You are writing a review on a desktop app and want to point out where the option of the app people should go to is in a screenshot. You went out for sightseeing and took many photos of places of interest. You shared them with your friends. Labeling the famous buildings will make your friends quickly find them in the photos. You have some natural landscape photographs and need to fine-tune some photo effects.

After launching Photo Stitcher, you will be greeted by a sleek and clean window. The window mainly consists of two panels. One panel is the preview panel, which takes up most of the window. It is where you can zoom and pan the stitched image, modify its width and height, and edit it. The other panel is on the right side of the window. A series of tools are located in this panel, which you can use to edit the stitched image. You can adjust the direction in which you stitch images. Besides, you can add borders between the images to be stitched as well as outer borders to the stitched image. In addition, you can crop the stitched image to highlight the focal point of the stitched image. What's more, you can draw free-form shapes, arrows, and squares to make annotations. Moreover, if you want to protect your copyright, you can watermark the stitched image by adding a watermark to the bottom of the stitched image or full-page watermarks to its whole area. Furthermore, you can use different types of mosaics to hide the sensitive information in the stitched image. You are also given the ability to customize the colors of the shape, watermark, and border.

Now, let's dive into the part of how to use Photo Stitcher to annotate an image.

How to annotate an image with Photo Stitcher

Step 1.

  • Throw your image into the drop box saying "Drag and Drop Your Photo Here". Or click on "File"->"Add Photo" to add the image into the program. You can also click on the "Add" button to import the image. To remove the imported image, click on the "Remove" button next to the "Add" button. When the image is loaded into the program, perhaps it looks very large and does not fit the preview panel. Click on "Edit"->"Fit Screen". Then, move the zooming slider at the bottom left corner of the window to zoom it out.

Step 2.

  • Navigate to the "Editing Tools" section in the right-side panel. Click on the "Free-Hand Line" icon. Then, click on the ellipsis icon. There are three options including "Thin", "Medium", and "Thick". Choose one from the three options. I suggest you choose "Thin". Pick one color on the palette. Write words by drawing free-hand lines as the note on the image. Click on the "Arrow" icon. Then, choose "Thick" in the ellipsis menu. Pick one color as the color of the arrow. Draw an arrow beside the words and make it point to the object you want to note.
