Setting Text

Two justified columns with automatic hyphenation, old-style figures, a drop cap and a pull quote — the everyday machinery of a well-made page.

OpenType Features

Each row shows the same text with a feature off, then on. The glyphs differ; the underlying characters do not.

One variable font, nine weights

System UI · a single variable font file supplies every weight; the PDF embeds each instance as its own subset.

Script faces

Expressive Type

Effects that become transparency groups, soft masks, clipping paths and transformed text objects once they reach PDF.

Text on a curve

SVG textPath · each glyph is positioned and rotated individually along a cubic Bézier, filled with a gradient.

Hierarchy through contrast

Scripts of the World

A short greeting — roughly, “every letter deserves a good home” — in writing systems that need bidirectional layout, contextual shaping, reordering and vertical setting.

Mixed direction in one line

The word كتاب means “book”, and ספר does too — the bidi algorithm keeps each run in its own direction while the sentence stays left-to-right, even across numbers like ٣٤٥ and 345.

Colour emoji

Noto Color Emoji (OFL) · colour bitmap glyphs that Chrome places into the PDF as images.

Mathematics

Equations written in MathML Core and laid out by the browser: stretchy delimiters, radicals, large operators, scripts and matrices.

Inline mathematics

A PDF page maps user space to device space with a matrix $\left[abcdef\right]$, so a point $(x,y)$ lands at $(ax+cy+e,bx+dy+f)$. With one point equal to $\frac{1}{72}$ inch, a Letter page measures $612\times 792$ points, and a 300 dpi raster of it holds roughly $8.4\times {10}^6$ pixels.

Symbols and arrows

Vector Graphics

Nine small plates, each exercising one piece of the PDF imaging model.

Layered waves · five-stop shading, 50% overlay in multiply mode, dashed stroke over the top.

Data & Tables

Charts drawn as SVG and a striped table. All figures are illustrative sample data, not measurements.

Where each PDF feature lives in this file

Code & Images

A monospaced listing with syntax colouring, and the raster that it describes.

1// Escape-time rendering of Seahorse Valley into an RGB buffer.

10               z = (z.0 * z.0 - z.1 * z.1 + c.0, 2.0 * z.0 * z.1 + c.1);

A generated raster

The image at left is computed by the xtask each time the showcase is built, encoded as PNG and handed to Chrome, which embeds it as an image XObject. Nothing is downloaded and no third-party artwork is involved, so the file stays reproducible and free to redistribute.

At 60 dpi the fractal edge looks smooth; zoom in and the individual pixels appear, a useful check that the viewer switches from filtered to nearest-neighbour sampling at the right moment.
