is a global option that specifies settings for converting imported legacy notebooks.}})

OpenersNotesSection(Spacer1)Details

The typical usage is (RefLink[NotebookConvertSettings, paclet:ref/NotebookConvertSettings])->{(Subscript[opt, 1])->(Subscript[val, 1]),(Subscript[opt, 2])->(Subscript[val, 2]),…}.

The following options may be specified:

"GenerateBitmapCaches", "InputToStandardForm", "OutputToStandardForm" and "PreserveStyleSheet" are associated with the Notebook Convert dialog box, which appears when you open a notebook created using Version 2.

With the default setting "GenerateBitmapCaches"->(RefLink[False, paclet:ref/False]), no bitmap caches are generated, so any graphics present in the notebook will have to be rendered when they are first displayed while scrolling through the notebook.

With the setting "GenerateBitmapCaches"->(RefLink[True, paclet:ref/True]), each graphic in the notebook will be fully rendered during the conversion process and a bitmap cache stored in the new file. This can take a long time and consume a lot of memory for a large notebook containing many graphics cells. However, it allows the resulting notebook to be opened more quickly.

With the default setting "InputToStandardForm"->(RefLink[False, paclet:ref/False]), input cells present in a Version 2 notebook are not converted to (RefLink[StandardForm, paclet:ref/StandardForm]).

With the setting "InputToStandardForm"->(RefLink[True, paclet:ref/True]), input cells present in a Version 2 notebook are automatically converted to (RefLink[StandardForm, paclet:ref/StandardForm]) when the notebook is converted.

With the default setting "OutputToStandardForm"->(RefLink[False, paclet:ref/False]), output cells present in a Version 2 notebook are not converted to (RefLink[StandardForm, paclet:ref/StandardForm]).

With the setting "OutputToStandardForm"->(RefLink[True, paclet:ref/True]), output cells present in a Version 2 notebook are automatically converted to (RefLink[StandardForm, paclet:ref/StandardForm]) when the notebook is converted.

With the default setting "PreserveStyleSheet"->(RefLink[False, paclet:ref/False]), a Version 2 notebook is automatically assigned the default stylesheet when it is converted. All style information about the original notebook is therefore lost in the conversion.

With the setting "PreserveStyleSheet"->(RefLink[True, paclet:ref/True]), a private stylesheet is generated that replicates the styles used in the Version 2 notebook.

Because the default settings in the current version of the Wolfram System are fairly similar to those in Version 2, a notebook that did not define its own custom styles will look quite similar when converted with this option set to (RefLink[False, paclet:ref/False]). It is recommended that you elect not to preserve styles unless your notebook defines many custom styles; it is generally better to start with a fresh set of default styles.
