Png2PdfGUI - A graphical user interface to png2pdf


Overview

The Java application Png2PdfGUI provides a graphical user interface to the png2pdf program. To convert PNG files to PDF you have to perform the following tasks:

These main tasks can be performed using buttons in the button bar or using menu entries.


Requirements

To use the Png2PdfGUI you must have the png2pdf program installed. Normally this conditions is fullfilled because Png2PdfGUI and png2pdf are in the same package, so they are installed at the same time.

A Java run-time environment (Java 5) must be installed. Previous versions are not sufficient to run Png2PdfGUI.


Starting the program

On Windows systems

In a prompt box run

java.exe -cp c:\programs\krause\lib\png2pdf.jar;c:\programs\krause\lib\dklibsj.jar Png2PdfGUI
You possibly need to replace c:\programs\krause by another directory, depending on your decisions during installation process.

Once you have verified the program starts correctly you can create shortcuts either on the desktop or in the start menu. For shortcuts you should use javaw.exe instead of java.exe.

On Unix/Linux systems

Run

java -c /usr/local/lib/png2pdf.jar:/usr/local/lib/dklibsj.jar Png2PdfGUI
to start the program.


Program appearance at start

When running the program for the first time the main window looks like this:
 


Choosing a directory

Use either the "Choose directory" button or the menu entry "Png2pdf / Directory" to choose the directory.
 

 
The directory chooser dialog appears.
 

 
Navigate to the directory containing your PNG files and confirm the selection.
The new working directory is shown in the main window.
 

You can also attempt to use drag'n'drop to drag a directory from Windows explorer or Nautilus into the Png2PdfGUI main window. For other Unix/Linux desktops it is not known whether drag'n'drop works, just try it.


Set png2pdf options

Use either the "Set options" button in the button bar or the "Png2pdf / Options" menu entry to set conversion options.
 

 

 
In the "Png2pdf Options" dialog you have the following choices:


Running a conversion

Use the "Run png2pdf" button from the button bar or the "Png2pdf / Run" menu entry to start a conversion.
 

 
While the conversion is running the status text color changes to red and the text changes to "Running". If you decided to see file names the text changes to "Processing ...".
 

 
After all conversions are done the color changes back to green and the text changes back to "Ready".


Exiting the program

Use either the "Exit the GUI" button in the button bar or the "Png2pdf / Exit" menu entry to exit the program.
