Question

basically, i am supposed to create a image with circles and lines... not using plot function. because the final output is to pop out by imshow().or image().or imagesc()... and the created image will contiune the color processing.

Answer 1

最简单的方式是按惯例提取数据,然后使用getframe,以 gr清数据的形象。

EDIT: I don t have time for much detail, but look at the following:

line: http://www.mathworks.co.uk/help/techdoc/ref/line.html
circle: http://www.mathworks.com/matlabcentral/fileexchange/2876
axis properties: http://www.mathworks.co.uk/help/techdoc/ref/axes_props.html (You may want to set Visible , off , Position , [0 0 1 1], DataAspectRatio , [1 1 1])
getframe: http://www.mathworks.co.uk/help/techdoc/ref/getframe.html

MATLAB的帮助确实非常有用。

Answer 2

如果你试图直接从圆形图像上提取线和圈子(胶合仪表),那么就可查Bresenham Line-dranel及其圈子变量。

我确信,你可以在FEX上找到现有的执行情况。

另一种可能性是显示图像(IMSHOW, IMAGESC, ),使用平地功能(PLOT, LINE, ......),然后用GETFRAME作为图像再次涂 gr该图:。

Answer 3

利用“试金”功能,并具体说明“库拉”参数。 i.e.

rectangle( Position ,[0 0 100 100], Curvature ,[1 1])

这显然是反省性的,但在马特拉布,坦哲是你用来收集智慧和圈子的职能。

这里是适当的数学工程:
