‍4 Matlab代码

主函数部分代码：

function X = getframeWithDecorations(f, withDecorations, doDrawnow)
% GETFRAMEWITHDECORATIONS(f) Capture the whole figure including window decorations.
% GETFRAMEWITHDECORATIONS(f, withDecorations) Capture the whole figure, including decorations if the flag is true

    if nargin < 2
        withDecorations = true;
    end

    if nargin < 3
       doDrawnow = true;
    end

    % some clients may have done preemptive drawnow on their own
    % avoiding calls here may save a little time 
    if doDrawnow
       drawnow
       drawnow
    end

    if ~isgraphics(f, 'figure')
        error(message('MATLAB:capturescreen:FigureWindowRequired'));
    end

    if matlab.ui.internal.isUIFigure(f)
        cdata = getWebFigureWithDecorations(f, withDecorations);
    else
        cdata = getJavaFrameWithDecorations(f, withDecorations);
    end

    % Need to initialize fields in this order
    X.cdata = cdata;
    X.colormap = [];
end
