ImageEn, unit iexAcquire

TIEAcquireParams.PixelType

TIEAcquireParams.PixelType


Declaration

property PixelType: TIEAcquirePixelType; (Read/Write)


Description

Specifies the type of pixel data that a scanner is capable of acquiring.

Note:
 Not supported for DCIM retrieval (i.e. when SelectedAcquireSource.Api = ieaDCIM)
 Passing ieapOther as the PixelType will acquire using the default/current properties

Valid values are:
Value Description
ieapMonochrome Black & white (1 bit)
ieap8BitGrayScale Gray scale (8 bit)
ieap16BitGrayScale Gray scale (16 bit)
ieapFullColor Full RGB (24 bit)
ieapFullColor16 Full RGB (48 bit)
ieapOther Other pixel formats (that are not supported by ImageEn)

Note: If you set PixelType to a value that is not supported by your device, it will be set to the closest match. You can determine what formats the device supports by using IsPixelTypeSupported


Example

// Acquire a black/white (1bit) image
ImageEnView1.IO.AcquireParams.PixelType := ieapMonochrome;
ImageEnView1.IO.AcquireParams.VisibleDialog := False;
ImageEnView1.IO.Acquire();

// Acquire a gray scale (8bit) image
ImageEnView1.IO.AcquireParams.PixelType.CurrentValue := ieap8BitGrayScale;
ImageEnView1.IO.AcquireParams.VisibleDialog := False;
ImageEnView1.IO.Acquire();

// Acquire a full RGB (24bit) image
ImageEnView1.IO.AcquireParams.PixelType.CurrentValue := ieapFullColor;
ImageEnView1.IO.AcquireParams.VisibleDialog := False;
ImageEnView1.IO.Acquire();
