Extend a picture on any side, and FLUX.2 Klein 9B paints the new area with Pixaroma's PixaOutpaint LoRA. Your image goes back on top.

FLUX.2 Klein 9B Outpaint

<ul><li>The padding now follows your picture. Pick a ratio or drag the orange handles, and it's worked out for whatever image you load. v1.0 saved it in pixels for the sample, so other pictures could get far too much.</li><li>Fixed the second face under tight portraits. The description used to describe the person, and Klein painted them again under the join. Now it describes only the setting.</li><li>Image Crop + Rotate + Pad replaces Load Image + Pad, which gives you the ratio buttons.</li><li>The workflow is smaller: 14 nodes instead of 24, with the prompt and the painting in two boxes.</li><li>The seam is set to blend in, with Tone match on. The old seam could turn the new area's blacks a hazy gray-green, or leave a line on a turned picture.</li><li>Needs AusBoss nodes 2.5.0 or newer. The models are the same.</li></ul>
