IMAGING-34566 Support the Jpeg Compression Method while creating/saving TIFF images We now support conversion to Tiff with jpeg compression.

Usage example:

 TiffOptions outputSettings = new TiffOptions(); outputSettings.setCompression(TiffCompressions.Jpeg); outputSettings.setPhotometric(TiffPhotometrics.Rgb); outputSettings.setBitsPerSample(new int\[\] { 8, 8, 8 }); String path = sourceFolder + "34606_02.bmp"; Image image = Image.load(path); image.save(destFolder + "34566_02.tif", outputSettings); IMAGING-34362 [Java] Check if a license has been properly set Correct code to use: com.aspose.imaging.License.isLicensed() IMAGING-34483 Support Jpeg compression for Psd thumbnails String path = sourceFolder + "34483_Cmyk16Bits.psd"; Boolean foundResource = false; PsdImage image = (PsdImage)Image.load(path); { for(ResourceBlock resource : image.getImageResources()) { if (resource instanceof ThumbnailResource) { ThumbnailResource thumbnail = (ThumbnailResource)resource; if (thumbnail.getFormat() == ThumbnailFormat.kJpegRGB) { BmpImage thumnailImage = new BmpImage(thumbnail.getWidth(), thumbnail.getHeight()); thumnailImage.savePixels(thumnailImage.getBounds(), thumbnail.getThumbnailData()); thumnailImage.save(destFolder + "34483_test.bmp"); foundResource = true; } } } } IMAGING-34410 Add transparent and background color support for images New interface for transparent and background color setting. Previously transparent color setting was available only for png images via TransparentColorSetting class in PngOptions. From now user can set image background color and transparent color via image properties. Transparent color is a color, which will be substituted with underlying pixel color by viewers. String path = sourceFolder + "34410_4.gif"; RasterImage image = (RasterImage)Image.load(path); image.setBackgroundColor(Color.getRed()); image.setTransparentColor(Color.getBlack()); image.save(destFolder + "34410_image.png", new PngOptions()); IMAGING-34372 Export more than one layouts of CAD drawings to PDF & RasterImages String fileName = sourceFolder + "34372_Layout_active_model_.dxf"; String outPath = destFolder + "34372_Layout_active_model_.pdf"; Image image = Image.load(fileName); { ImageOptionsBase options = new PdfOptions(); CadRasterizationOptions cadRasterizationOptions = new CadRasterizationOptions(); cadRasterizationOptions.setPageHeight(1600); cadRasterizationOptions.setPageWidth(1600); cadRasterizationOptions.setScaleMethod(ScaleType.GrowToFit); options.setVectorRasterizationOptions(cadRasterizationOptions); image.save(outPath, options); } IMAGING-34327 Support for PSD files having CMYK color mode String path = sourceFolder + "34327_Cmyk16Bits.psd"; PsdImage image = (PsdImage)Image.load(path); { if (image.getColorMode() \!= ColorModes.CMYK) { Assert.fail("Not a CMYK Psd"); } image.save(destFolder + "34327_output.bmp", new BmpOptions()); } IMAGING-34485 Improve JpegOptions and JpegImage with new useful properties for export String path = sourceFolder + "34119_emd.jpg"; JpegImage image = (JpegImage)Image.load(path); { JpegOptions options = new JpegOptions(); options.setCMYKColorProfile(null); options.setRGBColorProfile(null); options.setExifData(new JpegExifData()); options.setJfif(new JFIFData()); image.save(destFolder + "34485_output.jpg", options); } Set of jpeg options properties: CMYKColorProfile - set destination cmyk icc color profile. Affects image pixel encoding process. RGBColorProfile - set destination rgb icc color profile. Affects image pixel encoding process ExifData - set exif data for image. Jfif - set jfif data for image. Public API changes: IMAGING-33618 Java BufferedImage support A new API member has been added. The following example demonstrates the 'fromJava' method added: String path = "%temp%"; BufferedImage s = new BufferedImage(100, 100, BufferedImage.TYPE_INT_RGB); Graphics2D gr = s.createGraphics(); gr.drawString("hello", 20, 20); gr.dispose(); // Here goes conversion from buffered image to Aspose image. Image img = ImageExtensions.fromJava(s); img.save(path + "/IMAGING-33618.png"); img.dispose();
