When creating the lines, set the AlignVertexCenters property to 'on'.
dark_gray = ĭraw the underneath line a little bit thicker. % Put all the vertices together so that they can be drawn with a single % call to line().
Similarly, xv2 and yv2 are used to draw all the horizontal line segments. The coordinates of each vertical segment are separated by NaNs. Xv1 and yv1 are used to draw vertical line segments. Pay attention to the need to draw the outlines in between the pixel centers.

(Note: pixelgrid contains additional code to handle the special case where the image has only one row or column.) Construct the x- and y-vectors It can tell us the number of rows and columns in the image, as well as the spatial coordinates for the left, right, top, and bottom edges of the image. Get the spatial coordinates for drawing the outline I want to be able to call pixelgrid with no arguments and just it find everything it needs automatically.) h_im = findobj(gca, 'type', 'image') Here's a new figure with an image displayed so that I can show how each step works.
Draw the outline using two contrasting lines. Construct a single x-vector and a single y-vector that can be used to draw the entire outline. 
Instead of adding many guides with the same spaces between them, we can use the grid. Grid Designers often need to place some elements regularly, with an equal distance between them.
Get the spatial coordinates for the left, right, top, and bottom of every row and column of image pixels. To move existing guides, click on them with a Move tool and drag them to a new location. Here are the basic steps followed by my pixelgrid function on the File Exchange: That way, the outline is guaranteed to always be visible, regardless of the underlying image pixel colors. To solve this problem, I take the approach of drawing two different lines, in the same locations, with different thicknesses and contrasting colors. No matter what color we choose for the pixel outlines, there is always the possibility that some image pixels will be the same or close to that color. These can be chosen via the drop down menu and will act differently when you crop and resize your canvas. That works for the image above, but it won't work in general. You have two different grid options: Pixels and Squares. Here's some basic code that draws some gray lines on top of the lines. It would be nice to have a subtle but visible outline around each pixel. It's hard to see the individual pixels, and there's a whole row of white pixels at the bottom of the image that have disappeared into the background of the page. imshow(bw, 'InitialMagnification', 'fit') Īnd here's what it looks like when you display it using imshow. Here's the code for making the tiny image (only 4x7) shown above. But a reader asked me about it recently, so I found the code and finally submitted it. I intended to submit the code to the File Exchange, but I got sidetracked and never did that. #SWINSIAN CHANGE POSITION OF ART GRID HOW TO#
Some years ago, I blogged about how to overlay a pixel grid on an image, so that you could clearly see pixel boundaries on a zoomed-in view of the image. Get the spatial coordinates for drawing the outline.Grid-template-areas: "column-1 column-2 column-3"
