IMAGESCALE(3) 1 IMAGESCALE(3)
imagescale - Scale an image using the given new width and height
SYNOPSIS
resource imagescale (resource $image, int $new_width, [int $new_height = -1], [int $mode = IMG_BILINEAR_FIXED])
DESCRIPTION
imagescale(3) scales an image using the given interpolation algorithm.
PARAMETERS
o $
image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).
o $new_width
- The width to scale the image to.
o $new_height
- The height to scale the image to. If omitted or negative, the aspect ratio will be preserved.
Caution
You should always provide the height if using PHP 5.5.18 or earlier, or PHP 5.6.2 or earlier, as the aspect ratio calcula-
tion was incorrect.
o $mode
- One of IMG_NEAREST_NEIGHBOUR, IMG_BILINEAR_FIXED, IMG_BICUBIC, IMG_BICUBIC_FIXED or anything else (will use two pass).
RETURN VALUES
Return the scaled image resource on success or FALSE on failure.
