How to use overflow hidden on 1fr grid element

Asked 2019-May-05 at 06:23

So I have this basic setup - a canvas area and an animator in a parent grid. The parent grid is also inside another grid with one 1fr row. I can resize the animator by dragging a resizer up and down.

I want the canvas to be bigger than its parent and hide its overflow, but that seems to also expand the parent element.

Normally you'd add a height to the grid container so that the the 1fr in the grid-template-rows: 1fr auto is meaningful; otherwise the grid item auto-adjusts to the dimensions of its contents.

Add overflow: hidden to the grid item #canvas-area along with a fixed height to the container (say 400px as your previous jsFiddle had) - see demo below:

QUESTION

HTML5 Canvas: Not drawing

Asked 2019-Apr-24 at 10:00

I'm currently creating a simple program using HTML Canvas and Javascript. All that I need to happen is for a ball to be drawn at coordinates on the canvas and then move around using some velocity variables etc.

The issue is, I've created a Ball object as I intend to have multiple balls on screen at a time, however nothing is showing on my canvas.

I've read over this a few times, I'm receiving no errors so I'm struggling to figure out what's happening with this.

EDIT: I've added a console log to check the drawSelf() is running, which it is but still no error/result

How to detect, that drawing a canvas object is finished?

Asked 2019-Apr-07 at 10:26

I have following JS code (found here, on stackoverflow, and a little-bit modded), which resize image on client side using canvas.

ANSWER

Answered 2019-Apr-07 at 10:26

Everything that should happen after the image has loaded, should be executed within the then callback, or called from within it.

It is important to realise that the code that is not within that callback will execute immediately, well before the drawing has completed.

QUESTION

Gradient fill SVG with jquery

Asked 2018-Jan-06 at 10:09

Is there a way to fill SVG with two or three gradient colors. Using following way I can fill a particular SVG path by one color. And radial gradient can be used but it cannot handle dynamic way. Colors need to define within SVG code. So I want to fill SVG path using two or three colors as a gradient as following way using jquery. And is there any possibility to do this using keith-svg plugin?

...

ANSWER

Answered 2018-Jan-06 at 10:09

As @Robert_Longson commented you can create dynamically the RadialGradient element and then apply it to the fill property:

This is a very basic way and need to be improved in order to consider colors and different properties as variable

ANSWER

A figimage is directly placed onto the canvas without axes. This means it does not automatically scale to the canvas or anything else and it also means that the zoom and pan tools do not have any effect.

You may use the resize argument to figimage, self.figure.figimage(img, resize=True) to let the canvas fit to the image, if that is what you want. Otherwise, you'd probably want to use an imshow plot.

In order to get the image scaled to its original size, you need to work a bit on the spacings.
