im_pix_line draws a "pixel by pixel" imline and im_circle draws a "circle version" of imrect.
im_pix_line and im_circle is adopted from imline and im_circle,respectively. So either of the following methods to intall is OK:
- simple mode
Unzip the zip file, copy the whole folder, im_ext, to any place on matlab search path
- lazy mode
Unzip the zip file. copy im_ext\im_circle.m, im_ext\im_pix_line.m to %matlabroot\toolbox\images\imuitools copy im_ext\private\pixLineSymbol.m im_ext\private\defaultCircle.m to %matlabroot\toolbox\images\imuitools\private
IMPORTANT: im_pix_line uses LineTwoPnts.mexw32 to draw a discrete line. If the mex file is not available on your platform, please refer to
and then download the most up-to-date "fast bresenham" so that you can compile the appropriate mex file on your platform.
im_circle is almostly identical to imrect, for example:
figure, imshow('cameraman.tif') h = im_circle(gca, [110,60], 30); api = iptgetapi(h); api.setColor([1 0 0]); % IMPORTANT: use 'imline' here since the toolbox function % makeConstrainToRectFcn can only recognize one of the imline, imrect, impoint !!! fcn =makeConstrainToRectFcn('imrect',get(gca,'XLim'),get(gca,'YLim')); api.setDragConstraintFcn(fcn);
im_pix_line is almostly identical to imline, consider below example. (IMPORTANT: ensure t1_1.bmp is on your matlab search path)
imshow('t1_1.bmp'); im_pix_line(imgca,[189, 204],[195,214]); zoom(6); % You can try to drag the line at both end and the middle part.
Have fun:) For any suggestions/bug report, please email to email@example.com Thank you!
