I'm embedding VLC in my Tkinter app and I want to draw transparent images on it.
The problem is that Tkinter does not support transparency except for canvas.
If I add a canvas background image with create_image, I can't pass its winfo_id to set_xwindow() because the image is an int:
player.set_xwindow(image_on_canvas.winfo_id())
AttributeError: 'int' object has no attribute 'winfo_id'
I need to pass the image to add other transparent images over it.
If I create a frame or label to play VLC then I can't draw transparent images over it.

I just received the XD file from the designer, now am trying to extract the nav area image from the canvas but image is too spread out from the canvas how it can be cropped to the area of the nav.
Use Adobe Photoshop To Resize them to Fit Original image
or
if you want part of image you can use one of image magnify plugins first
they will fit image to canvas
then use export
Also you can use Web Export Plugins
I need to take a picture with a frame effect.
Can I preview camera image with the transparent PNG and later save the image?
Thanks!
Use nativescript-camera-plus plugin to add preview within your app, style it around with your frame.
Once the picture is taken, use nativescript-bitmap-factory to create a new image that combines your frame and the actual image form camera.
I was browsing the home page of canva.com
I was surprised by the UI effect of hover blur effect on the home screen. How can we develop such a feature on our website. Is it using CSS3 or some other javascript plugin libraries.
Thanks
They use a blurred background image, a canvas and an unblurred version of the image. Moving the mouse 'draws' (a portion of) the sharp image onto an otherwise transparent canvas. This makes it look like some kind of magic, when in reality it's just selectively copying a src image onto a canvas. I imagine a second, off-screen canvas is used to allow the 'drawn' lines to have their opacity faded. This canvas is then used to blend the copied image with the blurred image. Look into "canvas blending modes"
am using fabricjs library to crop images, i set freedrawing property to true to draw on images. how can i make this drawing transparent so the image still appear ?
Thanks
I'm trying to get the data from a canvas and set the src attribute of a img element. The problem here is that, the canvas has a background image setted with css, not with canvas methods. Is there any way or method to extract the background image so the toDataURL method could catch it?
Thanks
I guess there is a solid reason why you are not drawing the background image to the canvas itself so I can offer you this solution:
Draw the background-image to a second canvas element positioned below the first canvas.
When you want to take the canvas data and use it create a third canvas (no need to attach it to the DOM or make it visible.
Draw the background canvas onto it and then draw the main canvas on top.
Take the data from the third canvas.
Voila.
