Dear XiangJue,

I recomment you play with the webDemo and look for the messages in the console: https://webdemo.myscript.com/views/text/index.html

Doing an erasure I had the following message:

{"type":"svgPatch","updates":[
{ "type": "REMOVE_CHILD", "parentId": "BACKGROUND-guides", "index": 0 },
{ "type": "REMOVE_CHILD", "parentId": "BACKGROUND-guides", "index": 0 },
{ "type": "REMOVE_CHILD", "parentId": "BACKGROUND-guides", "index": 0 },
{ "type": "REMOVE_CHILD", "parentId": "BACKGROUND-guides", "index": 0 },
{ "type": "REMOVE_CHILD", "parentId": "BACKGROUND-guides", "index": 0 },
{ "type": "REMOVE_CHILD", "parentId": "BACKGROUND-guides", "index": 0 },
{ "type": "SET_ATTRIBUTE", "name": "viewBox", "value": "0 0 1920 100 " },
{ "type": "SET_ATTRIBUTE", "name": "height", "value": "100px" }
],"layer":"BACKGROUND"}

Applying all the SVG patches should normally update properly your background.

Best regards,

Olivier

Dear XiangJue,

can you confirm you apply SVG Patch, which will allow you to remove the erased stroke: https://developer.myscript.com/docs/interactive-ink/1.3/web/websockets/messages/#pending-stroke-management

Let us know if this helps.

Best regards,

Dear XiangJue,

Currently, I am not sure to understand.

Is it possible to have the different types of requests your are sending to our server? This will help understand.

Thank you,

Best regards,

Olivier

Dear 新 雷,

Currently, how do you add your strokes? In batch mode (all strokes at once), or as soon as they are written? Indeed, in the latter case, gestures are normally set and detected when written. Otherwise, in batch mode these are indeed not activated.

Best regards,

Olivier

Dear 新 雷,

Thank you for your update.

In the configuration of your code sample, you should make following changes:

1. The configuration message must be sent before creating the part, else the configuration is not applied to the new part. So you must move your configuration block code before your contentpart block code.
2. In your configuration json there is a small mistake on the language key name: it must be "lang" (not "language"). So in your code the line "\"language\":\"zh_CN\",\n"+must be replaced by "\"lang\":\"zh_CN\",\n" +

With those updates, the strokes are recognized as 干as you expect.

Regards,

Gwenaëlle

Dear 新 雷,

Currently, I changed language using the samples available at the following location: https://myscript.github.io/myscript-text-web/#/elements/myscript-text-web/demos/other-examples

Under Chrome, using the inspector, I have the following message when switching to the cs_CZ language:
{
"type":"configuration",
"alwaysConnected":false,
"lang":"cs_CZ",
"text":{
"guides":{"enable":true},
"smartGuide":true,
"smartGuideFadeOut":{"enable":false,"duration":10000,"enabled":false},
"mimeTypes":["text/plain","application/vnd.myscript.jiix"],
"margin":{"top":20,"left":10,"right":10},
"configuration":{"customResources":[],"customLexicon":[],"addLKText":true}}
}

Comparing with your message, the only difference I see that you replaced "guides" with "guides":
{
"type":"configuration",
"lang":"zh_CN",
"text":{
"margin":{"top":0,"left":0,"right":0},
"guide":{"enable":true},
"configuration":{"addLKText":true}
}
}

Can you please check this?

Let us know if it helps.

Dear 新 雷,

thank you for the update.

Based on the above, your language configuration of the webSocket seems fines. It is indeed similar to the documentation: https://developer.myscript.com/docs/interactive-ink/1.3/web/websockets/messages/#configuration

Which ink are you sending? Can we have the X and Y coordinates.

Is it possible to have your code, so that we can investigate further?

Best regards,

Olivier

Dear Sir,

thank you for contacting us.

First, there is no reason webSocket cannot be done on Android.

On your side, can you confirm you get the "partChanged" event before sending the configuration and strokes?

Best regards,

Olivier
