22.6.3 Indenting images

By default, Mif2Go indents all non-inline graphics to match the indent used in your FrameMaker document. Graphics (and also tables) are indented in HTML output using a technique invented by Chuck Musciano:

http://www.webreview.com/tag/1999/05_14_99.shtml

This technique consists of placing, at the start of the line that contains the graphic, a one-pixel transparent GIF image, 1p.gif, with a width attribute that produces the required indent in pixels. See §27.1.5 Modifying Mif2Go-supplied macro definitions.

To eliminate use of the spacer graphic:

[HTMLOptions]

; UseSpacers = Yes (HTML default, use to position tables and graphics)

; or No (XML default)

UseSpacers = No

When UseSpacers=No, the spacer image is omitted from output. Graphics are not indented, nor are tables (see §23.5.1 Indenting tables).

Spacer alt attribute

The spacer graphic must have an alt attribute for W3C validation. The default value for the spacer alt attribute is [spacer]; you can change this default:

[HTMLOptions]

; SpacerAlt = text to use for alt attribute for spacer,

;  default [spacer]

SpacerAlt = [spacer]

Left indent

You can specify a custom indent for a single graphic or a graphics group; for example:

[GraphIndents]

; Graphic ID = number of pixels to indent using PixelSpacerImage

;  zero prevents indent, -1 is autoindent (default action)

schematic = 30

Right indent

A similar method creates a space to the right of the image, except that the height attribute of the spacer is set to match the height attribute of the image. This is useful for run-in graphics, and for other floating types. For example:

[GraphRightSpacers]

; Graphic ID = number of pixels space on right using PixelSpacerImage

ch00b5d3 = 45

No indent

If you do not want any graphics indented, use a wildcard setting, as follows:

[GraphIndents]

* = 0

See §4.1.6 Using wildcards in configuration settings.
