public class DEVMODE
extends Struct
```
Contains information about the initialization and environment of a printer or a display device.
Member documentation
- dmDeviceName – A zero-terminated character array that specifies the "friendly" name of the printer or display; for example, "PCL/HP LaserJet" in the case of PCL/HP LaserJet. This string is unique among device drivers. Note that this name may be truncated to fit in the dmDeviceName array.
- dmSpecVersion – the version number of the initialization data specification on which the structure is based. To ensure the correct version is used for any operating system, use GDI32.DM_SPECVERSION.
- dmDriverVersion – the driver version number assigned by the driver developer
- dmSize – specifies the size, in bytes, of the DEVMODE structure, not including any private driver-specific data that might follow the structure's public members. Set this member to DEVMODE.SIZEOF to indicate the version of the DEVMODE structure being used.
- dmDriverExtra – contains the number of bytes of private driver-data that follow this structure. If a device driver does not use device-specific information, set this member to zero.
- dmFields – specifies whether certain members of the DEVMODE structure have been initialized. If a member is initialized, its corresponding bit is set otherwise the bit is clear. A driver supports only those DEVMODE members that are appropriate for the printer or display technology.
- dmOrientation – for printer devices only
- dmPaperSize – for printer devices only
- dmPaperLength – for printer devices only
- dmPaperWidth – for printer devices only
- dmScale – for printer devices only
- dmCopies – for printer devices only
- dmDefaultSource – for printer devices only
- dmPrintQuality – for printer devices only
- dmPosition – for display devices only, a POINTL structure that indicates the positional coordinates of the display device in reference to the desktop area. The primary display device is always located at coordinates (0,0).
- dmDisplayOrientation – for display devices only, the orientation at which images should be presented. If GDI32.DM_DISPLAYORIENTATION is not set, this member must be zero. If GDI32.DM_DISPLAYORIENTATION is set, this member must be one of the following values:
  GDI32.DMDO_DEFAULT, GDI32.DMDO_90, GDI32.DMDO_180, GDI32.DMDO_270
  To determine whether the display orientation is portrait or landscape orientation, check the ratio of dmPelsWidth to dmPelsHeight.
- dmDisplayFixedOutput – for fixed-resolution display devices only, how the display presents a low-resolution mode on a higher-resolution display. For example, if a display device's resolution is fixed at 1024 x 768 pixels but its mode is set to 640 x 480 pixels, the device can either display a 640 x 480 image somewhere in the interior of the 1024 x 768 screen space or stretch the 640 x 480 image to fill the larger screen space. If GDI32.DM_DISPLAYFIXEDOUTPUT is not set, this member must be zero. If GDI32.DM_DISPLAYFIXEDOUTPUT is set, this member must be one of the following values:
  GDI32.DMDFO_DEFAULT, GDI32.DMDFO_CENTER, GDI32.DMDFO_STRETCH
- dmColor – for printer devices only
- dmDuplex – for printer devices only
- dmYResolution – for printer devices only
- dmTTOption – for printer devices only
- dmCollate – for printer devices only
- dmFormName – for printer devices only
- dmLogPixels – the number of pixels per logical inch
- dmBitsPerPel – specifies the color resolution, in bits per pixel, of the display device (for example: 4 bits for 16 colors, 8 bits for 256 colors, or 16 bits for 65,536 colors)
- dmPelsWidth – specifies the width, in pixels, of the visible device surface
- dmPelsHeight – specifies the height, in pixels, of the visible device surface
- dmDisplayFlags – specifies the device's display mode, one or more of:
  GDI32.DM_INTERLACED, GDI32.DMDISPLAYFLAGS_TEXTMODE
- dmNup – for printer devices only
- dmDisplayFrequency – specifies the frequency, in hertz (cycles per second), of the display device in a particular mode. This value is also known as the display device's vertical refresh rate.
  When you call the User32.EnumDisplaySettingsEx(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DEVMODE, int) function, the dmDisplayFrequency member may return with the value 0 or 1. These values represent the display hardware's default refresh rate. This default rate is typically set by switches on a display card or computer motherboard, or by a configuration program that does not use display functions such as ChangeDisplaySettingsEx.
- dmICMMethod – for printer devices only
- dmICMIntent – for printer devices only
- dmMediaType – for printer devices only
- dmDitherType – for printer devices only
- dmReserved1 – not used; must be zero
- dmReserved2 – not used; must be zero
- dmPanningWidth – this member must be zero
- dmPanningHeight – this member must be zero
