ApplyMatTransformations()

static Mat OpenCVForUnity.UnityUtils.Helper.Source2MatHelperUtils.ApplyMatTransformations ( Mat inputMat, Mat rotated90Mat, bool flipVertical, bool flipHorizontal )

static

Apply Mat transformations based on IMatTransformationProvider settings.

Parameters

inputMat	Input mat to transform.
rotated90Mat	The rotated Mat output. If null, no rotation will be performed. If not null, must have the same CVType as inputMat and dimensions swapped (width=height, height=width).
flipVertical	Whether to flip vertically.
flipHorizontal	Whether to flip horizontally.

Returns

Transformed mat.

The rotated90Mat parameter must be pre-allocated with the correct dimensions and CVType to prevent any memory allocation during rotation. If rotated90Mat is null, the method will return inputMat without rotation.

Channels()

static int OpenCVForUnity.UnityUtils.Helper.Source2MatHelperUtils.Channels ( Source2MatHelperColorFormat type )

static

Gets the number of channels for the specified color format.

Parameters

type	The color format

Returns

Number of channels. Returns 1 for GRAY, 3 for RGB/BGR, 4 for RGBA/BGRA. Returns 4 for unknown formats.

Channel counts for each color format:

• GRAY: 1 channel
• RGB/BGR: 3 channels
• RGBA/BGRA: 4 channels

ColorConversionCodes()

static int OpenCVForUnity.UnityUtils.Helper.Source2MatHelperUtils.ColorConversionCodes ( Source2MatHelperColorFormat srcType, Source2MatHelperColorFormat dstType )

static

Gets the OpenCV color conversion code needed for converting between two color formats.

Parameters

srcType	The source color format
dstType	The destination color format

Returns

OpenCV color conversion code. Returns -1 if conversion is not possible.

Supported color format conversions:

• GRAY ⇔ RGB/BGR/RGBA/BGRA
• RGB ⇔ GRAY/BGR/RGBA/BGRA
• BGR ⇔ GRAY/RGB/RGBA/BGRA
• RGBA ⇔ GRAY/RGB/BGR/BGRA
• BGRA ⇔ GRAY/RGB/BGR/RGBA
