iCalamus offers to place content from other programs in a
document. In general, you will add e.g. texts, images or graphics in
documents using the Import and Place functions. When you want to
change these contents afterwards, you may do so in iCalamus but meet
different difficulties then. Basically, you can change text directly
in iCalamus, but for images and graphics and even more special objects
iCalamus doesn't offer many tools right now. So you will usually start
the external program in which you have created such an object, then
change the object, save it and place it in iCalamus once more.
Right now there are some applications which support the LinkBack technology and can be used much easier.
A link is a reference to another place. A backlink is a
reference back to the source of an object. The LinkBack technology
offers all necessary steps to let a program like iCalamus recognize
when you have placed objects from a LinkBack supporting program in a
document. When you select such an object, iCalamus knows
that
the object originates from program XY and iCalamus can call this
program for you, handle over the object to this program for editing
and update the object in the document immediately after you have saved
changes to the object.
When you have created a bar code with Barcody, our Bar Code Generator program for OS X, and have placed it in a iCalamus document, iCalamus knows that it originates from Barcody.
When you have selected the bar code in the document, the otherwise
neutral menu entry Edit LinkBack Item
changes into a
program-specific entry, here e.g. into Edit in Barcody
.
When you choose this menu entry, iCalamus automatically starts Barcody and transfers the selected objert to Barcody for editing. Now you can change the bar code parameters without excitement in Barcody.
After you have saved the bar code, it will be automatically updated in the iCalamus document.
