@Override
public void process(FilterContext env) {
    Frame output = env.getFrameManager().newFrame(mOutputFormat);
    output.setObjectValue(mString);

}

Example 32 with Frame

the class InputStreamSource method process.

@Override
public void process(FilterContext context) {
    int fileSize = 0;
    ByteBuffer byteBuffer = null;
    // Read the file
    try {
        ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = mInputStream.read(buffer)) > 0) {
            byteStream.write(buffer, 0, bytesRead);
            fileSize += bytesRead;
        }
        byteBuffer = ByteBuffer.wrap(byteStream.toByteArray());
    } catch (IOException exception) {
        throw new RuntimeException("InputStreamSource: Could not read stream: " + exception.getMessage() + "!");
    }
    // Put it into a frame
    mOutputFormat.setDimensions(fileSize);
    Frame output = context.getFrameManager().newFrame(mOutputFormat);
    output.setData(byteBuffer);
    // Push output
    pushOutput("data", output);
    // Release pushed frame
    output.release();
    // Close output port as we are done here
    closeOutputPort("data");
}

Example 33 with Frame

use of android.filterfw.core.Frame in project platform_frameworks_base by android.

the class OutputStreamTarget method process.

@Override
public void process(FilterContext context) {
    Frame input = pullInput("data");
    ByteBuffer data;
    if (input.getFormat().getObjectClass() == String.class) {
        String stringVal = (String) input.getObjectValue();
        data = ByteBuffer.wrap(stringVal.getBytes());
    } else {
        data = input.getData();
    }
    try {
        mOutputStream.write(data.array(), 0, data.limit());
        mOutputStream.flush();
    } catch (IOException exception) {
        throw new RuntimeException("OutputStreamTarget: Could not write to stream: " + exception.getMessage() + "!");
    }
}

Example 34 with Frame

use of android.filterfw.core.Frame in project platform_frameworks_base by android.

the class RetargetFilter method process.

@Override
public void process(FilterContext context) {
    // Get input frame
    Frame input = pullInput("frame");
    // Create output frame
    Frame output = context.getFrameManager().duplicateFrameToTarget(input, mTarget);
    // Push output
    pushOutput("frame", output);
    // Release pushed frame
    output.release();
}

Example 35 with Frame

use of android.filterfw.core.Frame in project platform_frameworks_base by android.

the class DocumentaryFilter method process.

@Override
public void process(FilterContext context) {
    // Get input frame
    Frame input = pullInput("image");
    FrameFormat inputFormat = input.getFormat();
    // Create program if not created already
    if (mProgram == null || inputFormat.getTarget() != mTarget) {
        initProgram(context, inputFormat.getTarget());
    }
    // Check if the frame size has changed
    if (inputFormat.getWidth() != mWidth || inputFormat.getHeight() != mHeight) {
        mWidth = inputFormat.getWidth();
        mHeight = inputFormat.getHeight();
        initParameters();
    }
    // Create output frame
    Frame output = context.getFrameManager().newFrame(inputFormat);
    // Process
    mProgram.process(input, output);
    // Push output
    pushOutput("image", output);
    // Release pushed frame
    output.release();
