| How to install the font: | ||
| ======================== | ||
| ## Linux(Ubuntu): | ||
| * Open font with Font Manager and install on System-level | ||
|
|
||
| ## Microsoft Windows: | ||
| * Double-click on font file and install | ||
|
|
||
| ## Apple/Mac: | ||
| * Unknown | ||
|
|
||
|
|
||
| How to use the font: | ||
| ==================== | ||
| * In text-processing program, insert "Special Character" | ||
| * Choose required symbols (see Examples.pdf or Examples.odt for ideas) | ||
| * Place and align according to demands | ||
| * If e.g., a closed circular multiline plasmidmap is required, close vertical gaps adjusting line spacing by | ||
| * clicking on menu: "Format" / "Paragraph" and | ||
| * select "Proportional" of ~"92%" at "Line Spacing" | ||
| * After export to PDF, document can be imported to e.g., Inkscape via Poppler/Cairo import and used as path element | ||
|
|
||
| Principles that were used in designing the font: | ||
| ================================================ | ||
| ## Inkscape: | ||
| * Import the svg files from the SBOL Github Rep | ||
| * Scale them up to 4096px width | ||
| * Create a layer for each glyph in Inkscape via Menu:Extensions/Typography/Add Glyph Layer | ||
| * Add DNA baseline if required according to specification | ||
| * Ungroup if required | ||
| * Convert from strokes to paths | ||
| * Combine paths | ||
| * Center & Align | ||
| * Save all layers as one svg | ||
|
|
||
| ## FontForge: | ||
| * Open/Import above svg through FontForge or manually (ctrl+c & ctrl+v) | ||
| * Setup font information | ||
| * Correct wrong direction | ||
| * Add missing extremas | ||
| * Correct non-integral coordinates | ||
| * Correct intersecting paths | ||
| * Duplicate points that count as intersections are very common. | ||
| * Generate Font | ||
|
|
||
| Principles that were used in testing the font: | ||
| ============================================== | ||
| Font has been tested by recreating Examples.odt and Examples.pdf in LibreOffice Writer Version: 5.4.6.2: | ||
| * in Kubuntu 17.10 Artful Aardvark and 18.04 Bionic Beaver | ||
| * On menu click: "insert" / "special character" | ||
| * Choose up to 16 characters per insert (can be repeated) | ||
| * Place and align as desired | ||
| * If required, close vertical gaps adjusting line spacing by | ||
| * clicking on menu: "Format" / "Paragraph" and | ||
| * select "Proportional" of ~"92%" at "Line Spacing" | ||
| * Click "File" / "Save as" "Example.odt" | ||
| * Click "File" / "Export as PDF" "Example.pdf" | ||
|
|
||
| How to update the font when new symbols are added: | ||
| ================================================== | ||
| * Prepare new symbol in e.g., Inkscape | ||
| * Open sfd file with e.g., FontForge | ||
| * Vacate dedicated unicode allocation by moving existing symbols up the table (ctrl+x & ctrl+v) | ||
| * Paste new symbol into dedicated, now vacated slot | ||
| * Perform validation as above (missing extrema, non-integral coordinates, intersections and wrong direction) | ||
| * If no errors are shown during validation, generate font | ||
|
|
||
| How to test that an update has been completed correctly: | ||
| ======================================================== | ||
| * Recreate Example.odt and Example.pdf now including the new symbol |
