It works with local and remote files.

You can specify the resize ratio. To make the image smaller it should be < 1 and to make it bigger > 1.

  1. $ir = new ImageResizer();
  2. $ir->setFormat(ImageResizer::FORMAT_PNG);
  3. $ir->setSource("./original.jpg");
  4. $ir->resize(0.5);
  5. $ir->setDestination("./avatar.png");
  6. $ir->writeOutput();

Or you can specify what width and height you want and it will calculate the needed ratio keeping the proportions.

  1. $resizer = new ImageResizer();
  2. $resizer->setFormat(ImageResizer::FORMAT_JPEG);
  3. $resizer->setSource("./original.jpg");
  4. $resizer->setWidth(120);
  5. $resizer->setHeight(90);
  6. $resizer->resize();
  7. $resizer->setDestination("./thumbnail.jpg");
  8. $resizer->writeOutput();

The code is totally free. You can use it and modify it as you wish.
There are some documentation and examples in the package.
