ginput to select RGB values of image to hold Learn more about image processing MATLAB. Unfortunately, this crosshair is black, and in the axes where I need this function the background is, usually, Hello. It is not possible to change the pointer color. :) thank you I am using a ginput function in Matlab to set the limit of a line with two points using ginput(2). For example see my attached code where I changed the [0,0,0] I am trying to change the color of the cursor when using the "ginput" function and am unable to do so. See the ColorSpec reference page for more information on specifying color. Unfortunately, this crosshair is black, and in the axes where I need this function the background is, usually, Hello, I need to use ginput. Pointers are handled by the operating system, and are one-bit (black and white) with a 1 bit mask (transparent or not). For example see my attached code where I changed the [0,0,0] to [1,1,1] (white). [x,y] = ginput(n) enables you to select n points from the current Axes and returns the x - and y -coordinates in the column vectors x and y, respectively. Use a local copy of Mathworks' original function ginput. Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. Simple Question: is it possible to Change the Cursor appearance in ginput ? Explanation: If you use the ginput command, you will get a Crosshair as Cursor. You need to modify the built-in ginput () function since they forgot to add this incredibly obvious and needed option of color. For example see my attached code where I changed the [0,0,0] Since ginput is not editable, I copied all content into a function, and changed the call to ginput to the new function instead. . :) thank you How do I define a color?.

Learn more about color, colour, selecting, color segmentation Image Processing Toolbox I am trying to change the color of the cursor when using the "ginput" function and am unable to do so. From the colour segmentation tutorial they used the ginput command so that I can physically pick the colour on 'Color' : A three-element RGB vector, or one of the MATLAB predefined names, specifying the line color. Is it possible to get You need to modify the built-in ginput () function since they forgot to add this incredibly obvious and needed option of color. Here’s the same image, but Hello, I need to use ginput. Unfortunately, this crosshair is black, and in the axes where I need this function the background is, usually, The Figure must have focus before ginput receives input. 通常，Matlab ginput 函数的十字线颜色默认为黑色。但是有些图背景为黑色，这时坐标提取难较分辨，精度低。为了解决这个问题，可通过修改ginput函数实现自定义十字线颜色，提高坐标 Simple Question: is it possible to Change the Cursor appearance in ginput ? Explanation: If you use the ginput command, you will get a Crosshair as Cursor. Hello. ?? cause the color is transparent, sometimes i can't see where is my cursor. ^^ is possible to change the cursor's color of "ginput" when i implement it. It "raises raises crosshair in the axes" - which is fine. Adapt this copy to take two arguments: "Number of ginput points" and "pointersymbol". Basically, I am trying to end up with just one of the colours and count them. You need to modify the built-in ginput () function since they forgot to add this incredibly obvious and needed option of color. The ability to change the color of the cursor to something other than black or white when using the "ginput" function is not available in MATLAB. Hello All, Is there a way to display a counter for the number or ginput mouse clicks on the image as you are making the inputs? If that is not possible, can you alternate ginput marker colors? Jiro wrote a new function based on MATLAB's ginput that makes the color and thickness of the cursor fully customizable. A cross-hair appears, but it's not connected in the middle. Hello, I need to use ginput. Below is the modification to ginput. m which has precedence in your Matlab path.
