The Crop command gives confusing dimension

[Xiaoxiong Xing]

I have an image that is 2048*2048. When I run the following macros:

makeRectangle(304, 304, 1450, 1450);
run("Crop");

it then results in an image of 1450*1450. Why not (1450-303)*(1450-303)?

Hi Xing,

The second pair of parameters are the width and height of the ROI
rectangle you make, hence when the image is cropped, you get a new image
starting at pixel 304,304 in the original - with width and height of 1450.

Hope that helps,
Ed
