Question

我正在尝试从数字生成PDF文件，以便在MATLAB中进行缩放。我试图隐藏图中的轴，因为我基本上只是画了一堆矩形（棋盘）。每当我尝试隐藏轴（set(gca,'Visible','off');或axis off;）时，PDF输出似乎被剪切（我的棋盘显示中只有一个矩形）。任何想法为什么要关闭轴都搞砸了？

这是代码 - 我只是想生成一个可以扩展的棋盘

% Create a figure to get paper sizes
clear all;
clf;

% Use centimetres
set(gcf,'PaperUnits','centimeters');

% Get the paper dimensions
dims = get(gcf,'PaperSize');

inner_corner_x = 8;
inner_corner_y = 11;
margin = 2.5; % cm
dims = dims - 2*margin;

sz = round(min((dims(1)) / (inner_corner_x + 2), (dims(2)) / (inner_corner_y + 2)));

for i = 0:inner_corner_y
    for j = 0:inner_corner_x
        if mod(i + j, 2) == 0
            color = 'k';
        else
            color = 'w';
        end
        rectangle(...
            'Position', [j * sz i * sz sz sz],...
            'FaceColor', color,...
            'EdgeColor', color);
    end
end

% PROBLEM IS HERE
% Comment this line out to have ugly output, but at least all chessboard blocks show...
axis off;

set(gca,'LooseInset', get(gca,'TightInset'));
set(gcf,'PaperPositionMode','manual');
set(gcf,'PaperPosition',[margin margin dims]);

print -dpdf figure1

我最终手工编写了一个PostScript文件来生成棋盘。此特定脚本生成8.5“x 11”纸张大小的PDF，其中包含7x9个盒子。你用盒子设置盒子大小（在这种情况下是72“）。抱歉，这个答案与问题无关，但我真的无法得到我想要的这么简单的数字，所以我手动完成了并且效果很好。
