PHP and Image with GD library
I want to know the following aspects about GD library in PHP, so here my questions:
1/ I know we can write text in PHP on image using GD library. Can we rotate the text?
2/ Can we rotate an image or a text?
3/ Can we add shadow on the text?
4/ Can we move the text on any place on the image? I mean write the text anywhere on the image?
5/ On HTML5 Canvas, when you write a text,you cannot erase it as it is based on pixel. You have to clear the whole canvas and start again. I want to know if with GD library, can you clear a text if you have made a mistake and write another?
