Description

Resizes an image by a percentage of the original image size, by the specified height/width dimensions (in pixels) or to a precise file size.

Practical Usage

Commonly used to resize a large image to a more manageable size in order for it to fit better on a web page or share it by way of email. Can also be used together with the Loop activities to resize a batch of images.

NOTE: If the image isn't already in the JPG or JPEG file format, you can usually save a significant amount of space by converting the file using the Image - Convert activity.

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 resize. 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). Wildcard characters (for example, * or ?) may be used to specify all files matching a certain mask. Multiple files and/or file masks can be specified by separating each entry with a pipe character (|) (for example, c:\temp\*.txt|c:\backup\*.bak). See File Masks & Wildcards for more details.  
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 will allow matching files found in the destination folder to be overwritten.
Resize to Text (options) No Percentage
  • RESIZETYPE="dimension"
  • RESIZETYPE="file_size"
 The criteria in which to resize the image. The available options are:
  • Dimension(s) - The image will be resized by the width and height (in pixels) specified.
  • Percentage (default) - The image will be resized by the percentage of the original size.
  • File size - The image will be resized to match the file size (in KB) specified.
Width Number Yes, if the Resize to parameter is set to Dimension(s) (Empty) WIDTH="150" The total width measured in pixels in which to resize the image. This parameter is active only if the Resize to parameter is set to Dimension(s).
Height Number Yes, if the Resize to parameter is set to Dimension(s) (Empty) HEIGHT="330" The total height measured in pixels in which to resize the image. This parameter is active only if the Resize to parameter is set to Dimension(s).
Percentage Number Yes, if the Resize to parameter is set to Percentage (Empty) PERCENTAGE="40" The percentage amount of the original size in which to resize the image (for example, 50=50% of the original size). This parameter is active only if the  Resize to parameter is set to Percentage.
Size Number Yes, if the Resize to parameter is set to File size (Empty) FILESIZE="120" The value measured in pixels in which to resize the image (for example, 120=120 pixels). This parameter is active only if the  Resize to parameter is set to File size.

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 below.

File Options

Property Type Required Default Markup Description
Exclude mask Text No (Empty)
  • EXCLUDE="*.txt"
  • EXCLUDE="*.txt|*.bak
  • EXCLUDE="c:\foldename"
 Causes this action to omit files matching the masks specified. File names or wildcard masks may be used. Multiple entries may be specified by separating them with a pipe (|) symbol (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 date/time specified. If this parameter is left blank or disabled (default), file 'newer than' dates are ignored. Click the Custom button to select from a list of pre-defined date parameters. Enable the Expression option 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 date/time specified. If this parameter is left blank or disabled (default), file 'older than' dates are ignored. Click the Custom button to select from a list of pre-defined date parameters. Enable the Expression option 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 exists in the destination, they will be overwritten. If disabled (default), files with matching names will not be overwritten, however, an error will occur 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 exists in the destination, only source files that are newer will overwrite existing files. If disabled (default), all matching files found in the destination folder will be 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 will be copied from the source. All other files, regardless of whether they match the mask or other parameter settings will be 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 will be 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 will be 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, denotes that, if present, subfolders should be 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 will be searched.
Preserve folder structure Yes/No No No KEEPFOLDERSTRUCT="NO" If selected, subfolders found in the source folder will be created in the destination folder and source files will be copied into their respective folders. If disabled (default), subfolders will not be created in the destination. Instead, source files that exist in these subfolders will be 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 should be switched OFF. The Windows archive attribute is generally used to track whether a file has been backed-up. Turning the source file's archive attribute off indicates to many backup programs that the file has already been backed-up. This parameter is disabled by default.
Match case Yes/No No No MATCHCASE="YES" If selected (default), the activity becomes case sensitive. If disabled, the activity becomes 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 which files it should act on based on whether the file's original attribute settings 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 will be 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 wish 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.
