Smarter Signature Positioning (Completed)

2018-10-10 12_07_56-Help2.docx - Word

You can drag to move around Signature to position in the photo. Currently it remembers the position from the Top Left corner.

In this example, signature is positioned right top corner. For panorama photo, the signature is positioned like above after calculation photo’s width/height ratio originating from Top Left corner.

However, you might expect the signature to be positioned on the Right Top corner no matter what width/height ratio photo is.

System can be smarter to detect your positioning preference and meet your expectation.

Also, we can add specific position that you can select without dragging by yourself, such as “Center”, “Left Top”, “Right Top”, “Left bottom”, “Right Bottom”, “Top Center”, “Bottom Center”, etc. System takes care of the position for you.

Image Watermark (Completed)

Current app allows only text signature. We can allow Image watermark. You can select image for watermark and configure the opacity, size and position.

Signature Text Alignment (Completed)

You can type multiple lines of signature text. However, there is no alignment such as “Right” and “Center”. Alignment option can be added.

Apply Result Image Viewer with Slider (Completed)

After applying to photos, you can view the result in the Apply page. You can scroll to navigate the photos like Windows 10 Photos viewer app.

This must be enough for this app because you can open Windows explorers to view all photos in the Target folder. However, we can improve the viewer navigation with slider which you can slide to any position of the photo to find a specific photo.

This viewer improvement can be added with new option that allows you to specify the Order of the photos. Photos in viewer could be ordered by Name or Date Taken or etc. This can help you navigate photos.
