imagecreatefrompng() Producing Black Background Instead of Transparent Area?

In PHP, the imagecreatefrompng() function is commonly used to work with PNG images. However, it has been observed that when using this function, PNG transparency may be converted into a solid black color.

To resolve this issue, the following steps can be implemented after creating a new canvas using imagecreatetruecolor():

1. Allocate a Black Color: Assign a black color to an integer variable using the imagecolorallocate() function.
2. Remove Black from Transparency: Utilize the imagecolortransparent() function to set black as the transparent color, effectively making it invisible.
3. Disable Alpha Blending: Use imagealphablending() with a false value to prevent the alpha channel from being blended into the image's colors.
4. Enable Alpha Channel Preservation: Employ imagesavealpha() with a true value to maintain the full transparency range.

By implementing these modifications, the alpha channel information in the PNG image will be preserved, preventing its conversion to a black background. The updated code would resemble the following:
