plot(cos(linspace(0, 7, 1000)));
set(gcf, 'Position', [100 100 150 150]);
set(gca,'xtick',[],'xticklabel',[]);
set(gca,'ytick',[],'yticklabel',[]);
set(gca, 'Color', 'none'); % Sets axes background
axis off;
export_fig test.png -transparent
效果如下:终于得到了透明的图像
plot(cos(linspace(0, 7, 1000)));
set(gcf, 'Position', [100 100 150 150]);
set(gca,'xtick',[],'xticklabel',[]);
set(gca,'ytick',[],'yticklabel',[]);
set(gca, 'Color', 'none'); % Sets axes background
axis off;
export_fig test.png -transparent -r300; % 调整图像的清晰度
这个是可以的
plot(dff(14,:));
set(gcf, 'Position', [100 100 150 150]);
set(gca,'xtick',[],'xticklabel',[]);
set(gca,'ytick',[],'yticklabel',[]);
set(gca, 'Color', 'none'); % Sets axes background
axis off;
export_fig('test2.png', '-transparent','-r300');
% export_fig test.png -transparent -r300;
一定要注意,要把
axis off;
加上去,这样就可以把四个边界也给消除掉!
