maska | Simple zero-dependency input mask for Vue.js and vanilla JS | Frontend Framework library

I would need advice on where in the program I did not release the allocated memory. In my opinion, it is somewhere in the commented part, which in this form was to compile me.

Here, in some way, I work with memory and try to free it.

When writing free(diagonaly); in if(nr<=0 ) throws me an error.

This condition is fulfilled at the moment when diagonaly diagonaly = (char**) malloc(sizeof(*diagonaly)*rDiagonaly) is allocated, but no line is allocated.

I have a program in which I try to read two lines of 40 characters. When something goes wrong or the program ends, I free array.

I'm getting an error message free(): invalid pointer Aborted (core dumped)

I think the problem is in the last cycle, but I can't solve it.

I'm not sure how to translate C++ std::unique_ptr::swap into Go.

I am using std::unique_ptr::swap in C++:

I have created an animated text, it works with SVG PATH and MASK.

The thing is that I do not understand why I can not fill it up in white :/

I tried to use fill attribut or stroke ... After all I did it has nothing to do. It's very weird, do you know why it does not take the color has expected ?

Someone has a solution or an idea on how to make it white ?

I am trying to generate 2 children from 2 parents by crossover. I want to fix a part from parent A and fill the blanks with elements from parent B.

I was able to mask both parents and get the elements on another array, but I am not able to fill in the gaps from the fixed part of Parent A with the fill elements from Parent B

Here's what I have tried so far:

I want to create a mask in css using png file but in a different way. Basically I don't want the mask to display the content underneath but I want it to CUT the content underneath and display everything else. So like negative mask. The important fact is that I want to mask the background image. Here is what I want to do::

I have 3 layers here. The first one is a video (html), then dotted background made as a repetitive background (CSS background) then a mask - needs to be png image as this will be the logo. I want the mask to remove the background underneath it and display the video.

I have I problem with multiplying two registers (or just register by float constant). One register is __m128i type and contains one channel of RGBA pixel color from 16 pixels (the array with 16 pixels is sending as a parameter to CPP dll). I want to multiply this register by constant to get grayscale value for this channel and do this operation also for other channels stored in __m128i registers.

I think that a good idea to use SIMD for convert image to grayscale is to use this algorithm.

fY(R, G, B) ＝ R x 0.29891 + G x 0.58661 + B x 0.11448

I have this following code and now it's only decomposing the image to channels and pack it together to return as an src vector. Now I need to make it for grayscale :)
The src variable is a pointer to unsigned char array.

I need to create a component that will let users choose from 2 choices in images. At first, you see 2 images side by side with a "handle" in the middle. If you move the handle to the left, you will see more of the image to right and less of the left image, as to reveal the right image, and vice versa.

Technically, I have 2 full size UIImageViews one on top of the other, and they are masked. I have a pan gesture and when the user slides the handle, the handle moves and the masks update themselves to adjust to "the new middle".

Here's the code responsible for adjusting the image mask. The constant is calculated in the method called by the gesture. I know my calculations of that constant are good because the "handle" and the masks are updated correctly.

BUT

the masks gets updated too late and when dragging, we see it being adjusted too late.
