KMScript.comDIGITIZED as KMScript
- Intro
- the engines provide the image/audio/keyboard/mouse/location/position etc.. for kmscript. for example:
- demo.Tester provide the OS desktop image
- Libjp.Camera provide the camera image
- the engine name start with LoweCase mean developer by kmscript, we can guarantee their safety.
- the name start with UpperCase are from our friend or third party.
- the engine always open at kmscript startup or engine changed
- fallback to null(none) if failed, for example: camera already removed
- same engine support the parameters, that can join like web url, for example:
width=1024&height=768&fps=10
- Example
- Image Engines
- none.Null, empty engine
- always succeed, provide 1x1(or size request) black image, all input got 0 and ouput ignored
- demo.Tester, for automated presentations
- the kmscript default engine, for local desktop, will get Desktop Image from Microsoft Windows/X11(Gnome/Xfce etc..)
- the deviceare ID/width/height for multiple displays
- melib.KMSI, the KMSIreplay
- to replay the KMSI must set the file path in the parameters, for example: pub/2021/0302.kmsi
- the replay always doing backguard, that mean after 5 seconds call search imagewill got the image of KMSI same time
(even KMSZ never use or jump or sleep or pause anything)
(and u may need padding for ready time in recorder step) - always last image when end of play
- melib.Image, the local image file
- parametersis file path, for example: pub/1.png or d:\my document\1.png
- can be files split by comma(for example: c:\a.png, pub/2.png, pub/p2021/22.jpg), access first file with pin number0, the pin 1 are next
- each get the image will check(reload as image if the file last modify time changed ) and return the image from file
- melib.Network, the network image
- parametersis url, for example: http://www.example.com/get?img=png
- the url will with x,y,width,height before request, for example request location 2,3 with size 10,20 the server got
GET /get?img=png&x=2&y=3&width=10&height=20
Host: www.example.com - the width or height may -1 if max by script call
- the server response must HTTP Code 200 and the Content-Type must start width image/, for example:
HTTP/1.1 200 OK
Content-Type: image/png - if the response headers with Last-Modified, the next request will have If-Modified-Since, so HTTP Code 304is supported
- parameterscan be kms protocol, for example: kms://192.168.1.11:8181/, get the image from another(192.168.1.11) kmscript, the requirement:
- can connect to target IP address that port, mean in same network or with router and firewall allowed
(ServerOnListenAddress must 0.0.0.0, this's default value of kmscript in libjp.json) - with same Sync Password(see W3Config)
- target kmscript already have an image engine
- target kmscript is not required to be a child node
- melib.Android_S0, Android Screen

- support melib.Network
- parametersis milliseconds of max wait, by default(if empty) is 2000
- after request, the engine wait the screen for any change(draw) until max time
- return the screen image before wait(changed)
- return the last image after wait(no change)
