FMX.Filter

• Up to Parent: FMX

Contains the FMX.Filter.Effects unit and various classes and types used in FireMonkey 2D bitmap effects rendered in hardware (GPU).

Units

FMX.Filter	Contains the FMX.Filter.Effects unit and various classes and types used in FireMonkey 2D bitmap effects rendered in hardware (GPU).
FMX.Filter.Effects	Defines the various FireMonkey filter effects, such as TDirectionalBlurEffect, TBandedSwirlTransitionEffect, and TFilterHueAdjust.

Classes

TFilter	TFilter is an abstract base class for every filter without any implementation.
TFilterClass	TFilterClass is the metaclass for the TFilter class.
TFilterRec	Record that holds filter attributes.
TShaderFilter	TShaderFilter is a special filter class that uses GPU shaders.
TShaderValueRec	Record that holds information about a shader value.

Routines

FillCategory	FillCategory returns a list of registered filter categories.
FillFiltersInCategory	FillFiltersInCategory returns a list of registered filters for the specified category.
FilterByName	Returns the TFilter descendant with the given name.
FilterClassByName	Returns the TFilterClass metaobject for the filter with the given name.
FilterRec	Creates a TFilterRec instance that has the fields initialized with the given values.
FilterValueRec	FilterValueRec creates a TShaderValueRec instance that has the fields initialized with the given values.
RegisterFilter	This is for internal use only.
VarFromBitmap	Returns the given TBitmap object as a Variant.
VarFromPoint	VarFromPoint returns the given TPointF object as a Variant.
VarFromPointXY	Returns a TPointF object given by its coordinates as a Variant.
VarIsBitmap	Returns True if the given variant holds a TBitmap object, and False otherwise.
VarIsPoint	Returns True if the given variant holds a TPointF object, and False otherwise.
VarToBitmap	Returns a TBitmap object if the given Variant holds one, and nil otherwise.
VarToPoint	Returns a TPointF object if the given Variant holds one, and nil otherwise.
VarToPointX	Returns the horizontal coordinate of a TPointF object if the given Variant holds a TPointF object, and nil otherwise.
VarToPointY	Returns the vertical coordinate of a TPointF object if the given Variant holds a TPointF object, and nil otherwise.

Types

TFilterClass	TFilterClass is the metaclass for the TFilter class.
TFilterRec	Record that holds filter attributes.
TShaderValueRec	Record that holds information about a shader value.
TShaderValueRecArray	Represents an array of TShaderValueRec used by FMX.Filter.TFilterRec to hold the shader values.
TShaderValueType	Enumeration that holds values that represents the type of a shader value held as a variant.

Variables

Filters	Variable that holds the class names of all the registered filters.
ShaderBitmap	Used internally; it cannot be changed by the user.
ShaderDevice	Used internally; it cannot be changed by the user.
TShaderValueRecArray	Represents an array of TShaderValueRec used by FMX.Filter.TFilterRec to hold the shader values.
