Hi,
I’d like to draw a rectangle (X, Y, Width, Height) on a JPEG image to mask a part of the image.
I search for an example, but without success.
If anyone can help
Thanks

Hi, @vfiot.
Welcome to our forum! Thank you for using Aspose.Imaging.
Please, take a look at this article Drawing Images using Graphics|Documentation
In your case you need only change the code
try (com.aspose.imaging.Image image = com.aspose.imaging.Image.create(createOptions, 500, 500))
by
try (com.aspose.imaging.Image image = com.aspose.imaging.Image.load("your_jpeg.jpg"))
and use Graphics.drawRectangle
I hope, it will help you.
Thanks for the answer.
Here is the code I have:
//Create an instance of Image
try (com.aspose.imaging.Image image = com.aspose.imaging.Image.load(inputFile))
{
//Create and initialize an instance of Graphics
com.aspose.imaging.Graphics graphics = new com.aspose.imaging.Graphics(image);
//Clear the image surface with white color
//graphics.clear(Color.getWhite());
//Create and initialize a Pen object with blue color
com.aspose.imaging.Pen pen = new com.aspose.imaging.Pen(com.aspose.imaging.Color.getBlue());
RectangleF rec = new RectangleF();
rec.setX(0);
rec.setY(0);
rec.setHeight(200);
rec.setWidth(200);
graphics.drawRectangle(pen, rec);
// Save all changes.
image.save();
}
A rectangle is now created on the image, but I would like the backgroupd color of the rectangle to be black, not transparent.
Do you know how to do that ?
Thanks
@vfiot you can use example from Drawing Images|Documentation and apply not drawrectangle method, but fillrectangle, which draws filled rectangle with specified brush/color.
, but I would like the backgroupd color of the rectangle to be black, not transparent.
Just use Graphics.fillRectangle
Thanks for the answers, it solved my issue.
