Scanline Loading
================

20 hologram loading and waiting indicators for dark interfaces — ocean black
with ember orange accents. SVG plus transparent PNG at 1x, 2x and 4x.

Scanline Loading is a set of 20 loading and waiting indicators drawn in the
hologram style, where a thin trace carries a wide halo, and most of the frame
is empty space. It contains an eight-frame spinner, a three-frame dot cycle, a
loading bar frame with four fill steps, an indeterminate striped bar, two
skeleton text lines and a skeleton image block.

The loading screen is the screen a player looks at longest and the one nobody
makes art for. It is also the one place where a bar means something different
from everywhere else: a resource bar shows a value, a loading bar shows a
process, and using the same sprite for both is how a health bar ends up on a
loading screen.

The halo is a stack of strokes at falling opacity rather than a blur filter —
a filter is applied differently by some SVG rasterisers and smears at 4x. The
trace is deliberately thin: a projected interface reads as light, and a heavy
line reads as paint.

Inside that style this is the Scanline reading of it: a dark interface on a
ocean black palette with ember orange accents, built around a single bordered
frame, chamfered buttons at 120x34, hollow-cored bars divided into 24
segments, and two-tone icons on a 16px grid. Those measurements are why two
families can share an art style without being interchangeable: the style
decides how an edge is drawn, the numbers decide what the interface is for.

The spinner ships as eight frames rather than one sprite to rotate. Rotation
exists in every engine, but the number of frames does not — and in a pixel
style a spinner that rotates smoothly is wrong, it should step. An eight-frame
atlas is correct in both cases and works everywhere. The skeleton placeholders
are here for the same reason the spinner is: an empty screen while content
loads reads as broken, and a grey block that has the shape of the thing
arriving reads as waiting.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x,
so you can drop the PNGs straight into an engine or open the vector and change
a colour. Built to the same measurements as the rest of the Scanline family,
which means this kit and the Scanline panel kit line up without either being
resized. A good fit for sci-fi projections, scanners and near-future overlays.

HOW TO USE

  - Play the spinner frames in order at about 12 frames per second; slower
    reads as stuck and faster reads as noise.
  - Use the indeterminate bar when you cannot report a percentage, and switch
    to the stepped fills the moment you can — a fake percentage is worse than
    none.
  - Lay the skeleton line and block in the same positions as the real content
    so nothing jumps when it arrives.
  - Keep the loading bar in the accent colour rather than a resource colour; a
    loading bar that looks like a health bar is read as one.
