TBitMap

Represents an image in ram.

Declaration

Source position: agraphics.pas line 95

type TBitMap = record

  BytesPerRow: Word;

  

Width of a line it Bytes (To get the width of the Bitmap in pixels you have to multiply this value with 8 and divide by the Depth.)

  Rows: Word;

  

Number of lines in the Bitmap

  Flags: Byte;

  

Flags for the bitmap when created on AllocBitmap (BMF_*)

  Depth: Byte;

  

Number of Bitplanes

  pad: Word;

  

Padding byte

  Planes: array [0..7] of PByte;

  

Pointer to the bitplanes. Depth defines how many pointers

end;

Description

Drawing to a Bitmap is mostly done by drawing on a TRastPort with the linked Bitmap TRastPort.Bitmap.
