runtimeType → Type

A representation of the runtime type of the object.

Methods

blur([int? strength]) → CdnPathBuilder

Performs Gaussian blur on result image. Strength is standard deviation (aka blur radius) multiplied by ten. Strength

build() → String

Returns the current CDN path as a string.

colorRecognition({int? numberOfColors}) → CdnPathBuilder

crop(int width, int height) → CdnPathBuilder

Adds top-left-aligned crop.

cropCenter(int width, int height) → CdnPathBuilder

Adds center-aligned crop.

cropCenterColor(int width, int height, String hexColor) → CdnPathBuilder

Adds center-aligned crop with a filled background.

cropColor(int width, int height, String hexColor) → CdnPathBuilder

Adds center-aligned crop with a filled background.

dimensionGuard(int dim) → void

dimensionsGuard(int width, int height) → void

fileInfoAsJson() → CdnPathBuilder

fileInfoAsJsonp() → CdnPathBuilder

flip() → CdnPathBuilder

Flips the image.

format(ImageFormat format) → CdnPathBuilder

Turn an image to one of the following formats: FORMAT_JPEG or FORMAT_PNG.

grayscale() → CdnPathBuilder

Adds a grayscale effect.

invert() → CdnPathBuilder

Inverts colors.

mirror() → CdnPathBuilder

Horizontally mirror image.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

preview([int? width, int? height]) → CdnPathBuilder

Reduces an image proportionally in order to fit it into given dimensions.

progressive(bool progressive) → CdnPathBuilder

Returns a progressive image. In progressive images, data are compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed while downloading over a slow connection allowing a reasonable preview after receiving only a portion of the data. The operation does not affect non-JPEG images; does not force image formats to JPEG. https://uploadcare.com/docs/transformations/image_transformations/#operation-progressive

quality(ImageQuality quality) → CdnPathBuilder

Image quality affects size of image and loading speed. Has no effect on non-JPEG images, but does not force format to JPEG.

resize(int width, int height) → CdnPathBuilder

Resizes width and height

resizeHeight(int height) → CdnPathBuilder

Resizes height, keeping the aspect ratio.

resizeWidth(int width) → CdnPathBuilder

Resizes width, keeping the aspect ratio.

scaleCrop(int width, int height) → CdnPathBuilder

Scales the image until one of the dimensions fits, then crops the bottom or right side.

scaleCropCenter(int width, int height) → CdnPathBuilder

Scales the image until one of the dimensions fits, centers it, then crops the rest.

sharp([int? strength]) → CdnPathBuilder

Performs sharpening on result image. This can be useful after scaling down.

toString() → String

A string representation of this object.

operator ==(Object other) → bool

The equality operator.
