Illustrae Alternative: FigEditor for Scientific Figures You Keep Editing

A bacteriophage illustration can combine a richly shaded body with simple editable labels. If a reviewer later changes “tail fibres” to “receptor-binding fibres”, the entire organism should not need to be redrawn. This mixed-document case is a useful test of an Illustrae alternative.

Decide which parts need object editing

The Illustrae homepage FAQ describes PNG export and limits SVG export to simple elements, diagrams, text and labels that do not use its generated images. That is a concrete distinction to preserve in a comparison, rather than claiming every generated organism becomes vector geometry.

For this exercise, treat the organism as an illustrative background and keep labels and leader lines separate. The anatomy must be checked against an authorised source appropriate to the actual organism; the following prompt is only a schematic exercise.

Draw a simplified bacteriophage teaching illustration with a head, a tail and a baseplate. Leave generous white space around it for labels. Do not add text, dimensions, species names or a claim of structural accuracy. Use a plain background and consistent lighting.

Add a small, controlled annotation layer

Element	Intended representation	Revision test
Organism illustration	Reviewed raster background	Keep pixels unchanged during text edits
Head/Tail/Baseplate labels	Separate text objects	Retype one label
Three leader lines	Separate paths	Move one endpoint
Scale information	Only if scientifically supported	Verify against the source, not the artwork

Do not add a scale bar to a conceptual generated organism merely to make it look publication-ready. A scale bar asserts a relationship to physical size.

Test an actual reviewer request

Save version A. In version B, rename one label and move it 5 mm to avoid overlap. Keep the organism, other labels and leader-line endpoints unchanged. Reopen both exported versions and compare them.

If the organism changes during this edit, you used a generative revision rather than an object-only change. That may be acceptable for concept exploration, but it is different from maintaining a reviewed final illustration.

Avoid unnecessary tracing

Shaded biological artwork can produce many tiny regions when traced. Vectorising every shadow may increase file size and make repair harder without improving the scientific explanation. Consider a mixed master: embedded illustration plus editable annotation objects.

In FigEditor, inspect any conversion result in the SVG editor and proofread OCR labels. A larger output setting cannot create anatomical information that the original did not contain.

Deliver the right evidence

Keep the visual source, prompt, reviewed background, annotation master and final copy. State which parts remain raster. Check reference permissions and the target publisher’s current AI-image policy. The best alternative is the one that preserves the required edit and source record, not the one whose extension looks most sophisticated.
