getframe

Capture figure or axes as movie frame.

Syntax

• F = getframe
• F = getframe(ax)
• F = getframe(fig)

Input argument

• ax - axes object: Axes to capture.
• fig - figure object: Figure to capture.

Output argument

• F - struct: Movie frame.

Description

F = getframe captures the current axes as displayed on the screen as a movie frame. F is a structure containing the image data. The capture preserves the on-screen size of the axes but does not include tick labels or any content outside the axes boundaries.

F = getframe(ax) captures the specified axes ax instead of the current axes.

F = getframe(fig) captures the entire figure window specified by fig, including the axes title, labels, and tick marks. However, the captured frame does not include the figure’s menu or toolbars.

Examples

f = figure();
surf(peaks);
F = getframe(f);
figure('Color',[0.5 0.5 0.5]);
imshow(F.cdata)

f = figure();
ax1 = subplot(2,1,1);
surf(peaks);
ax2 = subplot(2,1,2);
plot(rand(30))
F1 = getframe(ax1);
F2 = getframe(ax2);
figure('Color',[0.5 0.5 0.5]);
imshow(F1.cdata)
figure('Color',[0.5 0.5 0.5]);
imshow(F2.cdata)
