UnmanagedImageCollect8bppPixelValues Method

Collect pixel values from the specified list of coordinates.

Namespace:  Accord.Imaging
Assembly:  Accord.Imaging (in Accord.Imaging.dll) Version: 3.8.0
public byte[] Collect8bppPixelValues(
	List<IntPoint> points
Request Example View Source


Type: System.Collections.GenericListIntPoint
List of coordinates to collect pixels' value from.

Return Value

Type: Byte
Returns array of pixels' values from the specified coordinates.
UnsupportedImageFormatExceptionUnsupported pixel format of the source image. Use Collect16bppPixelValues() method for images with 16 bpp channels.

The method goes through the specified list of points and for each point retrievs corresponding pixel's value from the unmanaged image.

Note Note
For grayscale image the output array has the same length as number of points in the specified list of points. For color image the output array has triple length, containing pixels' values in RGB order.

Note Note
The method does not make any checks for valid coordinates and leaves this up to user. If specified coordinates are out of image's bounds, the result is not predictable (crash in most cases).

Note Note
This method is supposed for images with 8 bpp channels only (8 bpp grayscale image and 24/32 bpp color images).
