Pre-requisite: This SVG should be created with the 'Create Font Design Template' extension

The glyph bottom extent is derived from the reference horizontal guide(s)

Based on the option selected, the Right offset of the glyph will be either:

i) based on the right verical guide (if it exists) or bounding box or

ii) derived from the x coordinate of the last node of the main segment

Action can be one of the following:
|
||||||
|
- 'Render the text' renders the text from the Text input box
|
||||||
|
(Use \n in the input string to start a new line of text)
|
||||||
|
- 'Render text from file' renders the text from the file specified in the Text File input box
|
||||||
|
- 'Render font glyph table' displays all the available glyphs of the given font
|
||||||
|
along with the license information
|
||||||
|
|
||||||
|
If the 'Flow Text in Selected Boxes' option is selected, the text is fit into the selected rectangle objects with
|
||||||
|
specified margin and justification. The rectangles are filled in their z order. If a single word cannot fit within the
|
||||||
|
given width, it's broken into smaller components.
|
||||||
|
|
||||||
|
If there are errors, please ensure the font data files exist in the strokefontdata folder and

|
the font list is synchronized.</label>

Inkscape extension to render text with the stroke fonts.
|
||||||
|
|
||||||
|
The path data used to render the text is generated by the
|
||||||
|
'Generate Font Data' extension
|
||||||
|
|
||||||
|
The original concept is from Hershey Text extension (Copyright 2011, Windell H. Oskay),
|
||||||
|
that comes bundled with Inkscape
|
||||||
|
|
||||||
|
This tool extends it with a number of rendering options like flow in boxes,
|
||||||
|
text alignment and char & line spacing

|
||||||
|
|
||||||
|
Check the 'Generate Source Glyphs' option to create characters of the given size, stroke and fill opacity from the source font family; these can be used for tracing the stroke font glyphs.
|
||||||
|
You can optionally enter the first character or its unicode value in the 'First Glyph' text box. To input the unicode value, enter the 4 digit hex unicode in this field (e.g. 00C0 for À). Or you can directly enter just À. This character will be considered for rendering the font family glyphs in the template. If there is no entry in 'First Glyph' and if 'Generate Source Glyphs' is checked, the font family glyphs start from glyph corresponding to the character A.
|
||||||
|
Checking the 'Right Vertical Guides' options, creates an extra vertical guide at the right extreme of each glyph for manual setting of right offset.
|
||||||
|
In Space Width field enter the width of blank space between rendered words. This is generally 1/3 to 1/2 times the Font Size.</label>

PREAMBLE
|
||||||
|
The goals of the Open Font License (OFL) are to stimulate worldwide
|
||||||
|
development of collaborative font projects, to support the font creation
|
||||||
|
efforts of academic and linguistic communities, and to provide a free and
|
||||||
|
open framework in which fonts may be shared and improved in partnership
|
||||||
|
with others.
|
||||||
|
|
||||||
|
The OFL allows the licensed fonts to be used, studied, modified and
|
||||||
|
redistributed freely as long as they are not sold by themselves. The
|
||||||
|
fonts, including any derivative works, can be bundled, embedded,
|
||||||
|
redistributed and/or sold with any software provided that any reserved
|
||||||
|
names are not used by derivative works. The fonts and derivatives,
|
||||||
|
however, cannot be released under any other type of license. The
|
||||||
|
requirement for fonts to remain under this license does not apply
|
||||||
|
to any document created using the fonts or their derivatives.
|
||||||
|
|
||||||
|
