Examples of ar.com.hjg.pngj.chunks.PngMetadata

ar.com.hjg.pngj.chunks.PngMetadata
We consider "image metadata" every info inside the image except for the most basic image info (IHDR chunk - ImageInfo class) and the pixels values.
This includes the palette (if present) and all the ancillary chunks
This class provides a wrapper over the collection of chunks of a image (read or to write) and provides some high level methods to access them

    
    public PNGWriter(File outputFile, int cols, int rows) {
      imgInfo = new ImageInfo(cols, rows, 8, false);
      writer = new PngWriter(outputFile, imgInfo, true);
      
      PngMetadata metaData = writer.getMetadata();
      metaData.setTimeNow();
      metaData.setText(PngChunkTextVar.KEY_Software, "OSM2World");
    }
