What are the differences between a GD and a GD2 image?

Question

Reading the documentation for imagegd2(), and imagegd(), I noticed the functions are described, respectively as:

• Output GD2 image to browser or file
• Output GD image to browser or file

What are a GD2, and a GD image? What are the difference between those image types?

@JosefSábl, GD has been phased out more than 6 years ago; the question of backward compatibility is no longer relevant. – Swearword

Answer 2

Some version of GD generates only PNG, but recent version can ganerate GIF and PNG. Soon GD 1 will be no longer supported in next version of PHP.

"Soon GD will be no longer supported in next version of PHP." please add a reference/link to support this claim? – Swearword

Here it is : wiki.php.net/rfc/removal-of-deprecated-features Support for Freetype 1 and GD 1 - See R197385, R197386, R203752 and family commits – Gendarmerie

GD 1 will no longer be supported. That makes sense. GD2 support will stay. – Swearword
