                                                                                                                                                                                                  <p>
Some <pretext/> objects are relatively indivisable and are used as components of other structures.  We call them <term>atomic</term>, even if the term is not perfect.  A good example is <tag>image</tag> (next, <xref ref="atomic-image"/>).  This section is arranged according to these objects and tests the various ways they can be employed.
                                                                                                                                                                                                  </p>

                                                                                                                                                                                                  <p>
We frequently include some nonsense text inside short intervening paragraphs to test spacing and establish margins.

 For <latex/>, in some circumstances it is desirable to print the image on the next line, but backed up by some amount. This <q>top-aligns</q> the image with a number of some sort off to the left. The following are tests for this behavior. Here is a list.

Videos can be realized in many forms, and can come from a variety of sources.  See <xref ref="section-video" text="type-global"/> for tests of some of that variety.  Here we are testing placement within surroundings and testing the schema for location.  But we do have two videos in each test, one provided as a local file and one embedded from a service.

Programs can be realized in many forms, and can come from a variety of sources.  See <xref ref="section-video" text="type-global"/> for tests of some of that variety.  Here we are testing placement within surroundings and testing the schema for location.  But we do have two videos in each test, one provided as a local file and one embedded from a service.

A <tag>tabular</tag> realized by <latex/> for PDF/print will normally be as wide as necessary to hold the content, without word-wrapping the content of any cell that is not explicitly authored that way.  This is the most rigid of the content types we call <q>planar.</q>  So for <pretext/> output as <latex/>, when you explicitly constrain the width to be less than the <q>natural width</q> (including use as a panel of a <tag>sidebyside</tag>, or even setting margins) the table will be scaled <em>down</em> in width, which can result in an apparent font size very much smaller than that of the surrounding text.  Note that we do not ever scale a tabular up to be wider with a larger font size.  Note also that if there is no attempt to control the space for the table (no layout control, not in a <tag>sidebyside</tag>) then no scaling is attempted at all and the table may be wider than the text and protrude into the right margin.  For more, see the three examples at: <xref ref="natural-too-wide" text="type-global"/> , <xref ref="scale-down-auto" text="type-global"/>, <xref ref="scale-down-100" text="type-global"/>.  Generally, much of the commentary and testing here is about <latex/>/PDF/print.  While for <init>HTML</init> output the cells will usually automatically word-wrap to fit in the available space, without adjusting the font size.  Some might like this behavior and some might not.

In amongst a run of paragraphs (or similar) a <tag>tabular</tag> can be placed with layout control.  For <latex/> output, this will scale the table to fit within the explicit, or implicit, width.  This can result in obvious differences in the apparent font size.  We first have a <attr>width</attr> that is experimentally similar to the natural width, with asymetric margins.  Then a narrow width, and a wide width, as an illustration.

The next table is purposely much too wide.  In <xref ref="natural-too-wide" text="type-global"/> we make no attempt to control the width, and so it will extend into the margins.  In <xref ref="scale-down-auto" text="type-global"/> we have simple added the attribute <c>width="auto"</c>.  This attempt to use layout control will cause an automatic reduction in width and a smaller apparent font size.  Adjusting margins providing an explicit percentage width, or placing the tabular as a panel of <tag>sidebyside</tag> will have the same effect.  In <xref ref="scale-down-100" text="type-global"/> we have set the width explicity to 100% and so it should be identical to the automatic width case just prior.

Some PreTeXt objects are relatively indivisable and are used as components of other structures. We call them atomic, even if the term is not perfect. A good example is <image> (next, 31.1). This section is arranged according to these objects and tests the various ways they can be employed.
We frequently include some nonsense text inside short intervening paragraphs to test spacing and establish margins.

An <image> can be placed in five different ways:
  1. all by itself, as a peer of <p> typically, with layout control,
  2. inside a <figure>, earning a number and caption,
  3. inside a <sidebyside>, with size and layout configured,
  4. inside a <figure> inside a <sidebyside>, with size and layout configured, with a number and caption, and
  5. inside a <figure> inside a <sidebyside> inside a <figure>, with size and layout configured, with a number and caption, but now sub-numbered ((a), (b), (c),โ€ฆ).
Examples of each, and more.
All by itsef, with no layout specified, so showing the default size and placement. Vivamus in congue massa. Morbi condimentum ac magna at accumsan. Vestibulum ac augue eu lorem semper gravida.
Width set at 40%, so equal margins and thus centered. Aenean faucibus augue tellus, et sollicitudin tortor finibus non. Maecenas semper dolor quis diam placerat, iaculis sollicitudin augue finibus. Vestibulum facilisis ligula lectus, ac tristique nisl aliquet non.
Asymmetric margins of 20% and 40% given, implying 40% width, equal to previous instance. Vivamus suscipit diam eget mi cursus viverra.
As a plain component of a <sidebyside>. Widths here are 20% and 30%, margins and gaps are automatic, default alignment on top edges. Nulla pharetra imperdiet elit, in sodales nibh blandit ultricies. Maecenas efficitur ac felis ut pharetra.
Inside a <figure> with no adjustments, so default behavior. Note how a <figure> occupies the entire width of the page, so then does the caption.

For , in some circumstances it is desirable to print the image on the next line, but backed up by some amount. This โ€œtop-alignsโ€ the image with a number of some sort off to the left. The following are tests for this behavior. Here is a list.
A rotation="n" attribute applied to a bare image will rotate the image by nยฐ. The vertical space adjusts to accomodate the rotated image in the latex version but not in the html version.

An <video> can be placed in five different ways:
  1. all by itself, as a peer of <p> typically, with layout control,
  2. inside a <figure>, earning a number and caption,
  3. inside a <sidebyside>, with size and layout configured,
  4. inside a <figure> inside a <sidebyside>, with size and layout configured, with a number and caption, and
  5. inside a <figure> inside a <sidebyside> inside a <figure>, with size and layout configured, with a number and caption, but now sub-numbered ((a), (b), (c),โ€ฆ).
Examples of each, and more.
Videos can be realized in many forms, and can come from a variety of sources. See Sectionย 20 for tests of some of that variety. Here we are testing placement within surroundings and testing the schema for location. But we do have two videos in each test, one provided as a local file and one embedded from a service.
All by itsef, with no layout specified, so showing the default size and placement. Vivamus in congue massa. Morbi condimentum ac magna at accumsan. Vestibulum ac augue eu lorem semper gravida.
Vestibulum facilisis ligula lectus, ac tristique nisl aliquet non. Quisque ornare felis arcu. Vivamus suscipit diam eget mi cursus viverra.
Width set at 40%, so equal margins and thus centered. Aenean faucibus augue tellus, et sollicitudin tortor finibus non. Maecenas semper dolor quis diam placerat, iaculis sollicitudin augue finibus. Vestibulum facilisis ligula lectus, ac tristique nisl aliquet non.
Vestibulum facilisis ligula lectus, ac tristique nisl aliquet non. Quisque ornare felis arcu. Vivamus suscipit diam eget mi cursus viverra.
This next video should start on a new page if the distribution publication file is in use.
Asymmetric margins of 20% and 40% given, implying 40% width, equal to previous instance. Vivamus suscipit diam eget mi cursus viverra.
Vestibulum facilisis ligula lectus, ac tristique nisl aliquet non. Quisque ornare felis arcu. Vivamus suscipit diam eget mi cursus viverra.
As a plain component of a <sidebyside>. Widths here are 20% and 30%, margins and gaps are automatic, default alignment on top edges. Nulla pharetra imperdiet elit, in sodales nibh blandit ultricies. Maecenas efficitur ac felis ut pharetra.
Inside a <figure> with no adjustments, so default behavior. Note how a <figure> occupies the entire width of the page, so then does the caption.

Programs can be realized in many forms, and can come from a variety of sources.  See <xref ref="section-video" text="type-global"/> for tests of some of that variety.  Here we are testing placement within surroundings and testing the schema for location.  But we do have two videos in each test, one provided as a local file and one embedded from a service.

A <program> and/or <console> can be placed in at least six different ways:
  1. all by itself, as a peer of <p> typically, with layout control
  2. inside a <listing>, earning a number and caption, with layout control
  3. inside a <sidebyside>, with size and layout configured
  4. inside a <sidebyside>, with size and layout configured, and inside a <figure>
  5. inside a <sidebyside>, with size and layout configured, with each inside a <listing>, earning different numbers
  6. inside a <figure> inside a <sidebyside> inside a <listing>, with size and layout configured, with a number and title, but now sub-numbered ((a), (b), (c),โ€ฆ).
Examples of each, and more.
Programs can be realized in many forms, and can come from a variety of sources. See Sectionย 20 for tests of some of that variety. Here we are testing placement within surroundings and testing the schema for location. But we do have two videos in each test, one provided as a local file and one embedded from a service.
All by itsef, with no layout specified, so showing the default size and placement. Vivamus in congue massa. Morbi condimentum ac magna at accumsan. Vestibulum ac augue eu lorem semper gravida.

A <tag>tabular</tag> realized by <latex/> for PDF/print will normally be as wide as necessary to hold the content, without word-wrapping the content of any cell that is not explicitly authored that way.  This is the most rigid of the content types we call <q>planar.</q>  So for <pretext/> output as <latex/>, when you explicitly constrain the width to be less than the <q>natural width</q> (including use as a panel of a <tag>sidebyside</tag>, or even setting margins) the table will be scaled <em>down</em> in width, which can result in an apparent font size very much smaller than that of the surrounding text.  Note that we do not ever scale a tabular up to be wider with a larger font size.  Note also that if there is no attempt to control the space for the table (no layout control, not in a <tag>sidebyside</tag>) then no scaling is attempted at all and the table may be wider than the text and protrude into the right margin.  For more, see the three examples at: <xref ref="natural-too-wide" text="type-global"/> , <xref ref="scale-down-auto" text="type-global"/>, <xref ref="scale-down-100" text="type-global"/>.  Generally, much of the commentary and testing here is about <latex/>/PDF/print.  While for <init>HTML</init> output the cells will usually automatically word-wrap to fit in the available space, without adjusting the font size.  Some might like this behavior and some might not.

In amongst a run of paragraphs (or similar) a <tag>tabular</tag> can be placed with layout control.  For <latex/> output, this will scale the table to fit within the explicit, or implicit, width.  This can result in obvious differences in the apparent font size.  We first have a <attr>width</attr> that is experimentally similar to the natural width, with asymetric margins.  Then a narrow width, and a wide width, as an illustration.

The next table is purposely much too wide.  In <xref ref="natural-too-wide" text="type-global"/> we make no attempt to control the width, and so it will extend into the margins.  In <xref ref="scale-down-auto" text="type-global"/> we have simple added the attribute <c>width="auto"</c>.  This attempt to use layout control will cause an automatic reduction in width and a smaller apparent font size.  Adjusting margins providing an explicit percentage width, or placing the tabular as a panel of <tag>sidebyside</tag> will have the same effect.  In <xref ref="scale-down-100" text="type-global"/> we have set the width explicity to 100% and so it should be identical to the automatic width case just prior.

A <tabular> can be placed in six different ways:
  1. all by itself, as a peer of <p> typically, with no layout control and hence with a โ€œnatural width,โ€ and centered
  2. all by itself, as a peer of <p> typically, with explicit layout control,
  3. inside a <table>, earning a number and title,
  4. inside a <sidebyside>, with size and layout configured,
  5. inside a <table> inside a <sidebyside>, with size and layout configured, with a number and title, and
  6. inside a <table> inside a <sidebyside> inside a <figure>, with size and layout configured, with a number and title, but now sub-numbered ((a), (b), (c),โ€ฆ).
Examples of each, and more.
A <tabular> realized by for PDF/print will normally be as wide as necessary to hold the content, without word-wrapping the content of any cell that is not explicitly authored that way. This is the most rigid of the content types we call โ€œplanar.โ€ So for PreTeXt output as , when you explicitly constrain the width to be less than the โ€œnatural widthโ€ (including use as a panel of a <sidebyside>, or even setting margins) the table will be scaled down in width, which can result in an apparent font size very much smaller than that of the surrounding text. Note that we do not ever scale a tabular up to be wider with a larger font size. Note also that if there is no attempt to control the space for the table (no layout control, not in a <sidebyside>) then no scaling is attempted at all and the table may be wider than the text and protrude into the right margin. For more, see the three examples at: Tableย 31.29 , Tableย 31.30, Tableย 31.31. Generally, much of the commentary and testing here is about /PDF/print. While for HTML output the cells will usually automatically word-wrap to fit in the available space, without adjusting the font size. Some might like this behavior and some might not.
Data in a table form can be placed in amongst a series of paragraphs. With no layout control, it will occupy its โ€œnatural widthโ€ and be centered.

The same effect can be had by specifying that the @width attribute have the value auto, but do not specify any @margins. We test multiple footnotes in a <tabular>, not included in a <table>.

In amongst a run of paragraphs (or similar) a <tabular> can be placed with layout control. For output, this will scale the table to fit within the explicit, or implicit, width. This can result in obvious differences in the apparent font size. We first have a @width that is experimentally similar to the natural width, with asymetric margins. Then a narrow width, and a wide width, as an illustration.

The next table is purposely much too wide. In Tableย 31.29 we make no attempt to control the width, and so it will extend into the margins. In Tableย 31.30 we have simple added the attribute width="auto". This attempt to use layout control will cause an automatic reduction in width and a smaller apparent font size. Adjusting margins providing an explicit percentage width, or placing the tabular as a panel of <sidebyside> will have the same effect. In Tableย 31.31 we have set the width explicity to 100% and so it should be identical to the automatic width case just prior.
