How to get ROI function in ws-scrcpy?

[aitech95]

Scrcpy has a ROI function via inputting four parameters x,y, width and height.

How can I get this ROI function in the ws-scrcpy?

Could you help me?

Thanks!

Hi,, @aitech95. What is ROI?

[aitech95]

Hi, Thank you very much for your reply. ROI means "region of interest". Scrcpy can use command to input four parameters x,y, width, and height to output part of the android screen, where (x,y) are coordinates of the start point, width and height are to the width and height of ROI. It will be great if ws-scrcpy could also output the part of the screen by four parameters x, y, width and height. I'm looking forward to hearing from you!

There is the crop field in the VideoSettings class:

ws-scrcpy/src/app/VideoSettings.ts

Lines 18 to 20 in 344e35e

	export default class VideoSettings {
	public static readonly BASE_BUFFER_LENGTH: number = 35;
	public readonly crop?: Rect | null = null;

You can set it to the desired value to it to achieve same result as with the --crop option in the original scrcpy.
The is no way to set it in the UI, but it should be easy to implement.
