Generate & Edit Images inside Java Apps

Aspose.Imaging for Java enables software developers to create new images from the scratch with just a couple of lines of Java code. The library has provided several impotent classes for creating and managing images. It supports numerous options for creating images in various formats such as BMP, GIF, JPEG, PNG, TIFF, PSD, DICOM, TGA, ICO, EMZ, WMZ, and many more. Moreover, you can create images by setting a path, creating an image via stream, resizing images, drawing objects on the image, updating the content of an image and saving images to disk, adjusting image brightness, applying contrast or gamma to image, apply blur effects to an image, check image transparency and so on.

Creating an Image by Setting a Path via Java API?

// The path to the documents directory.
String dataDir = "D:/dataDir/";
// Creates an instance of BmpOptions and set its various properties
BmpOptions imageOptions = new BmpOptions();

// Define the source property for the instance of BmpOptions  Second boolean parameter determines if the file is temporal or not
imageOptions.setSource(new FileCreateSource(dataDir + "CreatingAnImageBySettingPath_out.bmp", false));

    // Creates an instance of Image and call Create method by passing the BmpOptions object
    try (Image image = Image.create(imageOptions, 500, 500))
        image.save(dataDir + "CreatingAnImageBySettingPath1_out.bmp");

Image Conversion to Other Formats via Java API

Aspose.Imaging for Java gives software developers the power to convert different types of images to other supported file formats using Java commands. The library has provided several functions for converting images from one format to another, including JPEG, BMP, TIFF, GIF, PNG, DICOM, TGA, ICO, EMZ, WMZ, WebP, SVG, and more. The library also supports converting images to multi-page TIFFs, saving individual pages of a TIFF as separate images, and converting images to PDFs.

Convert TIFF to JPEG image via Java API

// The path to the documents directory.
	String dataDir = Utils.getSharedDataDir(ConvertTIFFToJPEG.class) + "ManipulatingJPEGImages/";
TiffImage tiffImage = (TiffImage)Image.load(dataDir + "source2.tif");
        int i = 0;
        for (TiffFrame tiffFrame : tiffImage.getFrames())
            JpegOptions saveOptions = new JpegOptions();
            saveOptions.setResolutionSettings(new ResolutionSetting(tiffFrame.getHorizontalResolution(), tiffFrame.getVerticalResolution()));

            TiffOptions frameOptions = tiffFrame.getFrameOptions();
            if (frameOptions != null)
                // Set the resolution unit explicitly.
                switch (frameOptions.getResolutionUnit())
                    case TiffResolutionUnits.None:

                    case TiffResolutionUnits.Inch:

                    case TiffResolutionUnits.Centimeter:

                        throw new RuntimeException("Current resolution unit is unsupported!");

            String fileName = "source2.tif.frame." + (i++) + "." 
                    + ResolutionUnit.toString(ResolutionUnit.class, saveOptions.getResolutionUnit()) + ".jpg";
            tiffFrame.save(dataDir + fileName, saveOptions);

Manipulate Images via Java API

Aspose.Imaging for Java makes it easy for computer programmer to access and manipulate existing images with ease. There are several functions part of the library for handling image manipulation, such as update image properties, draw vector graphics, multipage image handling, delete or update image background, images merging (JPG to JPG, JPG to PDF merge, JPG to PNG), image cropping, rotate images , images resizing, deskew images, adding watermark to image, draw raster images on vector images and so on.

Apply Median Filter on Images via Java API

// Load the noisy image 
Image image = Image.load(dataDir + "aspose-logo.gif");
    // caste the image into RasterImage
    RasterImage rasterImage = (RasterImage) image;

    if (rasterImage == null)

    // Create an instance of MedianFilterOptions class and set the size.
    MedianFilterOptions options = new MedianFilterOptions(4);

    // Apply MedianFilterOptions filter to RasterImage object.
    rasterImage.filter(image.getBounds(), options);

    // Save the resultant image
    image.save(dataDir + "median_test_denoise_out.gif");

Rotate and Resize Images via Java API

Aspose.Imaging for Java allows software developers to programmatically rotate and resize images inside their own Java applications. Cropping is a very useful technique that can be used to cut out some portion of an image to increase the focus on a particular area. The library has provided several features related to images rotation and resizing, such as cropping images by shifts, images cropping by rectangle, vector image cropping, rotating images by 90/180/270 degrees, flip images horizontally or vertically, rotating images on a specified angle, resize webp image, resize an image proportionally and many more.  

How to Crop an Image by Shifts via Java API?

u// The path to the documents directory.
String dataDir = "dataDir/jpeg/";

// Load an existing image into an instance of RasterImage class
try (RasterImage rasterImage = (RasterImage)Image.load(dataDir + "aspose-logo.jpg"))
    // Before cropping, the image should be cached for better performance
    if (!rasterImage.isCached())

    // Define shift values for all four sides
    int leftShift = 10;
    int rightShift = 10;
    int topShift = 10;
    int bottomShift = 10;

    // Based on the shift values, apply the cropping on image Crop method will shift the image bounds toward the center of image and Save the results to disk
    rasterImage.crop(leftShift, rightShift, topShift, bottomShift);
    rasterImage.save(dataDir + "CroppingByShifts_out.jpg");
