This is a very bare-bones example that demonstrates how to put an SWT Browser view into a Swing JFrame. Note that you need to download the SWT toolkit and put it in your classpath of your Java project for this to work.

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextField;
import org.eclipse.swt.SWT;
import org.eclipse.swt.awt.SWT_AWT;

import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

Basic Fahrenheit to Celsius converter with Swing. Try converting Degrees, Minutes, Seconds coordinates to Decimal coordinates.
public class CelsiusConverterGUI extends javax.swing.JFrame {
/**
* Creates new form CelsiusConverterGUI
*/
public CelsiusConverterGUI() {
initComponents();
}

Putting the ! there actually makes sense with the wording in the logic, because the else statement has the var googleRowNumber, and the row number is indeed a google row, not a TMS row.
if (!isTMSstructure) {
imgName = imageFile.getName();
} else {
int zoom = Integer.parseInt(resultZoomDirectory.getName());
int googleRowNumber = Integer.parseInt(FileUtils.getFileNameWithoutExtension(imageFile.getName()));
imgName = String.valueOf(
(int) (Math.pow(2, zoom) - 1 - googleRowNumber)) + "." + FileUtils.getFileExtension(imageFile.getName());
}

Sums a bunch of binary masks together so you can have classification groups that show how many images in our set are cloudless.

arcpy.CheckOutExtension('Spatial')
arcpy.env.overwriteOutput = True
cwd = os.getcwd()
inputPath = cwd + "\\intermediate\\"
outputPath = cwd + "\\output\\"

This script just composites bands 4,3,2 into an RGB composite tiff for all of the outputs of holy cloud imagery.

This script averages together all of the RGB values from each image. Because the clouded pixels are set to 0, Those values are ignored in the average. We divide the sum of values by another raster that is the sum of valid pixels based on BQA classification.
