JAI Problem - TIFF Image to JPEG conversion

[surendra]

Hi,

I am trying to convert TIFF Image to JPEG. For some of the images I
get the following exception.

My first thought was may be the image is not correct. I can view
the Tiff image ok and I can convert to PNG as well.

Please post here if you have any info on this exception.

Regards,
Suren

tiff to png conversion

if u want to convert tiff to jpeg, check out followin code...
i wrote :stupido: this 4 tiff to png conversion ...


public static RenderedImage[] readMultiPageTiff(String *fileName*)throws IOException{
File file = new File(fileName);
SeekableStream seekableStream = new FileSeekableStream(file);
ImageDecoder decoder = ImageCodec.createImageDecoder("tiff", seekableStream, null);
int numPages = decoder.getNumPages();
RenderedImage image[]= new RenderedImage[numPages];
int count = 0;
for(int i=0;i<decoder.getNumPages();i++){
image = decoder.decodeAsRenderedImage(i);
count++;
}

String newFolderName;
String s3 = fileName;
String [] temp = null;
temp = s3.split("\\.");

int j;
j = 0;
do{
newFolderName = temp[j];
String spoonFeeding = newFolderName;
File f = new File(spoonFeeding);
f.mkdirs();
j++;
}while (j<1);

for (int i = 0; i < count; i++) {
RenderedImage page = decoder.decodeAsRenderedImage(i);
File fileObj = new File(newFolderName+"/" + (i+1) + ".png");
System.out.println("Saving " + fileObj.getCanonicalPath());
ParameterBlock parBlock = new ParameterBlock();
parBlock.addSource(page);
parBlock.add(fileObj.toString());
parBlock.add("png");
RenderedOp renderedOp = JAI.create("filestore",parBlock);
renderedOp.dispose();
}
return image;
}

jus pass the path of file to method... method read that tiff image ... create a new folder in same path names input...
and convert the tiff pages to png image...
its running fine..... :driver:

if u want d same.. thn change d code as per ur requirement ...
i use doWhile loop..
this code cause single time i passd no. of tiff images 8)
