以较高dpi保存matlab图形文件

函数 gcf 只返回当前图形句柄,因此如果通过打开.fig文件 openfig ,应该有用。以下示例以900 dpi的分辨率创建两个相同的TIFF文件,一个在保存.fig之前,另一个在加载.fig之后:

surf(peaks);           % Create a surface plot
print(gcf, 'before_save.tif', '-dpng', '-r900');  % Save figure as an image
savefig('peaks.fig');  % Save figure in a .fig file
close(gcf);            % Close figure

openfig('peaks.fig');  % Recreate figure from .fig file
print(gcf, 'after_save.tif', '-dpng', '-r900');  % Save new figure as an image
