Overview

Rotates an image by 90, 180, or the specified amount of degrees. Can also be used to automatically deskew a skewed image.

Practical usage

Used to correctly display an image taken with a camera at an angle or deskew a skewed image.

Parameters

General

Property Type Required Default Markup Description
Source Text Yes (Empty) SOURCEIMAGE="c:\temp\source.jpg" The path and file name of the source image to rotate. Supported image formats are JPG, JPEG, PNG, BMP, TIF, TIFF, and GIF.  This can be a fully qualified path and file name (preferred) or a single file (requires use of the File System - Change folder activity). You can use wildcard characters (for example, * or ?) to specify all files matching a certain mask. You can specify multiple files and file masks by separating each entry with a pipe (|). For example, c:\temp\*.txt|c:\backup\*.bak. See File Masks & Wildcards for more information.
Destination Text Yes (Empty) DESTINATIONIMAGE="c:\temp\dest.jpg" The path and file name of the destination image. This allows you to save your file under a new path, name, and/or type to avoid overwriting the source (original) file. To overwrite the source file, enter its original path and file name.
NOTE: If performing an overwrite, make sure to set the Overwrite if exists parameter to YES (enabled) in the File Options properties. This allows matching files found in the destination folder to be overwritten.
Rotate to Text (options) No Right 90
  • ROTATEANGLE="180"
  • ROTATEANGLE="-90"
  • ROTATEANGEL="Custom"
  • ROTATEANGEL="deskew"
 The degree in which to rotate the image. The available options are:
  • Right 90 (Default) - The image is rotated 90 degrees to the right.

  • 180 - The image is rotated 180 degrees

  • Left 90 - The image is rotated 90 degrees to the left.

  • Custom - The image is rotated at the amount of degrees entered. Selecting this option provides a Rotation angle box to allow entry of a custom value (for example, -120=120 degrees to the left. 130=130 degrees to the right).

  • Deskew - Automatically deskews the image. Deskew is the process of straightening an image that is slanting too far in one direction, or one that is misaligned. A skewed image is normally one that has been scanned or photographed crookedly.

Advanced

Property Type Required Default Markup Description
Create and populate dataset Text No (Empty) DATASET="datasetName" The name of a dataset to create and populate with information about this activity's results. For more details, see Datasets.

File Options

Property Type Required Default Markup Description
Exclude mask Text No (Empty)
  • EXCLUDE="*.txt"
  • EXCLUDE="*.txt|*.bak
  • EXCLUDE="c:\foldename"
 Omits files matching the specified masks. You can use file names or wildcard masks. You can specify multiple entries by separating them with a pipe (|) (for example, *.txt|*.bak).
Regular expression Yes/No No No RE="YES" Specifies whether the Exclude mask parameter is a regular expression. If disabled (default), the Exclude mask parameter contains literal text.
Only if newer than Date No (Empty) ISNEWERTHAN="%DateSerial(2001,10,12) + TimeSerial(00,00,00)%" If enabled, causes this action to only act on files that are newer than the specified date/time. If this parameter is left blank or disabled (default), file 'newer than' dates are ignored. Click Custom to select from a list of pre-defined date parameters. Select the Expression check box to allow entry of a date/time expression.
Only if older than Date No (Empty) ISOLDERTHAN="%DateSerial(2001,10,12) + TimeSerial(00,00,00)%" If enabled, causes this action to only act on files that are older than the specified date/time. If this parameter is left blank or disabled (default), files with older than dates are ignored. Click Custom to select from a list of pre-defined date parameters. Select the Expression check box to allow entry of a date/time expression.
Overwrite if exists Yes/No No No OVERWRITE="YES" If selected, indicates that, if files with matching names already exist in the destination, they are overwritten. If disabled (default), files with matching names are not overwritten, however, an error occurs during runtime stating a file with the same name already exists.
Only if newer Yes/No No No ISNEWER="YES" If selected, indicates that, if files with matching names already exist in the destination, only source files that are newer overwrite existing files. If disabled (default), all matching files found in the destination folder are overwritten regardless of their date properties. This parameter is active only if the Overwrite if Exists parameter is selected.
Only if exists in destination Yes/No No No ONLYIFEXIST="YES" If selected, only files that already exist in the destination are copied from the source. All other files, regardless of whether they match the mask or other parameter settings are bypassed. This parameter is disabled by default and becomes active only if the Overwrite if Exist parameter is selected.
Overwrite read-only files Yes/No No No OVERWRITEREADONLY="YES" If selected, matching files found in the destination folder are overwritten even if they are marked with the read-only attribute. If disabled (default), read-only files are not overwritten. This parameter is active only if the Overwrite if Exist parameter is selected.
Overwrite hidden files Yes/No No No OVERWRITEHIDDEN="YES" If selected, matching files found in the destination folder are overwritten even if they are marked with the hidden attribute. If disabled (default), hidden files are not overwritten. This parameter is active only if the Overwrite if Exist parameter is selected.
Include subfolders Yes/No No No SUBFOLDERS="YES" If selected, subfolders are searched for files matching the mask specified in the Source parameter. If disabled (default), subfolders are ignored. Only files that exist in the root of the source folder are searched.
Preserve folder structure Yes/No No No KEEPFOLDERSTRUCT="NO" If selected, subfolders found in the source folder are created in the destination folder and source files are copied into their respective folders. If disabled (default), subfolders are not created in the destination. Instead, source files that exist in these subfolders are copied into the root of the destination folder. This parameter is active only if the Include subfolders parameter is selected.
Turn archive attribute off Yes/No No No ARCHIVETURNOFF="YES" If selected, specifies that the archive attribute of the source files is OFF. The Windows archive attribute is generally used to track whether a file is backed up. Disabling the source file archive attribute indicates to many backup programs that the file is backed up. This parameter is disabled by default.
Match case Yes/No No No MATCHCASE="YES" If selected (default), the activity is case sensitive. If disabled, the activity is case insensitive, whereas, it does not distinguish between uppercase and lowercase characters.

File Attributes

Property Type Required Default Markup Description
Attributes Text (Options) No (Empty)
  • ATTRFILTER="+R+A-H" (read-only & archive files will be affected but not hidden files)
  • ATTRFILTER="-S+H+E" (hidden and encrypted files will be affected but not system files)
 Instructs the activity to filter the files it acts on based on whether the original attribute settings of the file match the attribute settings specified in this parameter. For example, if the Read-only attribute is set to Off (in visual mode) or "-R" (in AML mode) , only source files with the Read-only attribute turned off are affected. Source files with Read-only turned on will be ignored. In visual mode, a group of controls are provided to assist in the selection of attribute settings. In AML mode, a single text item must be entered that contains the original attribute mask of the files you want to affect. Available options are:
  • R—Read-only - Specifying On or "+R" causes files with this attribute turned on to be included. Specifying Off or "-R" causes files with this attribute turned off to be included. Specifying Doesn't matter or excluding the letter (default) causes this attribute to be ignored.
  • A—Archive - Specifying On or "+A" causes files with this attribute turned on to be included. Specifying Off or "-A" causes files with this attribute turned off to be included. Specifying Doesn't matter or excluding the letter (default) causes this attribute to be ignored.
  • S—System - Specifying On or "+S" causes files with this attribute turned on to be included. Specifying Off or "-S" causes files with this attribute turned off to be included. Specifying Doesn't matter or excluding the letter (default) causes this attribute to be ignored.
  • H—Hidden - Specifying On or "+H" causes files with this attribute turned on to be included. Specifying Off or "-H" causes files with this attribute turned off to be included. Specifying Doesn't matter or excluding the letter (default) causes this attribute to be ignored.
  • C—Compression - Specifying On or "+C" causes files with this attribute turned on to be included. Specifying Off or "-C" causes files with this attribute turned off to be included. Specifying Doesn't matter or excluding the letter (default) causes this attribute to be ignored.
  • E-Encrypted - Specifying On or "+E" causes files with this attribute turned on to be included. Specifying Off or "-E" causes files with this attribute turned off to be included. Specifying Doesn't matter or excluding the letter (default) causes this attribute to be ignored.
