Interface icons (high-res)

Generated on 2026-11-07 with fal-ai/nano-banana-pro (resolution: 2K, one image per sheet, aspect_ratio: 21:9 for the 5-column sheets, 16:9 for the spells). batch.py holds the prompts: the shared text below followed by the numbered icon descriptions.

A sheet of game icons for a dark-fantasy dungeon strategy game, arranged in a grid of {cols} columns and {rows} rows, every icon centred in its own equal square cell and filling about 80 percent of it, all icons the same size and in the same style: hand-painted pixel art, chunky clear shapes, crisp edges, a dark near-black outline, rich but slightly muted colours, readable at small size, light from the upper left. The background is a completely flat pure magenta (#FF00FF) everywhere, also between the icons - no frames, no grid lines, no cell borders, no text, no labels, no numbers.

Processing

tools/cut_icons.py <sheet>-raw.png <sheet> --grid 2x5 (spells --grid 2x4) keys out only nearly pure magenta (violet glows stay), crops every icon, centres it in a square and scales it to 64x64 and 128x128 with hard alpha. The strips go to assets/textures/icons/; the game puts them into the high-res atlases' icon cells (HD_ICONS in src/gfx.rs).
