RichViewMaxPictureCount Global Variable
RichViewMaxPictureCount: Integer = 100;
(introduced in version 16)
Specifies the maximal count of images stored in TCustomRichView in an "active" form, i.e. as TGraphic objects. Other pictures are "deactivated", i.e. stored in a memory stream until they are requested. This activation/deactivation allows saving GDI resources and memory.
Changes of value of this property do not affect TRichView components created before the change.
