Looking for a solution to crop an image for a carousel within a form? The croppa container is set at 300*167 px to fit the form. However, resizing the output image using the "quality" property leads to loss of image quality due to stretching. Is there a way to resize the container without affecting the output image?
In other words, is it possible to maintain the original proportional size of the image while only adjusting the croppa container to fit the form, similar to reducing it by scale?
For a creative solution, consider specifying the desired final size of the cropped item as 1150X640, which proportionally scales to 300*167. Here's an approach: Utilize the CSS property transform: scale(); to scale the child div in proportion to its parent.
var cropViewerWidth = 300;
var cropViewerHeight = 167;
// Ensure proportionate sizing according to the specified width and height
var cropWrapperWdith = 1150;
var cropWrapperHeight = 640
const scale = Math.min(
cropViewerWidth / cropWrapperWdith,
cropViewerHeight / cropWrapperHeight
);
const cropWrapper = document.getElementById('jsCropWrapper');
cropWrapper.setAttribute('style', 'transform: translate(-50%, -50%) scale(' + scale + ')');.crop-viewer {
width: 300px;
height: 167px;
overflow: hidden;
background-color: red;
}
.croppa-wrapper {
top: 50%;
left: 50%;
width: 1150px;
height: 640px;
background-color: blue;
/* If you are sure with scale factor then use mannuly here and don't use JS */
/* transform: translate(-50%, -50%) scale(0.26086); */
position: relative;
}
/* Additional styling */
.text-wrapper {
display: flex;
color: white;
font-size: 80px;
text-align: center;
height: 100%;
}
.text-wrapper > div {
margin: auto;
}<div id='jsCropViewer' class='crop-viewer'>
<div id='jsCropWrapper' class='croppa-wrapper'>
