Image Processing Operations: Grayscale Conversion, Rotation, Sharpening, and Geometric Drawing

This program performs various image processing operations including grayscale conversion, rotation, sharpening, and drawing geometric shapes (circles, ellipses, lines) on images. Implementation requires entering specific parameter expressions in input fields. Example expressions: Line drawing: x1=20,y1=15,x2=150,y2=100; Circle: x=100,y=100,r=20; Ellipse: x=100,y=100,a=16,b=9; Rotation: angle=30(degrees),ax=100,ay=90; Sharpening: factor=80. The core algorithms utilize matrix transformations for geometric operations and convolution kernels for sharpening.
