Stitching images together

Image stitching allows you to seamlessly join 2D images. For instance, you can scan a large image in smaller, overlapping pieces and reassemble them.

You can stitch images together to create a single, large image. This image has been scanned in four sections and stitched.

In Corel PHOTO-PAINT, you can stitch multiple images interactively. You can select, move, and rotate the images, as well as change your view of them to allow more precise positioning. As you position the images, overlapping areas will turn black to signal that you have aligned the edges correctly. You can then save the stitched images as a single, flattened image, or as objects that you can continue to edit individually.

You can stitch images in all color modes except black-and-white, duotone, 16-bit grayscale, 48-bit RGB, and multichannel. If the selected images use the same color mode, except paletted color mode, the new file will use that color mode as well. If the selected files use a different color mode, or are all paletted color mode, the new file uses RGB color mode. For more information about color modes, see Changing color modes.

To stitch images together

Down button

5 .

Click OK.

6 .

In the Image stitch dialog box, click the Selection tool

7 .

In the image stitch window, drag an image to align it with another image.
