Open and add 4 JPEGs into a 2x2 window

Question

Hi,

How do I write a script to open 4 jpegs in JMP and then place them in a 2x2 window? I would like to specify the size of the window to be a certain size. Then I would like to save the window into a jpeg.

Any help is appriciated! Thanks!

I would go with the Lineup box like Jim did show as I think it is the simplest option. One other option (more complicated) is to use Graph Box and add images to it

Names Default To Here(1);

image1 = New Image("$SAMPLE_IMAGES/windmap.png");
image2 = New Image("$SAMPLE_IMAGES/black rhino footprint.jpg");
image3 = New Image("$SAMPLE_IMAGES/tile.jpg");
image4 = New Image("$SAMPLE_IMAGES/pi.gif");

nw = New Window("View Image",
	gb = Graph Box(
		FrameSize(500, 500),
		X Scale(0, 100),
		Y Scale(0, 100),
		SuppressAxes(1)
	)
);

fb = nw[FrameBox(1)];

fb << Add Image(image(image1), bounds(top(0), Left(0), bottom(50), Right(50)));
fb << Add Image(image(image2), bounds(top(0), Left(50), bottom(50), Right(100)));
fb << Add Image(image(image3), bounds(top(100), Left(0), bottom(50), Right(50)));
fb << Add Image(image(image4), bounds(top(100), Left(50), bottom(50), Right(100)));

img = fb << get picture;
img << save image("$TEMP/pic.png", "png");
nw << close window;

At least one more technique can be found from this post Merging/stitching images

Here is a simple example of one way to handle the question

Names Default To Here( 1 );

image1 = New Image( "$SAMPLE_IMAGES/windmap.png" );
image2 = New Image( "$SAMPLE_IMAGES/black rhino footprint.jpg" );
image3 = New Image( "$SAMPLE_IMAGES/tile.jpg" );
image4 = New Image( "$SAMPLE_IMAGES/pi.gif" );

nw = New Window( "Pictures",
	Outline Box( "The Pictures",
		Lineup Box( N Col( 2 ), image1, image2, image3, image4 )
	)
);

theWholePicture = nw[Outline Box( 1 )] << get picture;

theWholePicture << save image( "$TEMP/myPicture.jpg,", "jpg" );

nw << close window;

theSavedImage = New Image( "$TEMP/myPicture.jpg," );

theNW = New Window( "Final Picture", theSavedImage );

You can set the images sizes by using

img << Set Size( {600, 600} );

See the Scripting Index for the messages that can be used with New Image
