$image = new Imagick('input.jpg'); $image->setInterlaceScheme(Imagick::INTERLACE_PLANE); $image->writeImage('output.jpg');This code loads an image named "input.jpg" using the Imagick class. The setInterlaceScheme function is called with the constant Imagick::INTERLACE_PLANE, which sets the interlace scheme to a progressive format. Finally, the modified image is saved to the file "output.jpg". The Imagick package library is part of the PHP core, and as such does not require any additional installation.
