I'm trying to build an application on KonvaJS with the Vue library. I've got a group layer where I'm drawing a circle inside the group. I am using the clip function to draw the circle.
While resizing the group, my circle strokes are uneven or get removed. I've made a sandbox for my code. You can find it here: https://codesandbox.io/s/elated-williams-51trtu
Please advise on how to resize the entire group without disturbing the strokes or circle.
Thanks.

I'm trying to create a mask out of a custom shape. I tried it with image masking and the result is given below. While my desire result is not exactly.
Using this Mask Image
The visual effect that I want to have:
Can anyone provide some hints on how can I achieve my desire effect.
What you have achieved via masking is working correctly. Masking works on alpha channel, transparent area vs visible area and images you posted in your question show exactly that.
Masking won't be enough for the effect you want to achieve. You need to experiment with CIFilter api.
Check out cifilter.io that shows a few examples of how these are supposed to look like. You might want to check out the source code for the same.
If you run this iOS project in Xcode, it provides a very easy way to browse and choose which effect is the closest to what you want to achieve.
Good luck!

In the Image above (Top Image), suppose the black boundary is the phone.
What i was trying to achieve is to randomly generate the red path from the top of the screen and at the same time the red line (path) moves downwards.
Notice how the red path is random and does not have a uniform shape.
My question is how do i achieve this?
I know this has something to do with the random function.
But then generating the random path has been my main obstacle since 8 hours.
I could not generate a shape at every interval of the timer with a specific x coordinate and y coordinate but then as you can see in the next image, how would i generate the line at an angle (rotated)
Have tried hard to search everywhere on the internet but failed.
I always keep stackoverflow my last destination after I fail to achieve any functionality after numerous hours.
Would really appreciate if anyone could help me out with this.
It looks like you could achieve the effect you wish by starting at the top center, and repeatedly choosing 2 random numbers: how far down to go, and how far horizontally to go (positive or negative), until you got to the bottom of the screen. You'd have to be careful not to go off either edge, or you could instead choose a random x-coordinate each step.

My problem is visible in this screenshot:
The letter "M" and a ship is cut in half. When I changing the camera position I can see that it looks like invisible boundary "eating" my nodes.
Any ideas what could be done wrong?
Does increasing the value of the zFar property of your camera help ?

I have an iphone app with a picture of a face in the uiimage. I want to only change the eye color on the face by tapping on a button or tapping on a color wheel. Can you give me some help in what code I would need.
I would suggest taking a look at OpenCV. It works quite well on iOS devices, the main code comes with examples on how to build iOS applications and there is a lot of material on how to do eye detection and from there you should be able to change the colors.
Keep in mind this is not a simple task and you could accomplish with a easier thing. But you could learn a lot and there are tons of good resources around this topics.
If you want to do something faster, you might be able to just detect the touch on the UIView(enable user interaction) and present a color picker, after the color has been presented you could create a simple view on top of the image that has a circle with the color that was selected. It would be crappy, but might be a good idea to do a simple simple prototype.
