QUESTION
I'm working on a card maker app. The idea behind it is to have a CSV file with data for each card, a folder with images, and to create a card for each character I have once the CSV file is uploaded. So far so good, but I am stucked in writing the text in front of the canvas.
The canvas is created by overlapping a lot of different images, but the text appears on the very background and ends up being entirely covered by the other images. I want texts to be in front of it!
I trigger everything upon the loading of the CSV file containing the data, and I actually use a "context.fillText" but is not working as I want it to work.
How can I put the text from the variables inside the last 3 "context.fillText" on front of the canvas? The final scope is to have a single canvas I can save as an image.
And this is my code
...ANSWER
Answered 2020-Mar-21 at 15:39I think you can use .append()
and create text inside .contenitoreCarte
or even you canvas
the usage is too simple, here the document: https://api.jquery.com/append/
If you give me an example of your CSV I can submit a better answer by completing your code

This is the code to convert html to image using canvas.. I have one question like, when i clicks on the preview button the image is getting populated but if again try to click on the preview button , the two preview image is appearing.
How can I remove the first preview?
...ANSWER
Answered 2017-Jul-31 at 11:07You probably want to remove any existing child divs from the #previewImage
div before creating a new preview, so just use $("#previewImage").empty();
before invoking html2canvas
, or right after saving the image to disk.
For example:

Answered 2017-Jul-26 at 14:12Check this Fiddle.
You are getting this problem because you are drawing that in context and not adding that to canvas object. So after drawing in context you get that context data using ctx.getImageData(0, 0, img.width, img.height);
After that create a canvas element and put that image datac.getContext('2d').putImageData(data, 0, 0);
then create an fabricjs image object from that canvas image data.
*Crossorigin problem is there so fiddle not working, you can check this in your local server

...ANSWER
Answered 2017-Mar-03 at 13:38I found your html a bit complicated so I changed it to fit with my style. I did not use html2canvas, I was doing some annoying stuff for some reason, so I used another library that does the same thing.
