Answer : This is simple with numpy and pylab . You can set the colormap to be whatever you like, here I use spectral. from pylab import imshow, show, get_cmap from numpy import random Z = random.random((50,50)) # Test data imshow(Z, cmap=get_cmap("Spectral"), interpolation='nearest') show() Your target image looks to have a grayscale colormap with a higher pixel density than 100x100: import pylab as plt import numpy as np Z = np.random.random((500,500)) # Test data plt.imshow(Z, cmap='gray', interpolation='nearest') plt.show() If you want to create an image file (and display it elsewhere, with or without Matplotlib), you could use NumPy and Pillow as follows: import numpy, from PIL import Image imarray = numpy.random.rand(100,100,3) * 255 im = Image.fromarray(imarray.astype('uint8')).convert('RGBA') im.save('result_image.png') The idea here is to create a numeric array, convert it to a RGB image, and sa

Example 1: convert image to binary python img = cv2 . imread ( '<image path>' ) gray_img = cv2 . cvtColor ( img , cv2 . COLOR_BGR2GRAY ) Example 2: generate binay image python import numpy as np from numpy import random # Generating an image of values between 1 and 255. im_thresh = random . randint ( 1 , 256 , ( 64 , 64 ) ) # Set anything less than 255 to 0. Unnecessary if cv2 does this during threshold . # Must go before the operation below in order not to set all values to 0. im_thresh [ im_thresh < 255 ] = 0 # Set all values at indices where the array equals 255 to 1. im_thresh [ im_thresh == 255 ] = 1

Example 1: greater than in script -eq is equal to if [ "$a" -eq "$b" ] -ne is not equal to if [ "$a" -ne "$b" ] -gt is greater than if [ "$a" -gt "$b" ] -ge is greater than or equal to if [ "$a" -ge "$b" ] -lt is less than if [ "$a" -lt "$b" ] -le is less than or equal to if [ "$a" -le "$b" ] Example 2: test string equality bash strval1="Ubuntu" strval2="Windows" #Check equality two string variables if [ $strval1 == $strval2 ]; then echo "Strings are equal" else echo "Strings are not equal" fi #Check equality of a variable with a string value if [ $strval1 == "Ubuntu" ]; then echo "Linux operating system" else echo "Windows operating system" fi

Answer : Something like this would do: xargs cat <filenames.txt The xargs program reads its standard input, and for each line of input runs the cat program with the input lines as argument(s). If you really want to do this in a loop, you can: for fn in `cat filenames.txt`; do echo "the next file is $fn" cat $fn done "foreach" is not the name for bash. It is simply "for". You can do things in one line only like: for fn in `cat filenames.txt`; do cat "$fn"; done Reference: http://www.cyberciti.biz/faq/linux-unix-bash-for-loop-one-line-command/ Here is a while loop: while read filename do echo "Printing: $filename" cat "$filename" done < filenames.txt

Answer : If you are using 2.0.0-beta2, you can use tooltip callback and return array of strings there. tooltips: { mode: 'single', callbacks: { afterBody: function(data) { var multistringText = ['first string']; // do some stuff multistringText.push('another string'); return multistringText; } } } Actually all tool-tip callbacks support multiple lines of text, and you can use label callback as usual. It renders data label as tool-tip text by default. Quoted from documentation: All functions must return either a string or an array of strings. Arrays of strings are treated as multiple lines of text. Example code: tooltips: { callbacks: { label: (tooltipItem, data) => { if (tooltipItem.index % 2) return ['Item 1', 'Item 2', 'Item 3']; else return 'Single line'; } } } You can use

Answer : The API documentation is quite clear on this. First create a new Location instance: Location loc = new Location("dummyprovider"); And then use the setter methods to set the location parameters you need, e.g.: loc.setLatitude(20.3); loc.setLongitude(52.6); Location object = new Location("service Provider"); it will create an object of Type Location that contains the initial Latitude and Longitude at location '0' to get the initial values use double lat = object.getLatitude(); double lng = object.getLongitude(); In Kotlin using LocationManager class you can pass the required location provider like: val location = Location(LocationManager.NETWORK_PROVIDER) // OR GPS_PROVIDER based on the requirement location.latitude = 42.125 location.longitude = 55.123
