JDeli is able to read and write images as PNG files, giving a complete PNG converter between PNG file format and lots of other image file formats.
JDeli can do this in ONE step with the convert method or separately read or write the PNG image if you want to process the image in Java.
java -jar jdeli.jar --convert png "inputFileOrDir" "outputDir"
JDeli.convert(File inFile, File outFile); JDeli.convert(InputStream inFile, OutputStream outfile, String format); byte outputData=JDeli.convert(byte inputData, String format);
An additional set of methods allow values to be passed in which can give more control over conversion, depending on the image formats being converted (ie different image compression options).
