JDeli is able to convert SGI to TIFF image files.
JDeli can do this in ONE step with the convert method. You can also do this by reading an SGI image and then writing the image as TIFF, which is useful if you want to process the image in some way.
Convert any images to TIFF from Command Line or another language
java -jar jdeli.jar --convert tif "inputFileOrDir" "outputDir"
Single step method to convert from SGI into TIFF image file in Java
JDeli.convert(File inFile, File outFile);
JDeli.convert(InputStream inFile, OutputStream outfile, String format);
byte outputData = JDeli.convert(byte inputData, String format);
Depending on the image formats being converted (ie set compression level in Tiff files), JDeli also provides overloaded methods. These can be used to supply conversion options for more control over the conversion process.
Read / Write methods for converting from SGI into TIFF image file in Java
1. Read SGI image into Java
BufferedImage image = JDeli.read(imageFile);
SgiDecoder decoder = new SgiDecoder();
BufferedImage image = decoder.read(imageData);
2. Process image
3. Write out Java image as TIFF
File myNewFile = new File("image.tif"); JDeli.write(image, "tif", myNewFile);
TiffEncoder encoder = new TiffEncoder();
