PhotoGlyph

Press the 'Select' button to choose a photo from your library. If the photo has metadata, then you can press the 'Annotate' button to superimpose the location, direction and date/time on the bottom left of the image (note: when you save to the Photo Library, you can copy and paste this text from the image). Double tap or pinch to zoom in and out. Select either the 'Pictograph' or 'Petroglyph' depending on the subject of your photo to enhance its features. Press the 'Undo' button to revert changes. When finished, you can save the new image to your Photo Library. Note, depending on the color composition of pictographs, the 'Petroglyph' option might yield better results.
