gimp color palette from image without interpolation

#Gimp color palette from image without interpolation windows#

The most recent macroĬloses all images except for the front image.įunctions for working with colors, available Images except the front image are closed. For text windows, wildcardsĪre allowed if 'pattern' ends with '.txt', '.ijm', '.js' etc. Wildcard characters '*' (matches any character sequence) and '?'įor example, close('Histo*') could be used to dispose all histogram windows.

UseĬloses windows whose title matches 'pattern', which can contain the Or 'Results' window when you meant to close the active image. This function has the advantage of not closing the 'Log' To convert one or more Unicode characters to a string.Ĭloses the active image. Index values can range from 0 to lengthOf( string). Returns the Unicode value of the character at the specified index in string. In ImageJ 1.52d or later, use changeValues(NaN,NaN,value) to replaces NaN values. For example, changeValues(0,5,5) changes all pixels less than 5 to 5,Īnd changeValues(0x0000ff,0x0000ff,0xff0000) changes all blue pixels in an RGB image to red. Refer to theĬalls a public static no-argument method in a Java class and returns a string.Ĭhanges pixels in the image or selection that have a value in the range v1- v2 Of string arguments, and returning a string. Image does not have a calibration function.Ĭalls a public static method in a Java class, passing an arbitrary number The argument must be an integer in the range 0-255 Uses the calibration function of the active image to convert a raw pixel value Returns the bit depth of the active image: 8, 16, 24 (RGB) or 32 (float). are called, otherwise, the display is refreshed only when updateDisplay() If boolean is true, the display is refreshed each time lineTo(), drawLine(),ĭrawString(), etc. Multiply the result by 180/PI to convert to degrees. Range -PI to PI, using the signs of the arguments ReturnsĬalculates the inverse tangent of y/x and returns an angle in the Returns the inverse sine (in radians) of n.Ĭalculates the inverse tangent (arctangent) of n. Set 'arm'=1 to calculate the angle from the closest vertex points left and right, or use arm>1 for more distant neighbours and smoother results. Rotates the array elements by 'd' steps (positive 'd' = rotate right).įrom a closed contour given by 'xArr', 'yArr', an array is returned holding vertex angles in degrees (straight=0, convex = positive if contour is clockwise). Returns an array that contains the first n elements of array. Sorts multiple arrays, where all the arrays adopt the sort Sorts array, which must contain all numbers or all strings. If title ends with '(row numbers)', the row number column is shown.Įxtracts a part of an array and returns it. If title ends with '(indexes)', a 0-based Index column is shown. Window, otherwise, it will be a dormant Results window If title (optional) is 'Results', the window will be the active Results ) -ĭisplays one or more arrays in a Results window Reverses (inverts) the order of the elements in array.ĭisplays the contents of array in a window.Īrray.show('title', array1, array2. Returns an array which is linearly resampled to a different length. Returns, as an array, the rank position indexes of array, starting with the index of the smallest value Returns the min, max, mean, and stdDev of array, Returns an array containing the numeric sequence 0,1,2.n-1.Īrray.getStatistics(array, min, max, mean, stdDev). Macro for an example and more documentation. Or 'flat-top', or may be omitted (meaning 'none'). WindowType can be 'none', 'Hamming', 'Hann', Returns an array holding the minima positions.Ĭalculates and returns the Fourier amplitudes of array. 'edgeMode' argument: 0=include edges, 1=exclude edges(default), 2=circular array. With v1.51n and later, there is an optional 'Tolerance' is the minimum amplitude difference Returns an array holding the peak positions Returns an array containing the elements of 'array' that contain 'filter',Įnclose the filter in parans to do regular expression matching. Returns a version of array where the element with theĪssigns the specified numeric value to each element of array. In the array that contain value have been deleted Returns a version of array where all numeric or string elements Returns a new array created by joining two or more arrays or values Returns the inverse cosine (in radians) of n.
