This string parameter sets the prefix for the filenames of the saved images. By default, it is set to "LMCQ", allowing you to easily identify and organize your saved files.

format

This parameter allows you to choose the file format for saving images. Options include "png", "jpg", and "webp". Selecting the appropriate format can impact the image quality and file size.

quality

An integer parameter that determines the quality of the saved image, particularly for lossy formats like JPG. It ranges from 1 to 100, with a default value of 95, allowing you to balance between image quality and file size.

apply_watermark

A boolean parameter that specifies whether a watermark should be applied to the images. By default, it is set to False, meaning no watermark will be added unless specified.

watermark_type

This parameter lets you choose the type of watermark to apply, either "text" or "image". It works in conjunction with other watermark-related parameters to customize the watermark's appearance.

watermark_text

A string parameter for the text to be used as a watermark. It is only applicable if the watermark type is set to "text". By default, it is an empty string.

watermark_size

An integer parameter that defines the size of the watermark. It ranges from 0 to 80, with a default value of 15, allowing you to adjust the prominence of the watermark on the image.

watermark_position

This parameter specifies the position of the watermark on the image. Options include "Bottom Right", "Bottom Left", "Top Right", "Top Left", "Center", "Left", "Right", "Top", and "Bottom".

watermark_opacity

A float parameter that controls the transparency of the watermark, ranging from 0.0 (completely transparent) to 1.0 (completely opaque), with a default value of 0.5.

enhance_brightness
