#Matlab color2gray how to
See the CData and FaceVertexCData property descriptions for information on how to specify color. The CData and FaceVertexCData properties accept color data as indexed or true color (RGB) values. FaceVertexCData - use when specifying vertices and connection matrix ( Vertices and Faces).CData - use when specifying x-, y-, and z-coordinates ( XData, YData, ZData).
#Matlab color2gray Patch
There are two patch properties that specify color: You can specify properties as property name/property value pairs, structure arrays, and cell arrays (see the set and get reference pages for examples of how to specify these data types). In that case, it is better to break up the face into smaller polygons. However, if the edges of an individual patch face intersect themselves, the resulting face may or may not be completely filled. The data can define concave or intersecting polygons. If the coordinate data does not define closed polygons, patch closes the polygons. It simply adds the patch object to the current axes. Unlike high-level area creation functions, such as fill or area, patch does not check the settings of the figure and axes NextPlot properties.
Returns the handle of the patch object it creates. See the "Examples" section for more information. This form also allows you to specify the patch using the Faces and Vertices properties instead of x-, y-, and z-coordinates. This form enables you to omit the color specification because MATLAB uses the default face color and edge color, unless you explicitly assign a value to the FaceColor and EdgeColor properties. Specifies all properties using property name/property value pairs. These fields correspond to the Vertices, Faces, and FaceVertexCData patch properties.įollows the X, Y, ( Z), and C arguments with property name/property value pairs to specify additional patch properties. If C is a 1-by-3 vector, it is assumed to be an RGB triplet, specifying a color directly.Ĭreates a patch in three-dimensional coordinates.Ĭreates a patch using structure FV, which contains the fields vertices, faces, and optionally facevertecdata. It can be a single ColorSpec, one color per face, or one color per vertex (see "Remarks"). If X and Y are matrices, MATLAB draws one polygon per column. The elements of X and Y specify the vertices of a polygon. See the Creating 3-D Models with Patches for more information on using patch objects.Īdds the filled two-dimensional patch to the current axes. You can specify the coloring and lighting of the patch. A patch object is one or more polygons defined by the coordinates of its vertices. Patch is the low-level graphics function for creating patch graphics objects. Patch(' PropertyName',PropertyValue.)
