explain

print(filename,formattype) Use the specified file format to save the current drawing window to a file , for example print('BarPlot','-dpng'). If the file does not include an extension , be print The applicable extension will be appended .

print(filename,formattype,formatoptions) Specify additional options available for some formats .print Output the current window to the default printer .

print(printer) Specify the printer . Specify the printer as a character vector or string , It includes -P Printer name at the beginning , for example '-Pmy printer'. The printer must be set up on your system .

print(driver) Specify the driver . If you want to ensure that the printed output is black and white or color , Use this option .

print('-clipboard',clipboardformat) Use clipboardformat Copy the current drawing window to the clipboard in the specified format . You can paste the copied window into other applications .

print(resize,___) Maximize the picture window to fill the page . take resize Designated as '-bestfit' The aspect ratio of the drawing window can be preserved , Designated as '-fillpage' The aspect ratio is ignored . These options can only be saved in page format （PDF and PS） Or send it to the printer for printing . This option can be used with any input parameter in the previous syntax .

print(resolution,___) Use the specified resolution . Specify the resolution as a character vector or string , It includes -r Integer value at the beginning , for example '-r200'. This option can be used with any input parameter in the previous syntax .

print(renderer,___) Use the specified renderer . The renderer can be specified as '-vector' or '-image'.

print('-noui',___) Do not include user interface controls in saved or printed output （ Such as ordinary buttons and sliders ）. It does not exclude user interface objects that can contain coordinate areas , for example uitab or uipanel.

print(fig,___) Save or print fig The specified window or window Simulink Module diagram .

cdata = print('-RGBImage'); Return to the current window RGB Image data . The difference between this option and screenshot is that all printing functions can be applied to output . You can also use this syntax to specify resolution、renderer、'-noui' and fig Options . however , Cannot specify Simulink Module diagram .

Example

Print a copy of the chart window paper

         Create a bar chart and output it to the system default printer . If you do not specify the drawing window to print , be print Use the current drawing window .

bar(1:10)
print

Copy the window to the clipboard

         Create a drawing and copy it to the system clipboard .

plot(1:10)
print('-clipboard','-dmeta')

         You can paste the copied drawing into other applications .

Save the picture window as an image file

         Create a drawing and save it as PNG image file .

bar(1:10)
print('BarPlot','-dpng')

        print Save the drawing as BarPlot.png.

Save the drawing window as a vector graphics file

         Create a drawing and save it as encapsulated PostScript  file .

bar(1:10)
print('BarPlot','-depsc')

        print Save the drawing as BarPlot.eps.

towards EPS File to add TIFF preview

         Save the current drawing window as encapsulated PostScript File and add TIFF preview .

surf(peaks)
print('SurfacePlot','-depsc','-tiff')

Specify the drawing window to save

         By passing the object variable of a specific drawing window to print To save the drawing window .

fig = figure;
plot(1:10)
print(fig,'MySavedPlot','-dpng')

         perhaps , To use its Number The value of the attribute refers to the window , This value is the integer value displayed in the title bar of the drawing window . for example , Save the drawing window and display it in the title bar Figure 2. Add -f.

figure(2);
plot(1:10)
print('-f2','MySavedPlot','-dpng')

Save the picture window in screen size and resolution

         Save the surface diagram to PNG In file . Put the picture window PaperPositionMode Property is set to 'auto' To save it as the size displayed on the screen . Use '-r0' It can be saved according to the screen resolution .

surf(peaks)
set(gcf,'PaperPositionMode','auto')
print('PeaksSurface','-dpng','-r0')

Save the picture window that fills the page

Use '-fillpage' Option to save the picture window that fills the page .

bar([1 10 7 8 2 2 9 3 6])
print('FillPageFigure','-dpdf','-fillpage')

Save the drawing window without saving UIControl

         Create a diagram window , It contains common buttons for clearing the coordinate area . Save the drawing window to JPEG File without saving ordinary buttons .

surf(peaks)
uicontrol('Style','pushbutton','String','Clear',...
    'Position',[20 20 50 20],'Callback','cla');
print('SurfacePlot','-djpeg','-noui')

Return to the RGB Image data

         Return to the RGB Image data .

surf(peaks)
cdata = print('-RGBImage');

         Use imshow Display image data at full resolution .

imshow(cdata)

Create high resolution movie frames

         Create a surface graph . Return to the RGB Image data , And specify the image resolution . then , Convert image data into movie frames F.

surf(peaks)
cdata = print('-RGBImage','-r120');
F = im2frame(cdata);

filename - file name

         file name , Specified as a character vector or string , It contains the required file name and path . Maximum length of file name （ Including paths ） Specific to the operating system and file format . Usually , The file name should not exceed 126 Characters , If the path is included , Should not exceed 128 Characters .

formattype - File format

File format , Specify as one of the options in these tables . Bitmap image is a picture window expressed in pixels . The size of the generated file depends on the window 、 Format and system resolution .Web Bitmaps are widely used in browsers and other applications that display graphics . however , They do not support transparency or scaling well , And you can't modify graphic objects in other graphic applications , Such as lines and text .

Options	The bitmap format	Corresponding file extension
'-djpeg'	JPEG 24 position	.jpg
'-dpng'	PNG 24 position	.png
'-dtiff'	TIFF 24 position （ Compress ）	.tif
'-dtiffn'	TIFF 24 position （ non-compressed ）	.tif
'-dmeta'	Enhanced metafile （ Limited to Windows）	.emf
'-dbmpmono'	BMP monochrome	.bmp
'-dbmp'	BMP 24 position	.bmp
'-dbmp16m'	BMP 24 position	.bmp
'-dbmp256'	BMP 8 position （256 color , Use a fixed color map ）	.bmp

'-dpgmraw'	PGM（ Original format ）	.pgm
'-dppm'	PPM（ Normal format ）	.ppm
'-dppmraw'	PPM（ Original format ）	.ppm

Vector graphics file

         The vector graphics file stores commands for redrawing the drawing window . This format type is suitable for scaling , But it may lead to large files . in addition , It may produce objects with wrong three-dimensional arrangement in some cases . Some applications support extensive editing of vector graphics formats . however , Some applications do not support editing other than resizing graphics . Usually , Try to MATLAB Make all necessary changes to the drawing window .

         If you set the Renderer attribute , be print Use this renderer when generating output . otherwise ,print Will choose the appropriate renderer . Usually ,print The generated vector graphics file scales well when resizing . For some complex picture windows , The file may contain embedded bitmap images . These bitmap images do not scale well , It may limit the extent to which these images can be edited in other applications . Make sure print Use the vector graphics renderer , Please put '-vector' Designated as print Function's input parameters .

         If you want the output to be transparent , Then use metafile 、PDF or SVG Format to create vector graphics file . If you use PS or EPS Format , Only the picture window and coordinate area background support transparency . Bitmap images do not support transparency , But it will be close to the screen display , Present transparent effect .
