6.8.1. Error Handling

Since with nearly all functions of ImageEngine errors may occur an error handling function has been included.

There are some situations, where only a single message is necessary, but in some other situations, multiple errors may occur.

For example imagine the following situation: The user tries to export images from a large PDF document and the destination disk has only a small amount of free space. The disk (dependent from the number and size of the images) will be filled by a small number of files so it is impossible to store all images.

The user can decide which kind of error handling he/she prefers.

Use "Break" to get an alert with every error. This alert allows to continue or to cancel the current operation.
Use "Add to List" to add all error messages to a list which is presented as a PDF document when the function is completed.
Use "Ignore" to avoid any error messages.

In every case, the number of errors is shown in the progress bar display. Also, in every case the user can cancel any operation of ImageEngine by pressing the key combination "Cmd" + "." or the "esc" key.

6.8.1. Page Layout

Some functions of ImageEngine create PDF documents, e.g. to list the error messages. Also the Inspect function creates a PDF document. The Dimensions pop-up menu allows to choose between A4 and US Letter page sizes for these PDF documents.
