PictureEffectsRaw Xojo Plugin

PolarCoordinatesEffectRaw Class (console safe)

Use this class to transform polar coordinates to rectangular coordinates or rectangular coordinates to polar coordinates.

This effect is sometimes used to map images taken by a 360 degree ceiling camera to image that humans can understand.

Supports:
  • 8 bit per channel bitmaps

  • 16 bit per channel bitmaps

  • RGB color spaces

  • Gray color spaces

  • CMYK color spaces

  • Synchronous and asynchronous modes supported



    • This class supports use of multiple CPU cores.

    class PolarCoordinatesEffectRaw implements

    IRawBitmapProcessor

    IRawBitmapProcessorAsync

    Properties

    AsyncCompleted (Inherited) (console safe) Returns true if asynchronous execution has completed, else false.
    AsyncResult (Inherited) (console safe) Returns the result bitmap of asynchronous execution.
    BackColor (console safe) Sets back color to fill the area around the circle when doing rectangular to polar transform.
    CPUCoreCount (Inherited) (console safe) Returns number of detected CPU cores on the running machine.
    Canceled (Inherited) (console safe) If this one returns true then the effects execution was canceled by a Progress handler.
    ErrorCode (Inherited) (console safe) Returns error code after applying the effect. This value is a Constant defined in the PictureEffectsRawError module.
    FlipMapping (console safe) Sets direction of the mapping
    ForceThreads (Inherited) (console safe) Forces use of thread when set to true even when using only one CPU core.
    MaximumCPUCores (Inherited) (console safe) Read only property where each effect can report maximum CPU cores it supports.
    MultiprocessingHint (Inherited) (console safe) Use this property to fine tune CPU usage for this algorithm. By default this property is set to zero (Automatic). This property accepts all constants that are defined in this class.
    ProgressHandler (Inherited) (console safe) Use this property to use a progress class to get progress feedback from this function. This class must be a class that Implements the IProgressHandler Interface which is defined in this plugin.
    RectangularToPolar (console safe) Decides if doing polar to rectangular or rectangular to polar transform.

    Methods

    Apply (console safe) Applies the effect on a RawBitmap image with parameters that have been set on the class instance.
    Apply (console safe) Applies the effect on a RawBitmap image taking in parameters to configure the effect.
    ApplyAsync (console safe) Applies the effect asynchronously on a RawBitmap image with parameters that have been set on the class instance.
    Cancel (Inherited) (console safe) Cancels processing and waits for threads to come to full stop when in asynchronous execution.
