SCEditShot 4+

Simple photo editing program. Allows most common image file formats to be loaded from, edited, and saved to the Photos library. App can pan, zoom, rotate, and mirror the image. A frame can be used to crop the image before or after saving. App provides both freehand and standard frame dimensions; use picker at bottom-right for standard frames and long-press then pan to define custom frames dynamically. Once defined, a frame can be further adjusted using handles at frame mid-points.

Other features allow return to full screen, toggling the frame on/off, cropping to framed area, reloading the current image (say after you already cropped it), removing the currently viewed image, loading a new image (without first removing the current one), and locking an image's frame, size, and/or position so it won't be accidentally changed. Lastly, use the standard gestures to pan, pinch (zoom), rotate, and swipe (mirror) the current image.

This application is intended to be used with SCSnapShot, SCSnapShotIP, and SCSnapShotRT after photos have been captured but which you still may have additional light editing to do before storing or sharing.
