Methods

Copies the original image pixels into a cached image buffer, with optional color conversion in the case where the original image is grayscale.

public static IplImage EnsureColorCopy(IplImage output, IplImage image)

output IplImage: The current cached image buffer. If the value is null, or if the cached image parameters do not match the size of the source image, a new image buffer will be allocated.
image IplImage: The image storing the original pixel values.

IplImage: An IplImage object matching the size and bit depth of image pixels, and where the number of channels is always three. Pixel values from image will be either copied or converted from grayscale to BGR, depending on the number of channels.

Ensures the cached image buffer is allocated and has the specified size and format parameters.

public static IplImage EnsureImageFormat(IplImage output, Size size, IplDepth depth, int channels)

output IplImage: The current cached image buffer. If the value is null, or if the cached image parameters do not match the specified size and format, a new image buffer will be allocated.
size Size: The pixel-accurate size of the image.
depth IplDepth: The bit depth format for each pixel in the image.
channels int: The number of channels in the image.

IplImage: An IplImage object matching the specified size and format parameters. If output matches all the parameters, the same reference is returned without modification.
