Java API for Image Processing

Imaging API is a library offering advanced image processing features. Developers can create, edit or convert images in their own application. Also Aspose. Imaging library supports drawing and work with graphic primitives. Image export and conversion (including uniform multi-page image processing) is the one of API core features along with image transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing) and memory optimization strategies.

Platform Independence

Aspose.Imaging for Java can be virtually run in any OS where Java is installed (since JDK 1.6)

Windows (since 7)
Linux
MacOS
Any OS where Java is installed.

Aspose.Imaging works for both x86 and x64 versions of the above listed operating systems.

Note: In Linux OS, it is recommended to install the package with Microsoft compatible fonts (e.g. sudo apt-get install ttf-mscorefonts-installer).

Get Started with Aspose.Imaging for Java

Aspose hosts all Java APIs at the Aspose Repository. You can easily use Aspose.BarCode for Java API directly in your Maven projects with simple configurations. For the detailed instructions please visit Installing Aspose.Imaging for Java from Maven Repository documentation page.

Resize a JPG Image

try (Image image = Image.load(dir + "template.jpg"))
{
    image.resize(300, 300);
    image.save(dir + "output.jpg");
}

Create & Manipulate PNG via API

// image width and height
int width = 500;
int height = 300;

// where created image to store
String path = "createdImage.png";
// create options
try (PngOptions options = new PngOptions())
{
	options.setSource(new FileCreateSource(path, false));
	try (PngImage image = (PngImage)Image.create(options, width, height))
	{          
		// create and initialize an instance of Graphics class 
		// and Clear Graphics surface
		Graphics graphic = new Graphics(image);
		graphic.clear(Color.getGreen());
		// draw line on image
		graphic.drawLine(new Pen(Color.getBlue()), 9, 9, 90, 90);        

		// resize image
		int newWidth = 400;
		image.resizeWidthProportionally(newWidth, ResizeType.LanczosResample);  

		// crop the image to specified area
		com.aspose.imaging.Rectangle area = new com.aspose.imaging.Rectangle(10,10,200,200);    
		image.crop(area);
	   
		image.save();
	}
}

ResolutionSetting has no effect on outputs

I want to convert an image (png, jpg, jpeg, tiff) to TIFF with a new resolution. I tried a number of examples in this repo and the resolution of outputs remained unchanged.
SavingRasterImageToTIFFWithCompression.java

     TiffOptions options = new TiffOptions(TiffExpectedFormat.Default);
        options.setBitsPerSample(new int[] { 8, 8, 8 });
        options.setPhotometric(TiffPhotometrics.Rgb);
      // already tried        options.setResolutionSettings(new ResolutionSetting(100, 100));
        options.setXresolution(new TiffRational(200));
        options.setYresolution(new TiffRational(200));
        options.setResolutionUnit(TiffResolutionUnits.Inch);

I also looked into other image outputs like JPEG. They have the same problem
ConvertTIFFToJPEG.java


                JpegOptions saveOptions = new JpegOptions();
                // The provided tiff's resolution is (Horizontal=200,Vertical=100), I put some numbers and outputs didn't change
                saveOptions.setResolutionSettings(new ResolutionSetting(tiffFrame.getHorizontalResolution(), tiffFrame.getVerticalResolution()));

SettingResolution.java. This one has a bug. It always produced that image

            // Create an instance of PngOptions, Set the horizontal & vertical resolutions and Save the result on disc
            PngOptions options = new PngOptions();
            options.setResolutionSettings(new ResolutionSetting(72, 96));
            png.save(Utils.getOutDir() + "SettingResolution_output.png", options);
