◆ CopyMode

enum OpenCVForUnity.UnityIntegration.OpenCVMatUtils.CopyMode

Enumeration to specify the data copy method.

Enumerator
PerPixel	Copies data on a per-pixel basis. If the input is 4 bytes per pixel and the output is 8 bytes per pixel, 4 bytes from the input are copied, and the remaining 4 bytes are filled with zeros. If the input is 8 bytes per pixel and the output is 4 bytes per pixel, only the first 4 bytes from the input are copied.
Contiguous	Copies data as a contiguous block of memory.

◆ CopyFromMat() [1/2]

static int OpenCVForUnity.UnityIntegration.OpenCVMatUtils.CopyFromMat	(	Mat	mat,
		IntPtr	intPtr )

static

Copies the data from an OpenCV Mat to an IntPtr.

This method transfers the data stored in an OpenCV Mat object into an IntPtr. It supports both continuous and non-continuous Mat objects:

If mat.isContinuous() is false and mat.dims() exceeds 2, the method will throw an exception, as non-continuous Mats with more than 2 dimensions are unsupported.
If mat.isContinuous() is true, the method can copy data from Mats with any number of dimensions.

The entire range of data managed by the Mat will be copied to the IntPtr. If you want to specify the exact range of data to copy, please use the method that accepts a length argument.

Note: This method operates on unmanaged memory, and incorrect usage can lead to unpredictable behavior, crashes, or data corruption. Ensure that the source pointer points to a valid memory region and that the specified length does not exceed the allocated memory size for that region. Additionally, as this method involves unmanaged memory, be cautious about potential security risks. Accessing memory beyond the intended range can lead to buffer overflows and may compromise application stability and security. It is highly recommended to perform validation checks on the pointer and the specified length.

Note: This method is specialized for copying a continuous range of data regardless of differences in types between the Mat and the array. Although its functionality is more limited compared to the Mat.get method, it offers improved performance for such operations.

Parameters

mat	The source Mat from which data will be copied. The Mat must not be disposed of or null.
intPtr	The destination IntPtr where the data will be copied. This pointer must reference a valid memory region.

Returns: The number of bytes copied from the Mat to the IntPtr.

Exceptions

ArgumentNullException	Thrown when mat is null.
ArgumentException	Thrown when `intPtr == IntPtr.Zero`. Thrown when `!mat.isContinuous() && mat.dims() > 2`.

◆ CopyFromMat() [2/2]

static int OpenCVForUnity.UnityIntegration.OpenCVMatUtils.CopyFromMat	(	Mat	mat,
		IntPtr	intPtr,
		int	length )

static

Copies the data from an OpenCV Mat to an IntPtr.

This method transfers the data stored in an OpenCV Mat object into an IntPtr. It supports both continuous and non-continuous Mat objects:

If mat.isContinuous() is false and mat.dims() exceeds 2, the method will throw an exception, as non-continuous Mats with more than 2 dimensions are unsupported.
If mat.isContinuous() is true, the method can copy data from Mats with any number of dimensions.

If the data size of the memory region pointed to by the IntPtr is smaller than the data size managed by the Mat, data will be copied up to the size of the IntPtr. If the data size of the memory region pointed to by the IntPtr is larger, data will be copied up to the size managed by the Mat.

Note: This method operates on unmanaged memory, and incorrect usage can lead to unpredictable behavior, crashes, or data corruption. Ensure that the source pointer points to a valid memory region and that the specified length does not exceed the allocated memory size for that region. Additionally, as this method involves unmanaged memory, be cautious about potential security risks. Accessing memory beyond the intended range can lead to buffer overflows and may compromise application stability and security. It is highly recommended to perform validation checks on the pointer and the specified length.

Note: This method is specialized for copying a continuous range of data regardless of differences in types between the Mat and the array. Although its functionality is more limited compared to the Mat.get method, it offers improved performance for such operations.

Parameters

mat	The source Mat from which data will be copied. The Mat must not be disposed of or null.
intPtr	The destination IntPtr where the data will be copied. This pointer must reference a valid memory region.
length	The number of elements, in terms of byte size, to copy from the source Mat to the destination IntPtr. The length represents the size in bytes, regardless of the actual type of data in the Mat or the destination.

Returns: The number of bytes copied from the Mat to the IntPtr.

Exceptions

ArgumentNullException	Thrown when mat is null.
ArgumentException	Thrown when `intPtr == IntPtr.Zero`. Thrown when `!mat.isContinuous() && mat.dims() > 2`.

◆ CopyFromMat< T >() [1/7]

static int OpenCVForUnity.UnityIntegration.OpenCVMatUtils.CopyFromMat< T >	(	Mat	mat,
		IntPtr	intPtr,
		int	length )

static

Copies the data from an OpenCV Mat to an IntPtr.

This method transfers the data stored in an OpenCV Mat object into an IntPtr. It supports both continuous and non-continuous Mat objects:

If mat.isContinuous() is false and mat.dims() exceeds 2, the method will throw an exception, as non-continuous Mats with more than 2 dimensions are unsupported.
If mat.isContinuous() is true, the method can copy data from Mats with any number of dimensions.

If the data size of the memory region pointed to by the IntPtr is smaller than the data size managed by the Mat, data will be copied up to the size of the IntPtr. If the data size of the memory region pointed to by the IntPtr is larger, data will be copied up to the size managed by the Mat.

Note: This method operates on unmanaged memory, and incorrect usage can lead to unpredictable behavior, crashes, or data corruption. Ensure that the source pointer points to a valid memory region and that the specified length does not exceed the allocated memory size for that region. Additionally, as this method involves unmanaged memory, be cautious about potential security risks. Accessing memory beyond the intended range can lead to buffer overflows and may compromise application stability and security. It is highly recommended to perform validation checks on the pointer and the specified length.

Note: This method is specialized for copying a continuous range of data regardless of differences in types between the Mat and the array. Although its functionality is more limited compared to the Mat.get method, it offers improved performance for such operations.

Note: This method is specialized for copying a continuous range of data regardless of differences in types between the array and the Mat. Although its functionality is more limited compared to the Mat.put method, it offers improved performance for such operations.

Template Parameters

T	The type of the elements represented by the IntPtr. This must be an unmanaged type (i.e., a type without references to managed objects) to allow for direct memory access.

Parameters

intPtr	The source IntPtr from which data will be copied. This pointer must reference a valid memory region.
mat	The destination Mat where the data will be copied. The Mat must not be disposed of or null.
length	The number of elements of type T to copy from the source IntPtr to the destination Mat.

Returns: The number of bytes copied from the IntPtr to the Mat.

Exceptions

ArgumentNullException	Thrown when mat is null.
ArgumentException	Thrown when `intPtr == IntPtr.Zero`. Thrown when `!mat.isContinuous() && mat.dims() > 2`.

static

Converts an OpenCV Mat to a Unity Texture2D.

This method converts an OpenCV Mat to a Unity Texture2D. Conversion is possible even when the number of bytes per pixel differs, such as from Mat(8UC1) to Texture2D(RGBA32). In the case of multi-channel color to 1-channel, it is converted to grayscale. Performance is optimal when the per-pixel data size and color order match, such as with Mat(8UC4) and Texture2D(RGBA32). If the texture format is not RGBA32, BGRA32, RGB24, Alpha8, or R8, the Texture2D.SetPixels32 and Texture2D.GetPixels32 methods are used. In such cases, it is recommended to use the pixels32Buffer argument to avoid repeated memory allocations.

Parameters

mat	The source Mat must be 2-dimensional, with a CvType of 'CV_8UC4' (RGBA), 'CV_8UC3' (RGB), or 'CV_8UC1' (GRAYSCALE). For other CvTypes or color orders, use MatToTexture2DRaw.
texture2D	The destination Texture2D must have the same size as the source Mat. The destination Texture2D supports the following formats. (Texture2D.SetPixels32)
flip	If `true`, the Mat is flipped before conversion. The default is `true`, as the Mat must be flipped to align with the coordinate system of the destination Texture2D image.
flipCode	Specifies how to flip the Mat: Vertical flipping of the image (flipCode == 0) to flip around the x-axis, horizontal flipping of the image (flipCode > 0, e.g., 1) to flip around the y-axis, and simultaneous horizontal and vertical flipping (flipCode < 0, e.g., -1) to flip around both axes. The default is `0`.
updateMipmaps	If `true`, mipmaps are recalculated after conversion. The default is `false`.
makeNoLongerReadable	If `true`, system memory copy of a texture is released. The default is `false`.

There are no specific requirements for the size or type of the Mat and Texture2D; data is copied up to the maximum size that fits within the data size of the mipmap of the destination Texture2D.

Parameters

mat	The source Mat must be 2-dimensional.
texture2D	The destination Texture2D.
mipLevel	The mipmap level to which the Mat will be converted. The level must be within the range supported by the destination Texture2D.
flip	If `true`, the Mat is flipped before copies. The default is `true`, as the Mat must be flipped to align with the coordinate system of the destination Texture2D image.
flipCode	Specifies how to flip the Mat: Vertical flipping of the image (flipCode == 0) to flip around the x-axis, horizontal flipping of the image (flipCode > 0, e.g., 1) to flip around the y-axis, and simultaneous horizontal and vertical flipping (flipCode < 0, e.g., -1) to flip around both axes. The default is `0`.
updateMipmaps	If `true`, mipmaps are recalculated after copies. The default is `false`.
makeNoLongerReadable	If `true`, system memory copy of a texture is released. The default is `false`.

Returns: Returns the number of bytes actually written to the destination Texture2D.

Exceptions

ArgumentNullException	Thrown when mat or texture2D is null.

static

Converts a Unity Texture2D to an OpenCV Mat.

This method converts a Unity Texture2D to an OpenCV Mat. Conversion is possible even when the number of bytes per pixel differs, such as from Texture2D(RGBA32) to Mat(8UC1). In the case of multi-channel color to 1-channel, it is converted to grayscale. Performance is optimal when the per-pixel data size and color order match, such as with Texture2D(RGBA32) and Mat(8UC4). If the texture format is not RGBA32, BGRA32, RGB24, Alpha8, or R8, the Texture2D.GetPixels32 methods are used.

Parameters

texture2D	The source Texture2D must have the same size as the destination Mat. The source Texture2D supports the following formats. (Texture2D.GetPixels32)
mat	The destination Mat must be 2-dimensional, with a CvType of 'CV_8UC4' (RGBA), 'CV_8UC3' (RGB), or 'CV_8UC1' (GRAYSCALE). For other CvTypes or color orders, use Texture2DToMatRaw.
flip	If `true`, the pixel data retrieved from the Texture2D is flipped before conversion. The default is `true`, as the pixel data must be flipped to align with the coordinate system of the destination Mat.
flipCode	Specifies how to flip the Textrue2D image: Vertical flipping of the image (flipCode == 0) to flip around the x-axis, horizontal flipping of the image (flipCode > 0, e.g., 1) to flip around the y-axis, and simultaneous horizontal and vertical flipping (flipCode < 0, e.g., -1) to flip around both axes. The default is `0`.
