John Hunter Excellence in Plotting Contest submissions are open! Entries are due June 1, The input may either be actual RGB A data, or 2D scalar data, which will be rendered as a pseudocolor image. The Colormap instance or registered colormap name used to map scalar data to colors. This parameter is ignored for RGB A data. Defaults to rcParams["image.

The Normalize instance used to scale scalar data to the [0, 1] range before mapping to colors using cmap. By default, a linear scaling mapping the lowest value to 0 and the highest to 1 is used. Controls the aspect ratio of the axes. The aspect is of particular relevance for images since it may distort the image, i.

This parameter is a shortcut for explicitly calling Axes. See there for further details. If not given, use rcParams["image. The interpolation method used. If NonercParams["image.

Supported values are 'none', 'antialiased', 'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36', 'hanning', 'hamming', 'hermite', 'kaiser', 'quadric', 'catrom', 'gaussian', 'bessel', 'mitchell', 'sinc', 'lanczos'. If interpolation is 'none', then no interpolation is performed on the Agg, ps, pdf and svg backends. Other backends will fall back to 'nearest'. Note that most SVG renders perform interpolation at rendering and that the default interpolation method they implement may differ.

If interpolation is the default 'antialiased', then 'nearest' interpolation is used if the image is upsampled by more than a factor of three i. If the upsampling rate is smaller than 3, or the image is downsampled, then 'hanning' interpolation is used to act as an anti-aliasing filter, unless the image happens to be upsampled by exactly a factor of two or one. See Interpolations for imshow for an overview of the supported interpolation methods, and Image antialiasing for a discussion of image antialiasing.

Some interpolation methods require an additional radius parameter, which can be set by filterrad. Additionally, the antigrain image resize filter is controlled by the parameter filternorm. The alpha blending value, between 0 transparent and 1 opaque.

If alpha is an array, the alpha blending values are applied pixel by pixel, and alpha must have the same shape as X. When using scalar data and no explicit normvmin and vmax define the data range that the colormap covers. By default, the colormap covers the complete value range of the supplied data. Place the [0, 0] index of the array in the upper left or lower left corner of the axes.

The convention 'upper' is typically used for matrices and images. If not given, rcParams["image. See the origin and extent in imshow tutorial for examples and a more detailed description.Sign in to comment.

I am using he imread function to load. I am getting the following error. I ended up with a x pixel image. Any comment on the above would be appreciated.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Right now when we are showing, it is exactly fitted to the image window size. However, I want to show the image in its original size. When the image is of larger size, a scroll bar should appear in the image window. This would allow the user to view the image in its original size.

If you don't want the image appearing in a new window, but instead want to adjust its size in a window of your own, it will be more difficult. To adjust the size of the image, which I assume you've displayed on a set of axes using the IMAGE command, you will have to adjust a number of axes properties for the axes containing the image.

The following are the properties you will likely end up modifying:. After getting the size and scaling of the image to display the way you want, parts of the image could be outside the figure window area.

Unfortunately, horizontal and vertical sliders will not be automatically added. You will have to write the callback functions for the slider controls such that they move the axes around in the window. If you choose to venture down the above path, here are a few links to GUI design tutorials that may help you: a slider tutorial on blinkdaggera blog post by Doug Hulland a video from Doug on GUIDE basics.

Matlab slider has a problem that it fires callback only on MouseUp and not on MouseMove, so pure matlab implementation would always feels strange. Better way - go for Java in Matlab. So you do not have to re-implement whole scroll logics. With Matlab javacomponent function you can put it inside matlab window.

There are tons of examples on the web on how to get image into scroll pane, just browse for JScrollPane image. You can use Java classes inside matlab with usual Matlab syntax no need for new keyword, ecc. Forum post link. Funny, nobody here has mentioned truesize yet:.

If you do not specify a figure, truesize adjusts the display size of the current figure. Once all of that are set according to the image size even using MATLAB's image function one could generate display of an image.

Fatih Temiz on 23 Nov Vote 0. Edited: Robert U on 24 Nov Although a lot of similar questions had been asked, I couldn't solve the problem that setting sizes of subfigures in a figure? Associated part of my code is here:. While they are matrices of X I have no problem.Updated 29 Oct To adjust window and level values keep the mouse right button pressed, and drag the mouse up and down for level adjustment or right and left for window adjustment.

Window and level adjustment control works only for grayscale images. The time interval value can also be adjusted default time interval is ms. Note: The sensitivity of mouse-based window and level adjustment is set based on the user-defined display intensity range; the wider the range, the more sensitivity to mouse drag. Maysam Shahedi Retrieved April 18, Hi Adam, My suggestion is to modify imshow3D code and make your own version of imshow3D.

You can add the plot command within the code. Hope it helps. I wish to plot points on specific slices. Each points have an X,Y, and Z component Z being the slice number. I have tried using the code below. Hi, You can send me your questions about the function via the email address I have provided mshahedi gmail. Thank you! Hello, It's my first time using Matlab and I'm having a difficult time trying to understand the function you wrote regarding imshow3D.

Do you have any advice for me how to get to the bottom of it? Thank you, Sigal. My apology if the name was misleading to you. I called it imshow3D because, as I mentioned in the subtitle, it displays "3D images" slice-by-slice. I also wanted to make it similar to imshow command of Matlab. I don't understand why you call it 3d show while it is showing 2d images and show slice by slice?

The accepted data type for imwrite is unsigned integer e. Try imwrite im2uint16 image :,:,'raw3D. For saving the image, if you use the figure menu bar you will get a snapshot of the whole GUI and you need to crop it.

To avoid that you can try saving your image using "imwrite" command. It does not matter what is the image file format. Hi Matthew, Thank you for your interest in imshow3D. You need to input your image as a 3D matrix e. Img as follows:. I am new to Matlab and I'm having difficulty using this function. I keep getting 'undefined function or variable 'Img''.

By the way, in the next update in few days an option will be added to the function for calling the function with a specific display intensity range, similar to what we have for "imshow" function.
