6.6.6 Advanced Box Options

Box Comparisons

When an image appears at the very start an article in a series of articles, it can present a particular problem for basic box ordering. The extraction system can place the image at the end of the preceding article, if your content-model allows it.

A related problem is that, if your content model allows an article to start with an image, this means any image in the body of an article could potentially trigger a new article.

Both of these scenarios would lead to undesirable results in your XML.

By comparing the middle of images, rather than the top-left corner, images will be extracted later than identically aligned text boxes, and avoid these pitfalls. From Atomik Xport 4.3, this is the default behaviour of the extraction system. You can set this comparison point to ‘middle’ or ‘top-left’, for images, in the Box comparisons section of the Advanced Box Options.

Follow Text Chains

The default behaviour of Atomik Xport is to follow threaded (chained) boxes, and extract their entire text thread as if the text were contained in the same box. This avoids splitting paragraphs inadvertently. However, there may be situations where you wish to treat every box containing threaded text as if it were separate, and instead compare it with other boxes on the page. Unchecking the ‘Follow text chains’ checkbox will allow your documents to be processed in this way.

Follow Text Chains on to the Pasteboard

The “Follow Text Chains on to the Pasteboard” setting is only available if “Follow Text Chains” is enabled.

Normally Atomik Xport does not extract the content of any box on the pasteboard unless it overlaps a layout page.

Checking this option will ensure that text boxes which appear on the pasteboard are considered for extraction if they are threaded (chained) to from text boxes on the page.

For example, if a box on the pasteboard contains the overflow from a text chain on the layout, then enabling this setting will cause its content to be considered for extraction.

Box Ordering authored using Atomik Tools overrides

The “Box Ordering authored using Atomik Tools overrides Ruleset options” setting is recommended. The separate Atomik Tools plugin allows users to set up document-specific box ordering settings, to override these settings on a spread-by-spread basis or even to record a custom box ordering. Normally these Atomik Tools settings will override box ordering settings from the ruleset, but if you uncheck this setting then the Ruleset box ordering settings will be used instead.

Insert Floating Images in to main Text Flow

This is an advanced option where Atomik Xport attempts to insert images which are to the left of, above, below or to the right of the main text flow, into the main text flow.

The “main text flow” is defined as the largest text box on the page which is part of a text chain. If no text box on the page is part of a text chain then Atomik Xport will consider there is no main text flow and this option will have no effect.

This option is not concerned with images that are overlapping text boxes (that is handled by the “Insert Overlapping Boxes” option) but only with images that are not overlapping. Images which Atomik Xport inserts as a result of this option will always be inserted at the end of a paragraph.

For example, in the page layout below, if the “Insert Floating Images in to main Text Flow” option is checked, then the rabbit image will be inserted at the end of the paragraph that begins “The rabbit-hole went straight on like a tunnel“, in other words after the paragraph that starts at the bottom of this page. Whereas, if the option were not checked, then the image would be extracted after the entire main text flow, which for books would typically be at the end of a chapter of text.

Insert Floating Text Boxes in to main Text Flow

This is an advanced option where Atomik Xport attempts to insert text boxes which are to the left of, above, below or to the right of the main text flow, into the main text flow.

It is similar to the “Insert Floating Images in to main Text Flow” option but for floating, non-chained, text boxes rather than images.

The “main text flow” is defined as the largest text box on the page which is part of a text chain. If no text box on the page is part of a text chain then the system will consider there is no main text flow and this option will have no effect.

This option is not concerned with text boxes that are overlapping text boxes (that is handled by the “Insert Overlapping Boxes” option) but only with images that are not overlapping. Text boxes which Atomik Xport inserts as a result of this option will always be inserted at the end of a paragraph.
