ApplyMatTransformations()

static Mat OpenCVForUnity.Extensions.SourceToMat.SourceToMatUtils.ApplyMatTransformations ( Mat inputMat, Mat rotated90Mat, bool flipVertical, bool flipHorizontal )

static

Applies horizontal/vertical flips and an optional 90-degree clockwise rotation to inputMat .

Parameters

inputMat	Input mat to transform.
rotated90Mat	Pre-allocated output for rotation. When null, rotation is skipped. Must be pre-allocated with swapped width/height and the same type as inputMat .
flipVertical	Whether to flip vertically.
flipHorizontal	Whether to flip horizontally.

Returns

rotated90Mat when rotation succeeds; otherwise inputMat .

Channels()

static int OpenCVForUnity.Extensions.SourceToMat.SourceToMatUtils.Channels ( SourceToMatColorFormat 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.

ColorConversionCodes()

static int OpenCVForUnity.Extensions.SourceToMat.SourceToMatUtils.ColorConversionCodes ( SourceToMatColorFormat srcType, SourceToMatColorFormat 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

TryCopyOrConvertColor()

static bool OpenCVForUnity.Extensions.SourceToMat.SourceToMatUtils.TryCopyOrConvertColor ( Mat sourceMat, Mat destinationMat, SourceToMatColorFormat sourceFormat, SourceToMatColorFormat destinationFormat )

static

Copies sourceMat into destinationMat , converting color when needed.

Parameters

sourceMat	Source mat.
destinationMat	Destination mat.
sourceFormat	Source color format.
destinationFormat	Destination color format.

Returns

true when a same-format copy or supported conversion succeeded; false when conversion is unsupported.
