Examples with ImageRepresentation sun.awt.image.ImageRepresentation used on opensource projects

Example 1 with ImageRepresentation

use of sun.awt.image.ImageRepresentation in project jdk8u_jdk by JetBrains.

the class DrawImage method scaleImage.

public boolean scaleImage(SunGraphics2D sg, Image img, int x, int y, int width, int height, Color bgColor, ImageObserver observer) {
    if (!(img instanceof ToolkitImage)) {
        return scaleImage(sg, img, x, y, width, height, bgColor);
    } else {
        ToolkitImage sunimg = (ToolkitImage) img;
        if (!imageReady(sunimg, observer)) {

        }
        ImageRepresentation ir = sunimg.getImageRep();
        return ir.drawToBufImage(sg, sunimg, x, y, width, height, bgColor, observer);
    }
}

Example 2 with ImageRepresentation

use of sun.awt.image.ImageRepresentation in project jdk8u_jdk by JetBrains.

the class HTMLCodec method imageToPlatformBytes.

@Override
protected byte[] imageToPlatformBytes(Image image, long format) throws IOException {
    String mimeType = null;
    if (format == CF_PNG) {
        mimeType = "image/png";
    } else if (format == CF_JFIF) {
        mimeType = "image/jpeg";
    }
    if (mimeType != null) {
        return imageToStandardBytes(image, mimeType);
    }
    int width = 0;
    int height = 0;
    if (image instanceof ToolkitImage) {
        ImageRepresentation ir = ((ToolkitImage) image).getImageRep();
        ir.reconstruct(ImageObserver.ALLBITS);
        width = ir.getWidth();
        height = ir.getHeight();
    } else {
        width = image.getWidth(null);
        height = image.getHeight(null);
    }
    // Fix for 4919639.
    // Some Windows native applications (e.g. clipbrd.exe) do not handle
    // 32-bpp DIBs correctly.
    // As a workaround we switched to 24-bpp DIBs.
    // MSDN prescribes that the bitmap array for a 24-bpp should consist of
    // 3-byte triplets representing blue, green and red components of a
    // pixel respectively. Additionally each scan line must be padded with
    // zeroes to end on a LONG data-type boundary. LONG is always 32-bit.
    // We render the given Image to a BufferedImage of type TYPE_3BYTE_BGR
    // with non-default scanline stride and pass the resulting data buffer
    // to the native code to fill the BITMAPINFO structure.
    int mod = (width * 3) % 4;
    int pad = mod > 0 ? 4 - mod : 0;
    ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_sRGB);

    int[] bOffs = { 2, 1, 0 };
    ColorModel colorModel = new ComponentColorModel(cs, nBits, false, false, Transparency.OPAQUE, DataBuffer.TYPE_BYTE);
    WritableRaster raster = Raster.createInterleavedRaster(DataBuffer.TYPE_BYTE, width, height, width * 3 + pad, 3, bOffs, null);
    BufferedImage bimage = new BufferedImage(colorModel, raster, false, null);
    // Some Windows native applications (e.g. clipbrd.exe) do not understand
    // top-down DIBs.
    // So we flip the image vertically and create a bottom-up DIB.
    AffineTransform imageFlipTransform = new AffineTransform(1, 0, 0, -1, 0, height);
    Graphics2D g2d = bimage.createGraphics();
    try {

    byte[] imageData = buffer.getData();
    return imageDataToPlatformImageBytes(imageData, width, height, format);
