Solution to the problem of black edges appearing in screenshots shared by Empire cms

Empire CMS will only generate thumbnails with black borders on the left and right if the width is greater than the height (horizontal image). We open a picture with black borders and analyze it. Empire CMS scales images according to height. If the width is insufficient, it will be filled with black edges.

Solution: Change scaling based on height to scaling based on width, and then crop the higher part.

Modification method:

1. Open e/class/gd.php

2. Find the code

The code is as follows:

if($big_width >= $max_width and $big_height >= $max_height)
{
if($big_width > $big_height)
{
$tempx = $max_width / $ratioh;
$tempy = $big_height;
$srcX = ($big_width - $tempx) / 2;
$srcY = 0;
}

Modify to

The code is as follows:

if($big_width >= $max_width and $big_height >= $max_height)
{
if($big_width > $big_height)
{
$tempy = $max_height / $ratiow;
$tempx = $big_width;
$srcY = ($big_height - $tempy) / 2;
$srcX = 0;
}
