-# removeBackgroundColor index.js
-## Imported Code Object
-Certainly! Here's a concise explanation of the `removeBackgroundColor` function:
-
-The `removeBackgroundColor` function is an asynchronous operation that removes a specified background color from an image. It takes the following parameters:
-
-1. `inputPath`: The path to the input image file.
-2. `outputPath`: The path where the processed image will be saved.
-3. `targetColor`: The color to be removed from the image (e.g., '#FFFFFF' for white).
-4. `colorThreshold`: A tolerance value for color matching (default is 0).
-5. `options`: Additional options (not used in the provided code snippet).
-
-The function performs these main steps:
-
-1. Reads the input image using Jimp.
-2. Converts the target color to a hex value.
-3. Scans through each pixel of the image.
-4. Compares each pixel's color to the target color.
-5. If the color difference is within the threshold, it makes that pixel transparent.
-6. Saves the processed image to the specified output path.
-
-This function is useful for removing specific background colors from images, potentially creating transparent backgrounds or isolating objects from their surroundings.
-
-### Third Party Libaries
-
-Yes, this function uses the third-party library Jimp for image processing and manipulation.
-
-### Security Issues
-
-In a brief sentence, there are no apparent direct security issues in the provided code for the removeBackgroundColor function, but it's important to ensure that input validation and proper file handling are implemented when using this function in a larger application context.
