🔳 CR Aspect Ratio Social Media Input Parameters:

width

The width parameter specifies the initial width of the image before any aspect ratio adjustments are applied. This value is essential for determining the starting dimensions of your image. The width should be set according to the original size of your image or the desired width before scaling. There is no strict minimum or maximum value, but it should be a positive integer that makes sense for your image's resolution.

height

The height parameter specifies the initial height of the image before any aspect ratio adjustments are applied. Similar to the width, this value is crucial for determining the starting dimensions of your image. The height should be set according to the original size of your image or the desired height before scaling. There is no strict minimum or maximum value, but it should be a positive integer that makes sense for your image's resolution.

aspect_ratio

The aspect_ratio parameter allows you to select from a list of predefined aspect ratios tailored for various social media platforms. This parameter ensures that your image is resized and cropped to fit the selected aspect ratio perfectly. Options include "Instagram Portrait

• 1080x1350", "Instagram Square - 1080x1080", "Instagram Landscape - 1080x608", "Instagram Stories/Reels - 1080x1920", "Facebook Landscape - 1080x1350", "Facebook Marketplace - 1200x1200", "Facebook Stories - 1080x1920", "TikTok - 1080x1920", "YouTube Banner - 2560×1440", "LinkedIn Profile Banner - 1584x396", "LinkedIn Page Cover - 1128x191", "LinkedIn Post - 1200x627", "Pinterest Pin Image - 1000x1500", "CivitAI Cover - 1600x400", and "OpenArt App - 1500x1000". The default value is "custom", which allows for manual aspect ratio settings.

swap_dimensions

The swap_dimensions parameter is a boolean flag that, when set to true, swaps the width and height of the image. This can be useful if you need to change the orientation of your image from landscape to portrait or vice versa. The default value is false.

upscale_factor

The upscale_factor parameter determines the factor by which the image should be upscaled. This is useful if you need to increase the resolution of your image to meet specific requirements. The value should be a positive float, with a default value of 1.0, meaning no upscaling.

prescale_factor

The prescale_factor parameter determines the factor by which the image should be prescaled before applying the aspect ratio adjustments. This can help in maintaining image quality during the resizing process. The value should be a positive float, with a default value of 1.0, meaning no prescaling.

batch_size

The batch_size parameter specifies the number of images to be processed in a single batch. This is useful for handling multiple images simultaneously, saving time and effort. The value should be a positive integer, with a default value of 1.
