This tool allows you to toggle between shape editing and drawing directly on the image.
· In shape editing mode, indicated by this button appearance: , anything you draw on the image may be later selected and moved, hidden, resized, rotated etc. This mode is best for drawing large shapes over an image, like circle, rectangles, long lines and arrows or even freehand scribbling, text and callout items etc. Shapes and text items drawn in this mode may even extend beyond the image onto the background of HyperSnap window, and later moved to the image if needed, or you may expand the image area later to encompass them, if you want them saved to a standard image format like JPEG, PNG, GIF, BMP.
· In “drawing directly on image” mode , the drawing operations change the underlying image at once – if you draw a line, arrow, circle, text etc. in this mode, it cannot be edited or changed later any more. You can only undo the entire operation and repeat it if necessary. This mode is best for correcting individual pixels on an image, drawing small icons where the exact placement of every pixel counts etc.
