Imagecolorallocate allocation failed

Imagecolorallocate allocation failed

$ ImageHand = imagecreatefromgif ("images/mb.gif"); $ color = imagecolorallocate ($ imageHand, 0, 0); var_dump ($ color );

However, my imagecolorallocate always fails to be allocated. as a result, all the fonts in the future will be white and cannot be clearly viewed. what can I do to clear them?

What is the error?

Paste your image

You can use imagecreatetruecolor to create an image. if your image is 8bit, this is not acceptable.

That is, an error is not reported. I will manually run the var_dump command to return a false value for this color variable each time.

How can I check the picture? 8bit?

The problem is that you cannot assign colors.

Do you want to paste the image?
