PHP拇指调整png图像大小但添加黑色背景

Question

I am using PHPThumb to resize images rumtime. It is working fine but it add black background on PNG image. How could I resolve this? my path is

phpThumb/phpThumb.php?src={imagepath}&w=95&h=92

Answer 1

Here is the example to avoid black background:

src="/uploads/phpThumb.php?src=images/expressionengine_logo.png&w=100&f=png" 

src="/uploads/phpThumb.php?src=images/expressionengine_logo.png&w=100&bg=D4E9F7" 

Answer 2

Try replacing ImageCreateFromJPEG ($file) with ImageCreateFromPNG ($file)

Most probably this is the common error for the black background in the resized pngimage

Answer 3

Well, I am not familiar with PHPThumb but you can use SimpleImage library with this update.

I am using it and didnt faced any problems yet. This library has purposefully updated for the problem you are facing right now. Go to the links and try to use it.
