Hi;

I am converting a file from one format to PNG and the DPI and bits/pixel are not
carrying over. The DPI is always -1 and the PNG is always 24 DPI.

Partial code here: ImageInputStream imageInput = ImageIO.createImageInputStream(new
ByteArrayInputStream(image)); Iterator it = ImageIO.getImageReaders("bmp"); ImageReader reader = null; while(it.hasNext()) { Object obj = it.next(); if (! (obj instanceof ImageReader)) continue; reader = (ImageReader) obj; if (reader.getOriginatingProvider().isStandardImageMetadataFormatSupported()) break; } reader.setInput(imageInput); IIOMetadata meta = reader.getImageMetadata(0);

it = ImageIO.getImageWritersByFormatName(HtmlImage.typeToStr(formats[0])); ImageWriter writer = null; while(it.hasNext()) { writer = (ImageWriter)it.next(); if (writer.getOriginatingProvider().isStandardImageMetadataFormatSupported()) break; } ImageWriteParam writeParam = writer.getDefaultWriteParam(); if (writeParam.canWriteCompressed()) { writeParam.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); writeParam.setCompressionQuality(0.95f); }

RenderedImage ri = reader.read(0); ByteArrayOutputStream out = new ByteArrayOutputStream(); MemoryCacheImageOutputStream mcios = new MemoryCacheImageOutputStream(out); writer.setOutput(mcios); writer.write(null, new IIOImage(ri, null, meta), writeParam);

reader.dispose(); imageInput.close(); writer.dispose(); mcios.close();
