ImageProcessingTests

public ImageProcessingTests()

Method Details

main

public static void main(String[] args)

Method to test the imageprocessing tasks in isolation.

Parameters:

args - Args.

createB64ImageStringFromImage

public static void createB64ImageStringFromImage(String path)
                                          throws IOException

Utility method to create new test data from images, will be saved to the testimage folder.

Parameters:

path - Path to the image to use.

Throws:

IOException - If the process fails to find, load or write to a file.

testGrayscaling

public static BufferedImage testGrayscaling(BufferedImage image)

Testing the grayscaling of images, not much possible automated, just to make sure its not broken.

Parameters:

image - the image to be grayscaled.

Returns:

the inputimage in grayscale.

testThresholdingImage

public static BufferedImage testThresholdingImage(BufferedImage image,
 int threshold)

Testing turning an image into black and white, no real assertion possible thus testing if it breaks.

Parameters:

image - the image to be turned into black and white.

threshold - the color value will be used to separate into black and white.

Returns:

the Image in black and white.

testRescalingOfImage

public static BufferedImage testRescalingOfImage(BufferedImage image,
 int height,
 int width)

Tests the rescaling function of the imageprocessing class. Only testing for exception as the result cannot be evalutated automaticaly.

Parameters:

image - the image to be resacled.

height - the target height of the new image.

width - the target width of the new image.

Returns:

the image with its new dimensions.
