After spending a while looking through the forums, I haven’t been able to find a thread that deals with transforms on an image.
Essentially, what I’m trying to do is display and hide an image at the start of a level in a game I’m working on. The image should start out large and with 100% transparency, then shrink to a certain size within the camera bounds with no transparency, idle for a second, then fade back out the way it came.
How would this be done programmatically? Thanks in advance!
Please, I want to extract images from one site to another through the url using PHP. How can I be able to skip the small images like avatar on the site and select the bigger ones that I need?
I am using PHP file_get_contents.
I am using below css property inside a less file
background: url(‘../images/button-read-more.png’) no-repeat left top;
this is addded in custom module
app/code/Vendor/ModuleName/view/adminhtml/web/css/source/content-type/quote-item/_import.less
so wen image is being called it check at Magento/base module instead of Magento/backend
pub/static/version1591023269/adminhtml/Magento/base/default/vendor_modulename/images/button-read-more.png
I am unable to find a solution .
I have data in the table. But when I click the edit button, the data of the image has not been loaded yet
. This is my code

I have a grayscale image (given by a float matrix with values between (0, 1)) with a hole in it (a cluster of pixels/cells with values of -1).
Definitions:
The boundary of the hole as all the cells that are 4-connected to a hole pixel (a pixel with -1 value) (you can read more about pixel connectivity here: https://en.wikipedia.org/wiki/Pixel_connectivity).
I(v) is the color of the pixel v.
I need the fill the hole using this formula:
Denote the boundary with B. So for each u – hole pixel:
begin{equation}
I(u) = frac{Sigma_v{_in}_B w(u,v) * I(v))}{Sigma_v{_in}_B w(u,v)}
end{equation}
Where w is some arbitrary weighting function (for example using euclidean distance)
begin{equation}
w(v,u) = frac{1}{|| u – v||}
end{equation}
Denote the number of hole pixels with n, the naive solution will be O(n^2), since for each hole pixel, we sum over all boundary pixels (and the upper bound for the amount of boundary pixels is 4n, of course).
I was told a solution could be achieved in O(nlogn), but I couldn’t think of anything even close to that.
I thought of doing some bitwise operations, but I reached a dead end. I also tried reusing computations, but I couldn’t find any.
Moreover, the way I see it, there’s no avoiding calculating w(u,v) for the n^2 pairs of hole/boundary pixels – which is already more than O(nlogn).
What am I missing? Could you point me at the right direction?
Thanks

I’m trying to make the Mario move, but somehow it leaves traces behind, can anybody help???
var canvas = document.getElementById("screen");
var ctx = canvas.getContext("2d");
var mario;
var marioSprite;
var tiles;
var speedX = 1;
//marioSprite Specification
mario = {
//target picture specification X & Y, Width & Height
px:276,
py: 44,
pwidth: 16,
pheight: 16,
//drawing on Canvas specification X & Y, Width & Height
cx: 16,
cy: 116,
cwidth:16,
cheight:16,
}
//draw Mario in Canvas
function drawMarioSprite(){
marioSprite = new Image();
marioSprite.src = "https://gamedev.stackexchange.com/file:///C:/Users/MASTONO ALI/Desktop/img/characters.gif";
marioSprite.addEventListener('load', e => {
ctx.drawImage(marioSprite,
mario.px, mario.py, mario.pwidth, mario.pheight,
mario.cx, mario.cy, mario.cwidth, mario.cheight);
});
this.position = function() {
this.mario.cx += speedX;
}
position();
}//drawMarioSprite() end
//drawTiles and tilesLoop
function drawTiles() {
tiles = new Image();
tiles.src = 'file:///C:/Users/MASTONO ALI/Desktop/img/tiles.png';
tiles.addEventListener('load', e => {
tilesLoop();
});
}
function tilesLoop(){
for (let x = 0; x < 25; x++){
for (let y = 11; y < 13; y++){
ctx.drawImage(tiles,
0, 0, 26, 26,
x*12, y*12, 20, 20);
}
}
}//drawTiles() end
function draw(){
drawMarioSprite();

thank you
I tried the background image module, but it give me various issues.
Is there a really simple way to add a background image to all the website on the content region?
The theme is Bartik.
I was able to get the URL of the verctor_graphics reference media field with the following code:
file_url(node.field_vector_graphics(0).entity.field_media_image.entity.fileuri)
But how can I get the boolean media field value (machine name: is_animated)?
