Constructs a new PixelMemory object with memory allocated by GlobalAlloc in the provided pointer.

Namespace:  Atalasoft.Imaging.Memory
Assembly:  Atalasoft.dotImage (in Atalasoft.dotImage.dll) Version: 11.0.0.0.0.297 (.NET 4.5.2, x86)
Syntax
public GlobalAllocPixelMemory(
	IntPtr memoryStart,
	int numBytes,
	int height,
	int rowStride,
	int offsetToFirstScanline
)

Parameters

memoryStart
Type: SystemIntPtr
A pointer to the start at memory. MemoryStart must be allocated by GlobalAlloc.
numBytes
Type: SystemInt32
The total number of bytes occupied by this image. Typically this will be height * rowstride, but it could be larger if there is space needed before or after the last scanline.
height
Type: SystemInt32
The height of the image.
rowStride
Type: SystemInt32
The number of bytes in a scanline rounded up to the next multiple of 4.
offsetToFirstScanline
Type: SystemInt32
An offset to the first scanline in the image. Typically, this is zero, but in some images, there is header information before the first scanline
Remarks
This method will throw if memoryStart is not the start of a valid block or was not allocated by GlobalAlloc or was not allocated with specified size.
