QUESTION
I want to fill my canvas with a image (base64-string) and than add a text into the canvas.
Initial idea (javascript browser application): I want to set the base64-string txtb64 (Image) as background image of the canvas and than add the text over it.
ANSWER
Answered 2019-May-03 at 12:14It looks like you should put the code needed to download the new image inside the "load" event handler of the image you create. This is needed because the load event could trigger after the code beneath it runs, resulting in an empty image being put onto the canvas.
Also you declare var image = new Image(); twice, which could also be causing issues. Calling one image1 and the other image2 will prevent that.
WARNING Running this snippet triggers a download request.
QUESTION
I'm currently working on a app-project, in which data (in form of variables) should be stored offline, while using this app.
I have successfully created an IndexedDB database in my app as you can see from the following browser screenshot:
I have created a signature pad where a user can draw their signature. I do not want to upload the signature image immediately to the server. Instead, I want to store the base64 string of the signature in IndexedDB. After storing it, I want to clear the signature pad and store the next signature image as a base64 string in IndexedDB, but avoid losing the string from the first signature.
I created the database with the following code. The variable imagetxtb64 is the base64 string of the signature.
