ComfyUI Node: Offset Image

Offset Image:

The OffsetImage node is designed to shift or "offset" an image by a specified percentage along the x and y axes. This operation is particularly useful for creating seamless tiles or for artistic effects where you need to reposition the content of an image without altering its dimensions. By adjusting the offset percentages, you can control how much of the image is moved horizontally and vertically, allowing for precise manipulation of the image's layout. This node is essential for tasks that require image alignment or pattern creation, providing a straightforward method to achieve these effects.

Offset Image Input Parameters:

pixels

This parameter represents the input image that you want to offset. The image should be in a format that the node can process, typically a tensor representation of the image.

x_percent

This parameter controls the horizontal offset of the image as a percentage of the image's width. The value ranges from 0.0 to 100.0, with a default of 50.0. A value of 0.0 means no horizontal shift, while 100.0 means the image is shifted by its entire width.

y_percent

This parameter controls the vertical offset of the image as a percentage of the image's height. The value ranges from 0.0 to 100.0, with a default of 50.0. A value of 0.0 means no vertical shift, while 100.0 means the image is shifted by its entire height.

Offset Image Output Parameters:

IMAGE

The output is the offset image, which is the original image shifted according to the specified x and y percentages. The dimensions of the image remain unchanged, but the content is repositioned based on the offset values.

Offset Image Usage Tips:

• To create a seamless tile effect, set both x_percent and y_percent to 50.0. This will shift the image by half its width and height, making the edges align perfectly when tiled.
• Experiment with different x_percent and y_percent values to achieve unique artistic effects, such as creating patterns or aligning specific elements within the image.
• Use this node in combination with other image transformation nodes to create complex image manipulations and effects.

Offset Image Common Errors and Solutions:

"Invalid image format"

• Explanation: The input image is not in a supported format or is corrupted.
• Solution: Ensure that the input image is in a valid format and is not corrupted. Convert the image to a supported format if necessary.

"x_percent or y_percent out of range"

• Explanation: The values for x_percent or y_percent are outside the allowed range of 0.0 to 100.0.
• Solution: Adjust the x_percent and y_percent values to be within the range of 0.0 to 100.0.

"Image dimensions mismatch"

• Explanation: The input image dimensions are not consistent or are not supported by the node.
• Solution: Verify that the input image has consistent dimensions and is in a format supported by the node. Resize or preprocess the image if necessary.
