Hello,
I'm trying to adapt QuickTime_Writer for a stand-alone command-line
app. I want to load the images from a given directory, process them,
and build a time-lapse animation from the results. When I try this:
for(...) {
...
ImageProcessor ip = new ColorProcessor(
GOES.TIFF_WIDTH, GOES.TIFF_HEIGHT);
ip.setPixels(new ImageReader(fi).readPixels(is));
ip = ip.convertToByte(true);
ip.invert();
ip.setThreshold(thresholdLevel.LOW,
thresholdLevel.HIGH,
ij.process.ImageProcessor.RED_LUT);
stack.addSlice(np.getFileName(), ip);
}
...
writeMovie(...);
The result is a time-lapse movie without any of the processing. I ran
into similar problems trying to build time-lapse movies of ROI's and
finally found a solution with ip.fillPolygon(). However in this case,
I'm not using an ROI, I'm using the entire image. I don't understand
the process in ImageJ. If I call invert or setThreshold on an
ImageProcessor, why doesn't it reflect the changes? What do I need to
do to see those changes in the resulting movie?
Thanks,
Brian
