Cloud Request - Unclear on response received
Thanks for your reply. What's the default canvas size (x and y co-ordinate ranges)? I'd like to see if I can scale it to values within this range - I do see you said don't recommend rescaling, but I would like to experiment a bit here.
Also, can you provide me other samples (x/y values) that I could look at for other text characters so that I can do a bit more experimentation
thx
Dear Pritvhi,
currently, it looks like the division to normalize the strokes impacted the precision of the float, and as the quality of the ink is not good (I know, it is our ink ;-) ), this results in a bad accuracy.
Normally, providing with ink "normally" written, it should be recognized, although we do not recommend to re-scale the ink.
Best regards,
Olivier
Apologies. I should have clarified. This is similar to your request - but with the 'hello' request x-y co-ordinate values that you had provided being translated into a scale between 0-1. However, the recognition doesnt return 'hello' as I had expected to
In order to verify - I plotted both the values you had provided, as well as my values (in the range 0-1) and they are identical. Note however, that I had to invert the y-values to a negative scale (y*-1) to make it plot the 'hello'. I am providing both plots FYI.
Dear Pritvhi,
you are not saying what is wrong in your request. Indeed, the following one is working fine on my side:

I did, but however it didn't work. Are the width and height values relevant? I have tried with your x-y co-ordinates translated into a range between 0-1. Is it possible for you to suggest what may be wrong?
Dear Prithvi,
currently, you should indeed tune the resolution accordingly, setting the xDPI and yDPI parameters: https://developer.myscript.com/docs/interactive-ink/1.2/web/rest/architecture/#overview-of-the-request
You can try with values such as 5 DPI based on the ink you send.
Best regards,
Olivier
I am enclosing the same x/y co-ordinates normalized to a range between 0 and 1. The plot in matlab is identical to the original. However, the curl command return 'w' instead of 'hello'

Is it possible that you attach a sample of your ink?
I will then check it carefully and update you.
Best regards,
Olivier
Hi, this ink is basically a plot of the strokes you provided in your request as a sample to try with curl. I wanted to see what the image represents. I have my samples that plot similarly and wanted to see if these are recognized (they don't :( )./
I'm a bit confused on the co-ordinate axes and what needs to be used - if I normalize your sample values in the [0,1] range these don't work - my ink samples belong in this range-
Can you point me on how the scaling needs to be setup to make this work? I did see some on the site, but don't think am too clear.. if you've any easy writeup on this, it'd help greatly.
Thanks
Prithvi
Dear Pritvhi,
Based on the X and Y coordinates, I am also getting the same image and result:
Where is this ink coming from? Indeed, we recommend having a good quality to ensure the best accuracy.
Best regards,
Olivier
Dear Pritvhi,
to answer your questions:
-Using the REST API, you can indeed remove the time information (you can either provide with an empty array, or even with not "t" parameter)
-The limit of a REST request is 700KB
Best regards,
Olivier
Thanks - just noticed this! :) - good observation
Is there a limit on the length of the x and y vectors, and can these be sent without the time parameter?
Dear Prithvi,
Can you please check again the return of your request? Using CURL, the result was displayed at the bottom line (hidden next to the login) :-)
Best regards,
Olivier
Ok, I did some manipulation (multiplying your 'y' coordinates with -1, and I do believe it looks like a 'hello' in a vague way. How do I attach a screenshot of this to make sure this may have been the original shape? Separately, can you also respond on the other question I had earlier.
"Thanks. Any reason it's getting truncated? I'm running from the command line of a MAC, and is there a way I can capture the entire output?"

Dear Prithvi Narayanan,
I am Olivier Rocher, from the technical support team at MyScript.
Please note in order to get a faster support, we recommend you submit any question you may have on our developer forum: https://developer-support.myscript.com/support/discussions.
To answer your question, it is not possible to use swagger-ui to test our endpoint because of the way we do authentication (via applicationKey and hmac).
You can test it for example using this curl command (please visit https://developer.myscript.com/support/account/registering-myscript-cloud/#computing-the-hmac-value to see how to produce your hmac value) :
curl -i -X POST \
-H "Content-Type:application/json" \
-H "Accept:application/json,text/plain" \
-H "applicationKey:your-application-key" \
-H "hmac:hmac-value" \
-d \
