Description

CreateBitmapFromLazarusResource is an overloaded TCustomBitmap function used to create and populate a bitmap with the content specified by the arguments to the routine.

The overloaded variants allow either a resource name (AName) or TLResource handle (AHandle) to be used to select the content for the bitmap. The variants with the AMinimumClass argument allow the class type for the graphic to be specified. TCustomBitmapClass is the default class type used in the overloaded variants.

CreateBitmapFromLazarusResource uses a temporary TLazarusResourceStream instance to load the content from the Lazarus resource.

CreateBitmapFromLazarusResource is used in the implementation of routines like LoadBitmapFromLazarusResourceHandle and GetDefaultGlyph (in ImgList.pp).
