A Canvas control to support freehand drawing

This is a request for a new feature that I haven't seen across all of the Telerik products.

A new control that makes use of the HTML Canvas to allow for inking within web applications.

Can be used for free hand writing (inking) on mobile devices instead of requiring online keyboard in limited real estate scenarios. Can use to implement signature blocks on forms, convert to text, etc.

Hello Janick,

We have a separate feature request for an Image Editor that you can follow - this is the Blazor counter-part of the linked AJAX component.

Apart from the lack of image annotation, what else makes the Signature component unsuitable for your use case?

Dear Telerik Team

I am aware that this Request was closed quite some time ago, nevertheless I am not fully attracted by using the signature component for hand drawing in general.

In our use case, we don't want to use the canvas for signing or something the like. More so, we have a scenario where user's want to take hand notes (mostly on a blank background or maybe even on pictures) and save them.

This component you're offering ASP.Net Ajax seems fulfil the criteria:

https://demos.telerik.com/aspnet-ajax/imageeditor/examples/drawing/defaultcs.aspx

Is there something similar I missed or is there going be something the like in the near future?
Otherwise any help on this is appreciated.

Regards

I see this request has been out there for three years now. Signature capture is a common requirement and it would really be nice if Telerik would create a component for Blazor. I note that Syncfusion has one.

Hello Elie,

I updated the title to focus on drawing. I am leaving the page as it is for now, so the community can vote and comment on the idea. This will let us gauge the interest in such a component, and thus, prioritize accordingly.

Fair enough. However, since now I am focusing on Blazor, it would be great to have a Blazor component created with the professional quality of Telerik controls to capture signatures (hand drawing) and facilitate storage in database or a file system. Inking (hand writing recognition) functionality can be dropped.

Hi Elie,

The RadImageEditor control in our WebForms suite lets the end user draw on a canvas, so you could use that to capture a signature: https://demos.telerik.com/aspnet-ajax/imageeditor/examples/drawing/defaultcs.aspx. It does require a WebForms project, however. You can also download the source code of the component to see how we use the canvas and context and implement something similar on your own on top of a simple canvas element, without a component of ours at this point.

If by "inking" you mean recognizing handwriting to accept as user input instead of a keyboard - that's a massive feature that is well beyond the scope of UI components. At the very least, it requires some sort of AI to power it, and then it also has to be able to handle various languages. Even the current operating systems are not very advanced in this regard yet.

That said, I am leaving this idea public in the portal so we can see what the community thinks and gauge the interest in a similar signature/canvas/image editor component.
