static ReplaceColor replaceColor(string $toColor, int $tolerance = null, string $fromColor = null)

Maps an input color and those similar to the input color to corresponding shades of a specified output color, taking luminosity and chroma into account, in order to recolor an object in a natural way.

More highly saturated input colors usually give the best results. It is recommended to avoid input colors approaching white, black, or gray.

Parameters

Name Type Description
$toColor string The HTML name or RGB/A hex code of the target output color.
$tolerance int The tolerance threshold (a radius in the LAB color space) from the input color, representing the span of colors that should be replaced with a correspondingly adjusted version of the target output color. Larger values result in replacing more colors within the image. The more saturated the original input color, the more a change in value will impact the result (Server default: 50).
$fromColor string The HTML name or RGB/A hex code of the base input color to map (Server default: the most prominent high-saturation color in the image).

Return Value

ReplaceColor

ReplaceColor

static EffectAction recolor(array ...$colorMatrix)

Converts the colors of every pixel in an image based on the supplied color matrix, in which the value of each color channel is calculated based on the values from all other channels (e.g. a 3x3 matrix for RGB, a 4x4 matrix for RGBA or CMYK, etc).

For every pixel in the image, take each color channel and adjust its value by the specified values of the matrix to get a new value.

Parameters

Name Type Description
...$colorMatrix array The matrix of colors.

Return Value

EffectAction

static StrengthEffectAction sharpen(int $strength = null)

Applies a sharpening filter to the image.

Parameters

Name Type Description
$strength int The strength of the filter. (Range: 1 to 2000, Server default: 100)

Return Value

StrengthEffectAction

static StrengthEffectAction unsharpMask(int $strength = null)

Applies an unsharp mask filter to the image.

Parameters

Name Type Description
$strength int The strength of the filter. (Range: 1 to 2000, Server default: 100)

Return Value

StrengthEffectAction

static LevelEffectAction opacityThreshold(int $level = null)

Causes all semi-transparent pixels in an image to be either fully transparent or fully opaque.

Each pixel with an opacity lower than the specified threshold value is set to an opacity of 0%. Each pixel with an opacity greater than the specified threshold is set to an opacity of 100%. For example, setting opacity_threshold:0 makes all pixels non-transparent, while opacity_threshold:100 makes all semi-transparent pixels fully transparent. Note: This effect can be a useful solution when PhotoShop PSD files are delivered in a format supporting partial transparency, such as PNG, and the results without this effect are not as expected.

Parameters

Name Type Description
$level int The level of the threshold. (Range: 1 to 100, Server default: 50)

Return Value

LevelEffectAction

static Opacity opacity(float $level)

Adjusts the opacity of the image and makes it semi-transparent.

Parameters

Name Type Description
$level float The level of opacity. 100 means opaque, while 0 is completely transparent. (Range: 0 to 100)

Return Value

Opacity
