php imagecopyresized vs imagecopyresampled vs imagecopy pros/cons
copy, gd, image, php
Solution
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.
Problem
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'
