[FinalBuilder Professional Edition]
The Lossless JPEG Transform action is used to perform certain transform operations on JPEG files without any loss of information.
Normally, simply opening and saving a JPEG file (even without performing any manipulation of the image) will results in the file being re-encoded which will result in loss of information as the JPEG algorithm is lossy - see http://en.wikipedia.org/wiki/JPEG and http://en.wikipedia.org/wiki/Lossy_compression.
The types of operations which can be performed by this action are as follows:
Auto Rotation JPG based on EXIF orientation : Most modern digital cameras can record the orientation of the camera when the photo was taken, and they record this information in the JPEG file in the EXIF properties. Using this option an automatic lossless rotation can be performed on the photo so that viewing the photo in any application will always display the photo with the correct orientation. The EXIF orientation flag is also changed so that no other automatic rotation will be performed (by this action or another application). For example, if the photo was taken in portrait, with the camera rotated 90 degrees clockwise, then the photo will automatically be rotated 90 degrees.
Rotate 90 deg clockwise : Perform a lossless 90 degrees clockwise rotation
Rotate 180 deg clockwise : Perform a lossless 180 degrees clockwise rotation
Rotate 270 deg clockwise : Perform a lossless 270 degrees clockwise rotation
Mirror Image : Perform a lossless horizontal flip
Flip Image : Perform a lossless vertical flip
Transpose Image : Mirror image across upper left to lower right axis. Same as horizontal flip and then 270 degree rotate
Transverse Transpose : Mirror image across upper right to lower left axis. Same as horizontal flip and then 90 degree rotate
Use the Files tab to specify the source images and the output location
The Image Manipulation action can either use a FileSet, or you can specify a single image file. If you want to operate on all files in a certain directory, then you need to create a FileSet using the FileSet Define action.
There are three options for the output of the image once it has been transformed in some way:
Edit Input Files : This option will operate directly on the source images and no backups will be created. Any operation performed on the images cannot be undone, so be careful!
Output to New Directory : This option will leave your source files untouched, and will create new files in the chosen directory. The preserve output directory option can be useful when using a FileSet that includes multiple directories - the directory structure of the source files will be recreated under the new directory. Only the directories deeper than the Base Directory in the FileSet will be recreated. The Fail if File already exists option will abort the action if the output file already exists and files already processed will remain.
Output to New File Name : This option can only be used when the source image is a single file. This option allows you to rename the output file.
