### The tioga kernel¶ ↑

This is the reference document for using of the tioga kernel to create figures and plots using Ruby, PDF, and TeX. Please understand that this is more like a dictionary than a textbook.

It is written assuming that you’ve already familiarized yourself with how things work to the level covered in the `Tutorial`.

Without that background, much of the following may be incomprehensible.

Page Layout and System Control

- `Page_Frame_Bounds`

- `Figures_and_Plots`

- `Executive`

Graphics

- `ColorConstants`

- `Creating_Paths`

- `Using_Paths`

- `Strokes` (Lines and Curves)

- `Rectangles`

- `Arcs_and_Circles`

- `Special_Paths` (Contours, Splines, Steps, Arrows, Error Bars)

- `Colormaps`

- `Images` (JPEGs and Sampled Data)

- `Shading` (Radial and Axial Blends)

- `Transparency`

- `FigureConstants`

Text

- `MarkerConstants`

- `Markers`

- `TeX_Text`

Extras for Plots

- `Titles_and_Labels`

- `X_and_Y_Axes`

- `Legends`

- `Colorbars`

Facilities for Storing Numeric Data

- `Dobjects::Dvector`

- `Dobjects::Dtable`

For more information on PDF, consult the Adode PDF Reference document.

It’s a huge collection of details (over 1000 pages at last count), and I’ve borrowed extensively from it in some of the following descriptions of methods that map directly to PDF operations.
