Order Property (RasterImage)








Leadtools Namespace > RasterImage Class : Order Property
Gets or sets the color order of this RasterImage.
Syntax

'Declaration

'Usage
 

Dim instance As RasterImage

instance.Order = value
 
value = instance.Order
public RasterByteOrder Order {get; set;}
@property (nonatomic, assign) LTRasterByteOrder order
public RasterByteOrder getOrder()
 <br/>get_Order();<br/>set_Order(value);<br/>Object.defineProperty('Order'); 
public:
property RasterByteOrder Order {
   RasterByteOrder get();
   void set (    RasterByteOrder value);
}

Property Value

The color order of this RasterImage.
Remarks

The RasterImage object supports storing the image data in one of the following color orders:

Order Notes
RasterByteOrder.Rgb The image data contains the color in the RGB order. For example, for 24-bits per pixel images the data is stored as the 3 bytes representing the red, green and blue component respectively. Palettized images (with bits per pixel less than or equal to 8) will also report a byte order of RGB although the image data stored is really indices into the palette.

16-bit bitmaps use 5 bits for R, G and B components and one bit for alpha
RasterByteOrder.Bgr The image data contains the color in the BGR order. For example, for 24-bits per pixel images the data is stored as the 3 bytes representing the blue, green and red component respectively.
RasterByteOrder.Rgb565 The image data contains the color in RGB color order with 5 bits for red and blue component and 6 bits for green component (16 bits per pixel). There is no alpha information.
RasterByteOrder.Gray The image data contains the grayscale colors. For 12 and 16-bits per pixel images, the image data contains the grayscale values of the pixel, for 8-bits per pixel gray scale images, the image data contains an index into the grayscale palette.
RasterByteOrder.Romm The image data is compressed in memory using ROMM. Only valid for 24-bits per pixel images.
