图像太大，无法放入屏幕（MATLAB） [英] image is too big to fit in the screen (MATLAB)

问题描述

我知道这只是一个警告而且它不会影响代码..但我的问题是我需要以实际尺寸显示图像而不缩小..这是可能的 imshow 函数是否有任何参数可以执行此操作？

I know that it is just a warning and it will not affect the code .. but my problem is that I need to show the image in its real size without any zooming out .. is that possible in imshow function are there any parameters that do this?

谢谢大家

推荐答案

一个应该有效的解决方案是显示图像，然后更改轴限制，以便每个图像像素都有一个屏幕像素：

One solution that should work is to display the image and then change the axes limits so that there is one screen pixel for every image pixel:

%# read an image and make it large
img = imread('autumn.tif');
img = repmat(img,[10,10]);

%# turn off the warning temporarily, we're going to fix the problem below
%# Note that in R2011b, the warning ID is different!
warningState = warning('off','Images:initSize:adjustingMag');
figure
imshow(img)
warning(warningState);


%# get axes limits in pixels
set(gca,'units','pixels')
pos = get(gca,'position')

%# display the top left part of the image at magnification 100%
xlim([0.5 pos(3)-0.5]),ylim([0.5 pos(4)-0.5])

现在你可以选择指针（平移工具）并根据需要移动图像。

Now you can select the hand (pan tool) and move the image around as needed.
