Aspose.Imaging for Java
Aspose.Imaging for Java is a high-performance and well-documented imaging API that provides the most flexible group of images processing routines for the developers to create, manipulate, save and convert images in their Java applications, without the need of an image editor.
Aspose.Imaging provides features that go beyond the native capabilities of the development platform. It works independent of other applications and allows saving to Adobe Photoshop® native format without having Photoshop or any other image editor installed on the machine.

Inter-convert Image Formats
Along with rich set of image processing routines, Aspose.Imaging for Java also provides an array of advanced algorithms that makes it an all-in-one solution for image format conversion. These algorithms are encapsulated in specialized classes that are simple to use and can export images to conventional raster image formats along with SVG, PSD, WMF, EMF, DjVu, DICOM, DNG & WebP formats.
Save image in different formats - Java
// load image to be converted Image image = Image.load(dir + "template.jpg"); // save in PSD format image.save(dir + "output.psd", new PsdOptions()); // save in TIFF format image.save(dir + "output.tiff", new TiffOptions(TiffExpectedFormat.Default)); // save in SVG format SvgOptions svgOptions = new SvgOptions(); SvgRasterizationOptions svgRasterizationOptions = new SvgRasterizationOptions(); svgRasterizationOptions.setPageWidth(image.getWidth()); svgRasterizationOptions.setPageHeight(image.getHeight()); svgOptions.setVectorRasterizationOptions(svgRasterizationOptions); image.save(dir + "output.svg", svgOptions);
Draw Images On the Fly
Aspose.Imaging for Java supports an advanced set of drawing features along with the core functionality. Developers can draw on the image surface either by manipulating the pixel information or by using the advanced functionality like graphics and paths.
Aspose.Imaging for Java API enables you to easily draw lines, curves, rectangles & other geometric shapes, fill closed shapes with solid colors or gradients & textures, draw text with options for fine control over the font and draw images by loading existing image data.
Register Custom File Formats
Another promising feature that Aspose.Imaging for Java API provides is to register custom image formats. Aspose.Imaging for Java allows the developers to register new custom file formats to create, open or export to by using one of Aspose.Imaging for Java registry APIs for corresponding operation. This feature allows the addition of new file formats which can be used for drawing and export purposes.
Transform Images to Grayscale
Grayscaling is the process of converting a continuous-tone image to an image with discontinues gray shades. With Aspose.Imaging, transforming any image to its grayscale representation is as simple as calling a single method on the supplied RasterImage.
Transform image to grayscale - Java
// load the image to be transformed Image image = Image.load(dir + "template.png"); // cast the image to RasterCachedImage RasterImage rasterImage = (RasterImage) image; // transform image to its grayscale representation rasterImage.grayscale(); // save the resultant image rasterImage.save(dir + "output.png");
Recover Data from Broken TIFF Files
Aspose.Imaging provides extensive support for TIFF file format including the feature of data recovery, using which the developers can extract the data from a broken TIFF image with some loss. The data recovery allows loading a TIFF file that has improper data layout or corrupted data strips. Data recovery replaces the corrupted data with any color, and the resultant image can be further processed without experiencing errors.
