I have the following images, both 480 x 270 pixels:

AquaSilk (Zangief) vs EMP EvilRahsaan (Blanka) - capture 1

AquaSilk (Zangief) vs EMP EvilRahsaan (Gen) - capture 2

I'd like to stitch them side by side in a 960 x 270 pixel image like so (scaled down):

images side-by-side

So far, I've been using GraphicsGrid to try to achieve this:

c1 = Import["https://i.stack.imgur.com/2SRcD.png"];
c2 = Import["https://i.stack.imgur.com/zL8id.png"];
(* Frame parameter set here to emphasize next point. *)
g = GraphicsGrid[{{c1, c2}}, Frame -> True]

But there's padding between the images:

GraphicsGrid call with c1 and c2

Additionally, it's scaled incorrectly, as ImageDimensions shows:


(* Expect {960, 540} *)
{360, 180}

I can use the ImageSize parameter to explicitly set the size of the output image, but that just reproduces the above result to scale.

How can combine the images side-by-side without scaling or padding?

  • $\begingroup$ @Verbeia ImagePadding -> None actually masks the entire image with a thick white border all around, cropping the images in half with the parts along the vertical center being exposed. $\endgroup$

  • $\begingroup$ Try Grid instead of GraphicsGrid. I'm at work now so I can't really pursue this now, but GraphicsGrid enforces equal column widths, so this might be causing a problem. ImageAssemble is the neatest solution, but there are others. $\endgroup$

What you're looking for is ImageAssemble:

c1 = Import["https://i.stack.imgur.com/2SRcD.png"];
c2 = Import["https://i.stack.imgur.com/zL8id.png"];
ImageAssemble[{c1, c2}]

Mathematica graphic

It can also assemble vertically and horizontally:

ImageAssemble[{{c1, c1}, {c2, c2}}]

Mathematica graphic

  • $\begingroup$ As well as fleshing out the answer, I'm actually doing the 4x4, but displaying the NxN case is the best answer overall. $\endgroup$

Incidentally, ImageDimensions on GraphicsGrid is behaving correctly. GraphicsGrid is generating an object with head Graphics, with a default width of 360 points, and the contents scaled down to fit. ImageDimensions then creates a bitmap version of the graphic, maintaining the size on screen, and returns the dimensions for that.
