Near the edges the shifted copy dominates, so the left and right edges and the top and bottom edges come from neighboring pixels of the same image and meet smoothly. The blend width sets how far in from each edge the fade reaches; it can be at most half the shorter side.\nMirror\nMirror tiling flips the image into a 2 x 2 tile, which always repeats without a visible edge but looks symmetric. It doubles both sides of the image.\nRead the seam report\nThe report gives the mean color difference across the side seam and the top seam, before and after, next to the typical difference between neighboring pixels inside the image. Values near the inside figure mean the seam blends in. Cross-fading can raise the inside figure and strongly patterned textures can still show repeats, so check the preview rather than relying on the tile being perfect.",

Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nImages are processed in this browser and never uploaded. Use still PNG, JPEG or WebP files up to 20 MiB each.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\nAccepted browser files: `.png,.jpg,.jpeg,.webp`. Choose one file.\n\nBrowser file-input limit: 20971520 bytes in total. HTTP limits can differ.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `method` | Tiling method | select | \"cross-fade\" | Allowed: cross-fade, mirror |\n| `blendWidth` | Blend width in pixels | number | \"64\" | min=1 max=4096 step=1 |\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nImages stay in this browser and are never uploaded. Use one still PNG, JPEG or WebP image up to 20 MiB and 16,384 pixels per side: up to 8 million pixels for cross-fade and 2 million pixels for mirror tiling. Blend width 1 to 4,096 pixels and at most half the shorter side. Processing stops after 30 seconds. You get a PNG tile and a JSON seam report. Source metadata and color profiles are not copied.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"seamless-texture-maker\",\n  \"category\": \"image-tools\",\n  \"built\": true,\n  \"requirements\": \"Images stay in this browser and are never uploaded.

Pick cross-fade to keep the original size, or mirror to build a symmetric 2 x 2 tile.\n3. Set the blend width for cross-fade, run the tool and check the repeated preview and seam numbers.\n4. Download the tileable PNG.\n\n## Useful next steps\n\n- [Resize image](https://happytails.ai/en/image-tools/resize-image/) ([Markdown](https://happytails.ai/en/image-tools/resize-image.md))\n\n- [Crop image](https://happytails.ai/en/image-tools/crop-image/) ([Markdown](https://happytails.ai/en/image-tools/crop-image.md))\n\n- [Image difference overlay](https://happytails.ai/en/image-tools/image-difference-overlay/) ([Markdown](https://happytails.ai/en/image-tools/image-difference-overlay.md))\n\n## Cross-fade\n\nThe image is blended with a copy shifted by half its width and height. Near the edges the shifted copy dominates, so the left and right edges and the top and bottom edges come from neighboring pixels of the same image and meet smoothly. The blend width sets how far in from each edge the fade reaches; it can be at most half the shorter side.\n\n### Mirror\n\nMirror tiling flips the image into a 2 x 2 tile, which always repeats without a visible edge but looks symmetric. It doubles both sides of the image.\n\n### Read the seam report\n\nThe report gives the mean color difference across the side seam and the top seam, before and after, next to the typical difference between neighboring pixels inside the image. Values near the inside figure mean the seam blends in. Cross-fading can raise the inside figure and strongly patterned textures can still show repeats, so check the preview rather than relying on the tile being perfect.\n"
