Hi , im not able to set image Opacity. Heres my code
Document doc = new Document();
DocumentBuilder documentBuilder = new DocumentBuilder(doc);
Shape imageShape = documentBuilder.insertImage("sampleImg.jpg");
imageShape.setFillColor(Color.BLACK);
imageShape.getFill().setOpacity(0.5f);
doc.save("test.docx");
Kindly Help
Unfortunately, the Aspose.Words API does not currently support setting the opacity or transparency of image shapes directly. This limitation has been noted, and there is an issue logged for this feature (WORDSNET-19658).
As a workaround, you can use the Aspose.Imaging for Java API to adjust the transparency of your image before inserting it into the Word document. Here’s a brief guide on how to do this:
Here’s a sample code snippet to illustrate this approach:
import com.aspose.imaging.Image;
import com.aspose.imaging.ImageOptions;
import com.aspose.imaging.fileformats.png.PngOptions;
import com.aspose.imaging.imageoptions.PngOptions;
import com.aspose.words.Document;
import com.aspose.words.DocumentBuilder;
import com.aspose.words.Shape;
public class ImageOpacityExample {
public static void main(String[] args) {
// Load the image using Aspose.Imaging
Image image = Image.load("sampleImg.jpg");
// Set the transparency (0.0f is fully transparent, 1.0f is fully opaque)
image.getPalette().setTransparency(0.5f);
// Save the modified image
image.save("modifiedImg.png", new PngOptions());
// Now, use Aspose.Words to insert the modified image
Document doc = new Document();
DocumentBuilder documentBuilder = new DocumentBuilder(doc);
Shape imageShape = documentBuilder.insertImage("modifiedImg.png");
doc.save("test.docx");
}
}
Make sure to include the necessary Aspose.Imaging and Aspose.Words libraries in your project to use the above code.
For more details on manipulating image transparency, you can refer to the documentation on Specifying Transparency for PNG Images.
If you have any further questions or need additional assistance, feel free to ask!
@VishalPro Please use the following code:
Document doc = new Document();
DocumentBuilder documentBuilder = new DocumentBuilder(doc);
Shape imageShape = documentBuilder.insertShape(ShapeType.RECTANGLE, 100, 100);
imageShape.getFill().setImage("C:\\Temp\\test.png");
imageShape.getFill().setOpacity(0.5f);
doc.save("C:\\temp\\out.docx");
@alexey.noskov Im not able to find setImage method in my aspose library . Im currently using v_20_12_0 Version.
