Description

TCustomMap is the abstract base class for all two-dimensional mapped data structures in Graphics32, including TCustomBitmap32, ordinal maps (TByteMap, TFloatMap), and vector maps (TVectorMap). It establishes standard Width and Height management, buffer resizing routines, and dimension change notifications via OnResize.

Constructors

Name	Description
Create	Initializes a new TCustomMap instance, optionally setting initial dimensions.

Methods

Name	Description
Clear	Clears the map content or resets buffer memory.
Delete	Sets map dimensions to zero and releases allocated buffer memory.
Empty	Returns True if either Width or Height is zero.
Resized	Triggers internal size change processing and fires OnResize.
SetSize	Changes the map dimensions to specified width and height.
SetSizeFrom	Copies dimensions from another map object or persistent container.
ChangeSize	Protected virtual method that performs buffer allocation and dimension updates.
SetHeight	Protected setter method for the Height property.
SetWidth	Protected setter method for the Width property.

Properties

Name	Type	Description
Height	Integer	Vertical dimension of the map in units or pixels.
Width	Integer	Horizontal dimension of the map in units or pixels.
