ImageManipConfig
This message can is used for cropping, warping, rotating, resizing, etc. an image in runtime. It can be sent from host/Script node to either Camera or ImageManip.This message will reconfigure the whole config of the node, meaning you need to set all settings, not just the setting you want to change.

function
ImageManipConfig & addCrop(uint32_t x, uint32_t y, uint32_t w, uint32_t h)Crops the image to the specified rectangle
Parameters
- x: X coordinate of the top-left corner

- w: Width of the rectangle
- h: Height of the rectangle
function
ImageManipConfig & addCrop(dai::Rect rect, bool normalizedCoords)Crops the image to the specified rectangle
Parameters
- rect: Rect to crop
- normalizedCoords: If true, the coordinates are normalized to range [0, 1] where 1 maps to the width/height of the image
function
ImageManipConfig & addCropRotatedRect(dai::RotatedRect rotatedRect, bool normalizedCoords)Crops the image to the specified (rotated) rectangle
Parameters
- rect: RotatedRect to crop
- normalizedCoords: If true, the coordinates are normalized to range [0, 1] where 1 maps to the width/height of the image
function
ImageManipConfig & addScale(float scaleX, float scaleY)Rescales the image using the specified factors
Parameters
- scaleX: Scale factor for the X axis
- scaleY: Scale factor for the Y axis. If not specified, scaleY is set to the same value as scaleX
function
ImageManipConfig & addRotateDeg(float angle)Rotates the image around its center by the specified angle in degrees
Parameters
- angle: Angle in radians
function
ImageManipConfig & addRotateDeg(float angle, Point2f center)Rotates the image around the specified point by the specified angle in degrees
Parameters

Parameters
- matrix: an array containing a 2x2 matrix representing the affine transformation
function
ImageManipConfig & addTransformPerspective(std::array< float, 9 > matrix)Applies a perspective transformation to the image
Parameters

function
ImageManipConfig & addTransformFourPoints(std::array< dai::Point2f, 4 > src, std::array< dai::Point2f, 4 > dst, bool normalizedCoords)Applies a perspective transformation to the image
Parameters
- src: Source points
- dst: Destination points
- normalizedCoords: If true, the coordinates are normalized to range [0, 1] where 1 maps to the width/height of the image
function
ImageManipConfig & setOutputSize(uint32_t w, uint32_t h, ResizeMode mode)Sets the output size of the image
Parameters
