  • Import AIF-FileCreates an ImageXObject from an ArtCom AIF file, put it in the currentpage resources and append code, that calls the image to the end of the contentstream. See also PDFImage
  • Set background opaque This should add a white opaque background for the current page. This function does a number of things at once. It adds a new separation colorspace with the name /All. this is registered in the current page as colorspace /PDFInquisitorAll. Then a rectangle is created with the size of the current MediaBox. This is added at the beginning of the content stream, set in the newly created colourspace, with a color value of one. This is white in all separations.
• Page The content of the page menu is also available as a pop-up menu in the page list.
  • Previous Page
  • Next Page
  • Add Page
  • Cut Page(s)
  • Copy Page(s)
  • Paste Page(s)
  • Show Thumbnails This function is only available from the Page List context menu. If turned on, the thumbnails for each page is displayed in the list. This of course only works, if thumbnails are available. If not a funny dummy thumbnail is displayed. There is a bug, that if a new file is loaded, the thumbnails of the old file persist.
  • remove unused resources Scans the content stream of all selected pages and those of the xobject contained and removes all defined resources that are not actually used.
  • rotate pages clockwise Rotate all selected pages clockwise
  • rotate pages counterclockwise Rotate all selected pages clockwise
  • Export pages to InquisitorExport.pdf All selected pages are exported to a new file InquisitorExport.pdf

• ColorsThe content of the colors menu is also available as a popup menu in the Spot Colors Panel
  • Load colorTableDict... Loads an I2K colorTableDict into the Editor of the Spot Color Panel.
  • Apply colorTableDict If a colorTableDict is loaded it can be applied to the current file.
• Object The content of the object menu is also available as a pop-up menu in the Object Editor
  • New.. Open a Dialog that lets you create a new object. You can select from a number of predefined objects, that I think can be useful.
  • Delete Object Calls the deleteObject Method for the currentObject, and tries to select a other object as current. No checks are done, if the object is referenced somewhere. Behavior is undefined, if no objects are left after deletion.
  • Check Function If the currently selected object is a function it outputs some sample values from the function on standard error of the application. For any dimension of the function domain, it trys 10 possible values and calculates the function result. This can take quite a while if the domain order is high like in a DeviceN tinttransform function.
  • View Image This is only enabled if the currently selected object is an image. If and only if the image can be decoded by the current filter implementation, an message Dialog opens, that shows the Image converted to RGB. It also displays some information about the image. Like the size and color space.
  • Edit Stream opens a dialog where the content of a stream can be edited. Useful for changing FormXObjects or type4 functions. But no luxury like undo or search so far. The filters applied to the stream will be the same.
  • Prev Select the object previous to the current.
  • Next Select the object with the next higher number.

Panels

• Pages More then one page can be selected. Some Operations in the Pages menu apply to all selected pages, like rotating and removing unused resources. Maybe there will be more actions in the future like setting pagesize and so on. By now only cutting and pasting of multiple pages is implented. The current page is underlined. See also PageList
• Document Tree View This is one instance of a Tree View that is explained below. It schows a view of the whole document as a tree. See also DocumentTreeView
• Content Editor It currently only shows the content of the current page. Showing other streams is impossible. You may edit the content stream. By typing CTRL-S is is possible to search for a certain string in the content stream, like a color-space name. Beside the usual cut and paste functionality, well known from other editors, there is a Emacs style way to mark large regions. You may set a mark at one position in the content stream by typing CTRL-M, scroll or search to another, and then type CTRL-P to mark the region between your current position and the mark. See also ContentEditor
• Spot Colors In this panel, you can see the spot colors used on the currently selected page. If available a dot with a representation of the spotcolor in the RGB colorspace is given. This panel is deactivated by default, since traversing the file takes a long time. Check the Activate this view Checkbox to activate it. See also SpotColorInfo
• Page Tree View This is another instance of a Tree View that is explained below. It shows a view of the current page as a tree. See also PageTreeView
• Object Editor Normally it shows the last object selected in one of the tree views, but you can also enter the object number in the object number panel in the top part of the Object Editor. The window is editable, if you select an indirect object, i.e. one with a object number. You may edit its textual representation. And as long as you don't mess the PDF syntax, the changes can be saved by Save or Save as..
  If you edit a stream object, you can only change the content of the stream dictionary, not the actual stream content.
  Since this panel does apply to objects, that may or may not be page related, it does not belong to the right page-level group. Maybe it should go into a group of its own, as soon as there are more object related panels. Or it could go into an extra window, that can be opened on demand, or always when the current object changes. See also ObjectEditor
• Stream as Hex Sometimes it is neseccary to view the content of a stream object in detail. Because a stream may be binary data it is shown in the same way, as the good old hexdump program used to show binary files. The Streamcontent is shown exactly when you selected an object from a TreeView or by selecting the object number in the ObjectEditor. There are three toggles on top of this panel:
  • isEncodedDisplays if there are any filters applied to the panel
  • showDecodedCan be turned on to show the decoded content, as far as decoding is possible and off to show the original content of the stream. Decoding displays only, but does not change the content of the file
  • dontShowDecoding or displaying the stream can be time consuming. if you are not interested in stream content, you may turn it of, while browsing through the file.
• FileHandler The File Handler not only masters the File Menu in the application window, it also controls the dialog for editing the info dictionary.

Tree Views

• Denotes a key in a dictionary or stream
• Denotes an unexpanded array
• Denotes an expanded array
• Denotes a closed dictionary or a stream
• Denotes a open dictionary or a stream
