Constructor Detail

ImageToZxSpec

public ImageToZxSpec()

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Create a single thread for the rendering and inits the UI

Parameters:

args -

Throws:

java.lang.Exception

createUserInterface

public static void createUserInterface()

Create the natty UI/preview window. Very monolithic but I don't intend to change this much, and if I do I'll be sure to rewrite 8P

isSupported

static boolean isSupported(java.io.File f)

processPreview

static void processPreview()

Method to begin the (multi dither, not WIP) preview which submits work to the work engine and controls the UI settings and validates the content being loaded.

startPreviewWaiter

private static void startPreviewWaiter(java.util.List<java.util.concurrent.Future<WorkContainer>> futures)

A "waiter" which waits for the work engine (the WorkDispatcher) to return a result so it can be displayed in the dither preview dialog when it is ready. The list of futures contains the work dispatcher's work in progress Future tasks.

Parameters:

futures -

processFiles

public static void processFiles()

Method to begin the WIP preview which submits work to the work engine and controls the UI settings and validates the content being loaded. In particular if a video is found in the input only this file is processed.

processVideo

private static void processVideo(java.io.File f)
                          throws java.lang.InterruptedException,
                                 javax.media.NoPlayerException,
                                 java.io.IOException,
                                 java.util.concurrent.ExecutionException,
                                 java.lang.InstantiationException,
                                 java.lang.IllegalAccessException,
                                 java.lang.ClassNotFoundException

Inner core method for the process files method that specifically deals with a video file. The file is converted to a number of images and this work is put into the work engine as per the usual procedure for images. A waiter thread is initialised to pick the completed work up and as the images are loaded in order the future tasks' results remain correctly ordered when they are collected.

Parameters:

f -

Throws:

java.lang.InterruptedException

javax.media.NoPlayerException

java.io.IOException

java.util.concurrent.ExecutionException

java.lang.InstantiationException

java.lang.IllegalAccessException

java.lang.ClassNotFoundException

                                       java.util.concurrent.ExecutionException

Inner core method for the process files method that specifically deals with a single files. The files are loaded as images and these are put into the work engine for processing. A waiter thread is initialised to pick the completed work up and as the images are loaded in order the future tasks' results remain correctly ordered when they are collected.

Throws:

java.lang.InterruptedException

javax.media.NoPlayerException

java.io.IOException

java.util.concurrent.ExecutionException

startWaiter

private static void startWaiter(java.util.List<java.util.concurrent.Future<WorkContainer>> futures,
                                java.lang.String videoName)

A "waiter" which waits for the work engine (the WorkDispatcher) to return a result so it can be displayed in the WIP preview when it is ready. The list of futures contains the work dispatcher's work in progress Future tasks. When the results are returned as buffered images or scrs the relevant scr, tap, png, jpg etc is created. In the case of video the videoName is used for the file name base.

Parameters:

futures -

startFpsCalculator

private static void startFpsCalculator()

Sets a status or error message above the convert button

Parameters:

message -

enableInput

public static void enableInput()

Reset's the UI state to enable input
