elementary OS but current max magnification factor (2.5 times) is not enough for me. Please make it at least 6 times. If required I can open Pull Request with increased magnification factor.

For now I have build and installed gala from source after increasing magnification factor.

Best Regards

I saw your post on Reddit some time ago and actually wanted to create an issue here. Good that you were faster 😀️

How did you implement it? Did you just increase the maximum zoom factor to 6.0f?

gala/plugins/zoom/Main.vala

Lines 85 to 86 in 266bc58

	else if (current_zoom >= 2.5f && @in)
	return;

So you can now increase the zoom factor with a step size from 0.5f to 6.0f?

gala/plugins/zoom/Main.vala

Line 124 in 266bc58

current_zoom += (@in ? 0.5f : -0.5f);

Maybe it would be a good idea to make the maximum zoom factor and step size adjustable in Switchboard Display Plug?

Good to see you here, because of you I'm using EOS as my daily driver.

I made the simplest change possible to make it work on my system, changed 2.5f to 6.0f on line # 85 🥇

+1 for Switchboard Display Plug option.

Because of me? What have I done? 😅️

It was not possible for me to use EOS with out of the box magnification factor. Because of your answer on Reddit I was able to increase magnification factor.

I didn't answer your question at Reddit. Another user was faster 😁️

Ohh. Hehe.
But still I must say thanks, you are marking required updates in source code here.

I was using Deepin before I switched to EOS. Only reason I started exploring other distro was because desktop magnification stopped working properly on their Deepin latest build v20.
