Wrong $fillColor Inside function resizeInsideRect()

[applibs]

This function has param $fillColor = null abn when is not passed, image is filled black color! Who said that background color must be black and not white or transparent. I expect transparent color and other colors only when is passed.

Something like this:

if ($fillColor) {
                if (is_numeric($fillColor)) {
                    $fillColor = $this->getColorRGB($fillColor);
                }
            } else {
                // $fillColor = $this->getColorRGB($this->getColorAt(0, 0));
            }
            
            $rect = WideImage::createTrueColorImage($width, $height);
            if($fillColor) {
                $rect->fill(0, 0, $rect->allocateColor($fillColor));
            } else {
                $rect->fill(0, 0, $rect->setTransparentColor(0));
            }

Currently, it falls back to the colour of pixel in corner, which sounds reasonable to me. Your image probably has fully-transparent black pixel. The issue is that it does not preserve the alpha.

Does the following change fix your issue?

diff --git a/lib/TrueColorImage.php b/lib/TrueColorImage.php

Yes, its correct now.
