These all seem to do the same thing. What are the pros/cons of each.
imagecopyresized() vs imagecopyresampled() vs imagecopy().
I'm resizing a user submitted image.
So I have an image shell created with '$newImage=imagecreatetruecolor(250, 250)'.
And now I want to copy the orginal image into the '$newImage'
imagecopyresized will copy and scale and image. This uses a fairly primitive algorithm that tends to yield more pixelated results.
imagecopyresampled will copy and scale and image, it uses a smoothing and pixel interpolating algorithm that will generally yield much better results than imagecopyresized at the cost of a little cpu usage.
imagecopy will copy but will not scale the image.
