(No version information available, might only be in Git)

Imagick::extentImageSet image size

Descrierea

bool Imagick::extentImage ( int $width , int $height , int $x , int $y )

Comfortability method for setting image size. The method sets the image size and allows setting x,y coordinates where the new area begins. Această metodă este disponibilă dacă Imagick a fost compilat cu ImageMagick de versiunea 6.3.1 sau ulterior.

Precauţie

Prior to ImageMagick 6.5.7-8 (1623), $x was positive when shifting to the left and negative when shifting to the right, and $y was positive when shifting an image up and negative when shifting an image down. Somewhere betwen ImageMagick 6.3.7 (1591) and ImageMagick 6.5.7-8 (1623), the axes of $x and $y were flipped, so that $x was negative when shifting to the left and positive when shifting to the right, and $y was negative when shifting an image up and positive when shifting an image down. Somewhere between ImageMagick 6.5.7-8 (1623) and ImageMagick 6.6.9-7 (1641), the axes of $x and $y were flipped back to pre-ImageMagick 6.5.7-8 (1623) functionality.

This function cannot handle images with a transparent background. Use setImageExtent instead.
