ImageEngine Documentation

7. Using ImageEngine

7.2. Extract

The Extract function creates a PDF document that only contains the images from the source PDF document.

To apply the Extract function to the front document of Adobe Acrobat, choose the menu "ImageEngine" –> "Extract…".

Now the document dialog appears, allowing the user to adjust whether the function is to be applied to the entire document or to a range of coherent pages. There is also a button available to change the settings of the Extract function.

To cancel the Extract function, press the "Cancel" button.

To start the Extract function with the desired document, press the "Extract…" button.

To apply the Extract function to a PDF document, stored as a file, choose the menu "ImageEngine" –> "Extract from File…". An Open dialog appears, which allows to select the desired PDF file. Using the cancel button of the Open dialog cancels the Extract function.

Since the "Extract from File…" function can only be applied to the entire document no document dialog appears.

Note: If the security setting of the source document is set to "No Content Copying or Extraction, Disabled Accessibility", ImageEngine asks for the password to allow "Content Copying or Extraction".

If an invalid password is entered, ImageEngine shows an alert and stops the current function.

ImageEngine now shows a progress window. The function may be cancelled by pressing the key combination "Cmd" + "." or the "esc" key.

To keep the result of this function the user is now asked to confirm that he/she whishes to use this document. This alert window only appears if at least one image was found in the source document.

If the "Create Thumbnails" option is on, ImageEngine now creates the thumbnails for each page and shows the progress in a progress window. The function may be cancelled by pressing the key combination "Cmd" + "." or the "esc" key.

Further sequences depend on the settings for "Auto Save".

With "Auto Save" off, ImageEngine shows a Save dialog to let the user select where to save the file(s) generated.

With "Auto Save" on the file(s) are saved automatically in a newly created folder in the Auto Save destination folder.

Note: The sub folder will only be created if ImageEngine could create at least one file.

If the Creation Mode requires the creation of a PDF file, a progress window appears. This process cannot be interrupted.

Note: If the Creation Mode is set to "Create only" or "Create and View" and "Auto Save" is off, the user will be asked by a Save dialog to save the newly created PDF document as a file. If this dialog is cancelled, the new document will be neither displayed nor saved.

The result of the Extract function is a PDF document. Whether the document appears as front document of Adobe Acrobat or not, depends on the Creation Mode of the current settings.

Creation Mode: Use the radio buttons to set, how the PDF document will be generated.

Use "View only" to generate a temporary document. The document will be displayed in a new front window as soon as all steps of the generation are successfully accomplished. This temporary document can be saved later, e.g. using the menu "File" –> "Save As…"
Use "Create only" to generate a permanent document. The document will be saved as PDF file as soon as all steps of the generation are successfully accomplished, however it will not be displayed.
Use "Create and View" to generate a permanent document. The document will be saved as PDF file as soon as all steps of the generation are successfully accomplished, and will also be displayed in a new front window.
