Summary

Ideogram 4.5 Precise Edit gained a region editing mode in ComfyUI#17428, and the bundled template was updated with it in workflow_templates#1386. The docs page still described Precise Edit as whole-image only.

• Adds an Edit a single region subsection to the Precise Edit section: the context_window options (none / auto / custom), the context_window_mask and context_window_bboxes inputs, the region limits (256 to 4608 px per side, about 4 MP, 6:1), and the effect on image_1 (output keeps the source size from up to 8192x8192 px, any aspect ratio, three reference images with a mask).
• Drops the "output keeps the size of image_1" claim from the section intro, which no longer holds without a region.

Sources checked against current comfy_api_nodes/nodes_ideogram.py: _ideogram_45_context_window_inputs(), _ideogram_45_region(), _ideogram_45_max_source_pixels, and IdeogramPreciseEditApi.execute().

Walkthrough

The Ideogram 4.5 tutorial now documents context_window region editing in English, Spanish, Japanese, Korean, and Chinese. The pages describe region selection, size limits, image handling, and reference-image limits. They also update translation hashes and remove an earlier output-size statement.

Changes: Ideogram 4.5 region-editing documentation

Layer / File(s)	Summary
Localized region-editing documentation tutorials/partner-nodes/ideogram/ideogram-4-5.mdx, es/tutorials/partner-nodes/ideogram/ideogram-4-5.mdx, ja/tutorials/partner-nodes/ideogram/ideogram-4-5.mdx, ko/tutorials/partner-nodes/ideogram/ideogram-4-5.mdx, zh/tutorials/partner-nodes/ideogram/ideogram-4-5.mdx	The pages document none, auto, and custom region modes; region size and aspect-ratio limits; and image and reference-image constraints. They remove the earlier claim that Precise Edit always preserves the input dimensions and update translation hashes.

Suggested reviewers: comfyui-wiki

Priority: Normal

Merge Risk: Low · up to c5c4c

The new region-editing docs overstate size and pixel-preservation guarantees and misdescribe how custom boxes combine. Readers could be misled about edit behavior, but nothing breaks at runtime. Fix the wording in all five language pages, ideally before merge.

- Line 109: Update the mask documentation near the `auto` and
`context_window_mask` entries to state that masks selecting more than 4,194,304
pixels trigger a whole-image edit and that large images may be downscaled, so
`auto` may not preserve source dimensions; apply this documentation change
consistently to all five Ideogram pages.
- Line 110: Update the context_window_bboxes description in each of the five
Ideogram pages to state that it represents one enclosing rectangle around all
connected boxes, including any space between separated boxes, rather than a
union of the boxes.
- Line 104: Qualify the unchanged-pixel guarantee in the `context_window`
region-editing description: explain that pixels outside the region may change
when an oversized source PNG is converted to JPEG for upload. Apply the same
qualification to all five Ideogram 4.5 pages.
- Line 100: Update the Precise Edit description to remove the unconditional
claim that output always matches image_1’s size; state that images above about 4
MP may be downscaled when context_window is none. Apply the same correction to
the corresponding sentence in each translated page.

Remove the unconditional output-size claim.

With context_window set to none, images above about 4 MP are downscaled. This sentence contradicts the new subsection. Update it here and at Line 107 in each translated page. (raw.githubusercontent.com)

Qualify the unchanged-pixel guarantee.

If the source PNG exceeds the upload budget, the node converts it to JPEG before sending it. JPEG compression can change pixels outside the region. Document this exception in all five pages, or preserve the original pixels in the node. (github.com)

Document the oversized-mask fallback.

If the mask selects more than 4,194,304 pixels, Ideogram falls back to a whole-image edit and downscales large images. The node sends such masks without rejecting them, so auto does not always preserve the source dimensions. Add this limit and fallback to all five pages. (developer.ideogram.ai)

Describe the enclosing rectangle, not the box union.

The node builds one rectangle around all connected boxes. For separated boxes, that rectangle also includes the space between them, which is not guaranteed to remain unchanged. Update this description in all five pages. (raw.githubusercontent.com)
