This includes translation and Rotation Transformation. This is a very basic thing, that is, to extend the vector to a space that can be transformed. For example, to transform a three-dimensional color vector, it is extended into a five-dimensional space. In my project, many images only have a set of transformation parameters and a reference pointing to the elements, that is, you need to use the transformation parameters to convert the element coordinates to the real display system coordinate

volumes of B and A to R respectively. The total shear volumes are the total shear volumes of R. Expressed: R = g * m21 + B * m31 + A * M41; G = r * m12 + B * M32 + A * M42; B = r * M13 + G * M23 + A * m43; A = r * m14 + G * M24 + B * m34; 3. Color rotation: The description of color rotation is complex, that is, in the image pixel, two of them are used to calculate the result around the other one according to a certain angle, is the color rotation.

However, it increases the inertia of the arm and the load on the joints, and is suitable for situations where the imbalance torque is small.2) Spring balancing mechanism: the principle 2b shows that the arm's unbalanced torque isM1 = M11-M12 = mglcos gamma-iaMedium M11-static unbalanced moment;M12-inertial moment;I -- moment of inertia of the arm against the joint axis;A: average acceleration of

, but qpainter also supports coordinate transformation. You can use the qpainter: Scale () function to perform proportional transformation. UseThe qpainter: Rotate () function performs Rotation Transformation. Use the qpainter: translate () function for translation conversion.Number, qpainter: shear () function to distort the image. All transformation matrices can be obtained through the qpainter: wordmatrix () function.Output. Different transformation matrices can be saved using stacks.Use qpai
