TdxGPImageCodecBMP.CanLoadStream(TStream) Method

Identifies if the codec can load an image stored in the specified stream.

Declaration

class function CanLoadStream(AStream: TStream): Boolean; override;

Parameters

Name	Type
AStream	TStream

Returns

Type
Boolean

Remarks

You can call this class function and pass a stream as the AStream parameter to identify if the stream contains a device-independent bitmap (that is, DIB or BMP) image that starts from its current position. The class function returns True if the stream’s content at the current position starts with the $42$4D bytes that correspond to the ‘BM’ ASCII characters; otherwise, False.

Note

The CanLoadStream function restores the state the stream had prior to an attempt to read the first two bytes regardless of its success.
