As I work on my Tumblr blog, I am experimenting with using jQuery to target photo entries (imgs) based on specific aspect ratios and resizing them accordingly.
To be more precise: If an image's width exceeds 250px, it should be resized so that the height is set to 250px with the width adjusted automatically. On the other hand, if an image's height is greater than 250px, it should be resized to have a width of 250px and the height set to "auto". Additionally, if the image is a perfect square, it should be transformed to a size of 250px by 250px.
Here is the current code snippet that I am utilizing. Please bear with me if it appears convoluted; I simply experimented until achieving some desired outcomes...
<script>
$(document).ready(function() {
$('.photo_post img').each(function() {
var maxWidth = 250; // Maximum allowed width for the image
var maxHeight = 250; // Maximum allowed height for the image
var ratio = 0; // Aspect ratio calculation
var width = $(this).width(); // Width of the current image
var height = $(this).height(); // Height of the current image
// Check if the current width exceeds the maximum limit
if(height > maxHeight){
ratio = maxWidth / width; // Calculate the scaling ratio
$(this).css("width", maxWidth); // Set the new width
$(this).css("height", height * ratio); // Adjust the height based on the ratio
height = height * ratio; // Update the height to match the scaled image
width = width * ratio; // Update the width to match the scaled image
}
// Check if the current height exceeds the maximum limit
if(height < maxHeight){
ratio = maxHeight / height; // Calculate the scaling ratio
$(this).css("height", maxHeight); // Set the new height
$(this).css("width", width * ratio); // Adjust the width based on the ratio
width = width * ratio; // Update the width to match the scaled image
height = height * ratio; // Update the height to match the scaled image
}
});
});
</script>
However, I am encountering issues whereby this script does not work correctly for all photos.
Given my limited familiarity with jQuery, I would greatly appreciate thorough and thoughtful responses.
