To Mirror an Image Using the Mirror Tool
Click the Mirror icon (
Choose a data point on the image to mirror.
Note: Only file formats which support a transformation matrix will maintain mirroring operations stored in the transformation matrix. For all file formats without a transformation matrix, such as standard TIFF or BMP files, Raster Manager adds a worldfile. However, if this TIFF or BMP are opened in an application where worldfiles are not supported, the information in the transformation matrix will not be applied to the image.
