DisplayMode Enumeración

Definición

Define identificadores que indican los modos de presentación que utiliza ByteViewer.

public enum class DisplayMode
public enum DisplayMode
type DisplayMode = 
Public Enum DisplayMode
Herencia
DisplayMode

Campos

Ansi 2

Presentación en formato ANSI.

Auto 4

Modo de presentación que selecciona automáticamente un modo de presentación. En este modo, se examinan los bytes para determinar si son hexadecimales o imprimibles. Si los bytes tienen formato hexadecimal, se selecciona el modo Hexdump. Si los caracteres coinciden con un juego de caracteres imprimibles, se ejecuta una prueba para seleccionar automáticamente el modo de presentación Ansi o Unicode.

Hexdump 1

Presentación en formato hexadecimal.

Unicode 3

Presentación en formato Unicode.
