MaplyColorRampGenerator

Objective-C

@interface MaplyColorRampGenerator : NSObject

Swift

class MaplyColorRampGenerator

The color ramp generator will take a set of color values and generate a linear ramp of those colors in an output image. You typically feed the color ramp image into a shader.

  • Undocumented

    Declaration

    Objective-C

    @property (nonatomic) bool stretch

    Swift

    var stretch: Int32 { get set }

  • Add a color as a hex value.

    Declaration

    Objective-C

    Swift

    func addHexColor(_ hexColor: Int32)

  • This color has an alpha too

    Declaration

    Objective-C

    - (void)addHexColorWithAlpha:(int)hexColor;

    Swift

    func addHexColor(withAlpha hexColor: Int32)

  • A color that’s present in only one entry

    Declaration

    Objective-C

    - (void)addSingleEntryColor:(id)color;

    Swift

    func addByteRed(_ red: Int32, green: Int32, blue: Int32, alpha: Int32)

  • Generate the image with the color ramp in it

    Declaration

    Objective-C

    - (id)makeImage:(CGSize)size;

    Swift

    func makeImage(_ size: Any!) -> Any!

  • Get a list of colors (rather than generating an image)
