Imagick::setImageType

(PECL imagick 2, PECL imagick 3)

Imagick::setImageType — Sets the image type

Description

public function Imagick::setImageType(int $image_type): bool

Converts the image to the given type, which combines a color model with the presence or absence of an alpha channel. Depending on the type, this may change the colorspace, quantize the colors, or change whether the image has an alpha channel.

Imagick::setImageType() modifies the image itself. To set the type that subsequent images are written with instead, use Imagick::setType().

Parameters

image_type

One of the imagick::IMGTYPE_* constants. imagick::IMGTYPE_UNDEFINED and imagick::IMGTYPE_OPTIMIZE convert nothing, but are still recorded on the image.

Return Values

Returns true on success.
