Extract dominant colors from images using various algorithms including k-means clustering and histogram analysis
Call this tool from your code in three languages.
# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/image-color-extractor' \
-F 'file=@/path/to/imageFile.ext'
# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/image-color-extractor' \
-F 'imageFile=/path/to/file.ext' \
-F 'colorCount=5' \
-F 'algorithm=kmeans' \
-F 'colorFormat=hex' \
-F 'sampleSize=10000' \
-F 'ignoreWhite=false' \
-F 'ignoreBlack=false'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
POST https://api.elysiatools.com/en/api/tools/image-color-extractor| Name | Type | Required | Description |
