Check whether a ChatGPT account is logged in for image generation.

Generate image(s) from a text prompt at the given aspect ratio (16:9, 1:1, 3:4, 9:16, or WxH). Returns saved PNG file paths.

When enhance is True (default), the prompt is auto-expanded via the ChatGPT
text path before drawing. style='slide' = clean editorial slide (light cream,
one accent, hero visual); style='fintech' = premium light-blue dashboard look
(glass cards, blue icon badges, optional robot + charts). Both auto-complete
content into a full, information-rich slide (label + 2-line description per
point, sparse input expanded). style='auto' is the general default.

Assemble existing image files into a full-bleed PowerPoint deck.

Generate one image per prompt then assemble them into a PPTX deck.

Each prompt should be the CONTENT of one slide. style='slide' (default here) applies a clean editorial presentation design (light, restrained accent, one hero visual, short labels, takeaway banner) — pass raw slide content and the enhancer designs it. Set enhance=False to send prompts verbatim.

Build a branded slide deck: auto-detect brand colors from the logo, generate slides in those colors, composite the original logo onto each slide, assemble PPTX.

Generate a deck matching a reference design image's style and colors (content not copied).
