LiveQuartz is a nice and easy-to-use image editor. It is based on layers and CoreImage filters.

You have the layers at the left and the filters at the right of the window.

To edit an image, you can open it with LiveQuartz or drag and drop it into the central view of the window and it will be added as a new layer.

Here are some key features of "LiveQuartz Image Editor":

· The brush allows you to paint with the color chosen at windows top right corner and with the tool size chosen beside.
· The eraser tool erases an image by replacing it by a transparent color. It uses the same tool size as the brush tool.
· The arrow is the layer moving tool.
· The text tool is for adding short texts. It is possible to modify the text by changing the layer name in layers list at the left of the window. You can also change the font of the newly inserted text with the button "Font" at the right of tools bar.
· The hand is for moving the view (for big images).
· The spiral tool is the tool you must use for filters. (when you select a filter that need to set a position, this tool is automatically activated)
· The selection tool is used to crop the image and to restrict painting area and erasing area.
· The magnifying glass is here to zoom and unZoom ("alt" key).
