Tool
GEMINI_API_KEY=$(grep GEMINI_API_KEY .env | cut -d= -f2) \
node tools/generate-image.mjs "<prompt>" [--out <path>] [--aspect <ratio>] [--model <name>] [--count <n>] [--ref <image>]
Modely
| Model | Poznámka |
|---|
gemini-3-pro-image-preview | Default — nejlepší kvalita |
gemini-3.1-flash-image-preview | Rychlejší |

Aspect ratios
1:1 | 16:9 | 9:16 | 4:3 | 3:4
Asset Pipeline (POVINNÝ WORKFLOW)
Krok 1: Generuj přes Gemini
Pro sprite sheet (více assetů najednou):
node tools/generate-image.mjs \
"Pixel art sprite sheet of 8 breakout bricks in horizontal row, evenly spaced on pure black background. Colors: pink, red, orange, gold, green, cyan, blue, purple. Each brick ~2.5:1 aspect ratio, neon style, dark outline. No text." \
--out public/assets/games/breakout/bricks-sheet.png \
--aspect 4:3
