QUESTION

Using canvas, how to cut holes with inset shadows into an image?

Asked 2021-Jan-27 at 05:10

Using canvas, I'm trying to cut a series of round holes into an image. Additionally, each hole should have an inset drop shadow that would make it look as if the image is slightly hovering over the background.

Here is what I've managed to do:

Cut holes into an image using globalCompositeOperation = "destination-top"
Cut out one hole from a background shape using "opposite winding" (drawing counter-clockwise, then clockwise)

The second attempt, however, does not seem to be viable for multiple holes on an image for these two reasons:

AFAIK, can't draw an image counter-clockwise
AFAIK, for opposite drawing technique to work, I can't close the path in between calls to arc

Here is what I currently have:

You could put a div behind each hole and play around with the inset shadows in those to get a suitable effect (though the simple shadow in this snippet makes it look more like a button sticking out rather than a hole in I realize)

QUESTION

crop video element to fit a fabric js canvas

Asked 2020-Oct-15 at 10:56

I am trying to get a users camera to take a snapshot, then render the final to a square fabricjs canvas.

I use the browsers native webcam functionality, and as such it comes through at 640x480 on my laptop. the way I show this to the user is to display the video feed in a square view element 'camera-view' set to "object-fit: cover" to remove the letterboxing (it does then zoom in to match the height). The picture is then placed on a square canvas 'user-photo' that also is set to "object-fit: cover" to contains the rectangular image (hiding the sides and matching the video). The image also needs to display properly on a phone camera in portrait and this seems to work.

My issues arise when trying to copy this 'user-photo' to a fabric js canvas. I want it to only take a square copy of the canvas which it does. However, it always comes through just off center. I don't want to hard code any values as the canvas and video boxes may change in size, or the video at different resolutions. I'm pretty sure I've just got some calculations off when drawing the new canvas, or that the "object-fit: cover" constraint may be causing the behavior.

I have been looking and trying for the last two days on how to achieve this properly and have got close but it is still not working exactly as it should.

I've used parts from here: fabric.js - create Image object from ImageData object of canvas API , here Crop Functionality using FabricJs and others from around Stack Overflow.

Here is the main parts of the code and the full work in progress is here: JS Fiddle

Ok, so I managed to sort it out now.

My main cause of issue was that different cameras were providing different resolutions and aspect ratios that I wasn't properly using when drawing the canvases. I am now well versed in using the maximum amount of arguments in getContext("2d").drawImage(). Ha.

You can see a functioning 3 step versions here: JS Fiddle

The first step shows the rectangular webcam feed cropped to a square box. The second step takes the rectangular video feed, crates an image from it then draws it to a new canvas with calculated offsets to get a square 1:1 image. The third step redraws the canvas onto a fabricjs canvas as the background layer.

The second and third steps could probably be consolidated into a single one but for my purposes I wanted a regular canvas and then a fabricjs canvas.

Here is the javascript code as well:
