ComfyUI Node: Constrain Image 🐍

Constrain Image 🐍| Constrain Image 🐍:

The ConstrainImage| Constrain Image 🐍 node is designed to adjust the dimensions of an image to fit within specified maximum and minimum width and height constraints while maintaining the original aspect ratio. This node is particularly useful for ensuring that images conform to specific size requirements without distorting their proportions. By setting boundaries for the image dimensions, you can ensure consistency and compatibility across various applications, such as web design, digital art, and multimedia projects. The node also offers an option to crop the image if necessary to meet the size constraints, providing flexibility in how the image is adjusted.

Constrain Image 🐍| Constrain Image 🐍 Input Parameters:

images

This parameter accepts the image or images that you want to constrain. The input should be in the format of an image file. The node processes each image individually to ensure they meet the specified size constraints.

max_width

This parameter sets the maximum allowable width for the image. The default value is 1024 pixels, and it must be a non-negative integer. If the image's width exceeds this value, it will be scaled down proportionally to fit within this limit while maintaining the aspect ratio.

max_height

This parameter sets the maximum allowable height for the image. The default value is 1024 pixels, and it must be a non-negative integer. If the image's height exceeds this value, it will be scaled down proportionally to fit within this limit while maintaining the aspect ratio.

min_width

This parameter sets the minimum allowable width for the image. The default value is 0 pixels, and it must be a non-negative integer. If the image's width is less than this value, it will be scaled up proportionally to meet this minimum requirement while maintaining the aspect ratio.

min_height

This parameter sets the minimum allowable height for the image. The default value is 0 pixels, and it must be a non-negative integer. If the image's height is less than this value, it will be scaled up proportionally to meet this minimum requirement while maintaining the aspect ratio.

crop_if_required

This parameter determines whether the image should be cropped if it cannot meet the size constraints through scaling alone. The options are "yes" or "no," with the default being "no." If set to "yes," the image will be cropped to fit within the specified dimensions if necessary.

Constrain Image 🐍| Constrain Image 🐍 Output Parameters:

IMAGE

The output is the adjusted image that meets the specified size constraints. The image will have been scaled and/or cropped as necessary to fit within the maximum and minimum width and height parameters while maintaining the original aspect ratio. This ensures that the image is optimized for your specific requirements without distortion.

Constrain Image 🐍| Constrain Image 🐍 Usage Tips:

• To maintain the original aspect ratio while ensuring the image fits within specific dimensions, set both the maximum and minimum width and height parameters according to your requirements.
• If you need the image to strictly adhere to the size constraints, consider setting the crop_if_required parameter to "yes" to allow cropping when scaling alone is insufficient.
• Use this node to prepare images for web use, ensuring they load quickly and display correctly by fitting within predefined size limits.

Constrain Image 🐍| Constrain Image 🐍 Common Errors and Solutions:

"Invalid image format"

• Explanation: The input provided is not a valid image file.
• Solution: Ensure that the input is a valid image file in a supported format such as JPEG, PNG, or BMP.

"Width or height parameters out of range"

• Explanation: The specified width or height parameters are negative or exceed the allowable range.
• Solution: Verify that all width and height parameters are non-negative integers and within a reasonable range for your application.

"Image cannot be resized to meet constraints"

• Explanation: The image cannot be resized to meet the specified constraints without distortion.
• Solution: Consider enabling the crop_if_required option to allow the image to be cropped to fit within the specified dimensions.
