i have a tiff file 18000 * 18000 in Dimension and 1.20 GB in size. the tiff has 72 DPI.
I want to convert this TIFF to PNG/JPEG using 400 DPI.
I am using following code to do it
public static void ConvertTiffToJpg(String str_TiffUrl,
String str_JpgFileDestinationUrl) throws Exception {
try {
FileSeekableStream obj_FileSeekableStream = new FileSeekableStream(
new File(str_TiffUrl));
ImageDecoder obj_ImageDecoder = ImageCodec.createImageDecoder(
"tiff", obj_FileSeekableStream, null);
RenderedImage obj_RenderedImage = obj_ImageDecoder
.decodeAsRenderedImage();
JAI.create("filestore", obj_RenderedImage,
str_JpgFileDestinationUrl, "jpeg");
obj_RenderedImage = null;
obj_ImageDecoder = null;
obj_FileSeekableStream.close();
} catch (Exception ex) {
throw ex;
}
the above code perfectly works for smaller images then the specified image for example tiff image less than 5000 * 5000 in Dimension can be easily converted to JPEG / PNG [though i need to change the PNG encoder] ,
but when i try to run the same code for above mentioned file it throws an following exception
Error: One factory fails for the operation "encode"

this is because of Out of memory error.
is there any Tiled Image Writer or Fragement Image Writer available using it we will just convert a portion of an image at a time , thus we can work with normal memory available i think it might be called convert using image segmentation.
EDIT
Directly write png file using pngJ.
My purpose is to transcode SVG canvas to PNG with 400 DPI
if i use PNGTranscoder for that it throws an Out of memory exception for mentioned image size.
so i have used TiledImageTranscoder which uses following code to transcode SVG to Image.
protected void transcode(Document document, String uri,
TranscoderOutput output) throws TranscoderException {
// Sets up root, curTxf & curAoi
super.transcode(document, uri, output);
Filter f = this.root.getGraphicsNodeRable(true);
RenderContext rc = new RenderContext(curTxf, null, null);
RenderedImage img = f.createRendering(rc);
// prepare the image to be painted
int w = img.getWidth();
int h = img.getHeight();
try {
int bands = img.getSampleModel().getNumBands();
int[] off = new int[bands];
for (int i = 0; i < bands; i++)
off[i] = i;
SampleModel sm = new PixelInterleavedSampleModel(
DataBuffer.TYPE_BYTE, w, (100000 + w - 1) / w, bands, w
* bands, off);
RenderedImage rimg = new FormatRed(GraphicsUtil.wrap(img), sm);
TIFFImageEncoder enc = new TIFFImageEncoder(output
.getOutputStream(), null);
enc.encode(rimg);
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
so as you can see here the above code uses finally TIFFImageEncoder to write progressively to disk and generates 1.30 GB of TIFF file in my case.
so that's why i need to convert this generated file to PNG file.
my question here is specially for @leonbloy
can we use here PNGWriter from pngJ library to directly write the png file using 400 DPI without out of memory error , by this way we can save time as well and avoid unnecessary conversion.
or
can we Override PngImageWriter's writeImage method with pngJ library so we can achieve our goal ?
Thank You Mihir Parekh

You might try to find some TIFF-decoder and JPEG/PNG encoder that support progressive (eg one row at a time) processing. This TIFF decoder seems to support it; PNGJ supports it.
Update: To try to plug PNGJ inside PNGTrasncoder seems the way to go, but it's not so easy: you (or I, or somebody) must code the bridge between the RenderedImage format and that that PNGJ expects. (PNGJ is intentionally decoupled from java.awt.*). It might give it a look when I have some time, it seems an interesting alternative to include in Batik, the only limitation I foresee is that I don't support interlaced writing, but I don't think that's relevant.
