The included in-memory image formats all use 16 bits per channel, even when handling images with lower bit depths like 8. This increases generality and decreases special cases at the cost of using more memory.There is no support for streaming chunks or pixels; most operations are one-shot. ...

The approach I used to solve the problem is:1-Calculate the memory required by the image2-Set the new memory_limit value 3-Create the PNG image and thumbnail4-Restore the original value1-The following value works for me:$required_memory = Round($width * $height * $size['bits']);Note...
