ComfyUI Node: STACK (JOV) ➕

STACK (JOV) ➕:

The STACK (JOV) ➕ node is designed to combine multiple images into a single stacked image, providing a powerful tool for AI artists to create complex compositions. This node allows you to specify various parameters such as the axis of stacking, stride, scaling mode, and more, giving you fine control over how the images are combined. By leveraging this node, you can efficiently manage and manipulate multiple images, ensuring they are aligned and scaled according to your artistic vision. The main goal of this node is to streamline the process of image stacking, making it easier to create cohesive and visually appealing compositions.

STACK (JOV) ➕ Input Parameters:

images

A list of images to be stacked. Each image in the list will be processed and combined according to the specified parameters. The quality and alignment of the final stacked image depend on the input images provided.

axis

Defines the axis along which the images will be stacked. Options include horizontal or vertical stacking. This parameter determines the direction in which the images are combined, affecting the overall layout of the final image.

stride

Specifies the stride or step size between stacked images. This parameter controls the spacing between images in the stack, allowing for adjustments in the density and overlap of the images.

mode

Determines the scaling mode to be applied to the images. Options include various scaling algorithms such as NONE, which means no scaling, or other interpolation methods. This parameter affects the resizing of images to fit the desired dimensions.

wihi

A tuple specifying the width and height (w, h) to which the images should be scaled. This parameter is used in conjunction with the scaling mode to resize images, ensuring they fit within the specified dimensions.

sample

Defines the interpolation method used for scaling. Options include different interpolation techniques like LANCZOS4. This parameter influences the quality of the scaled images, affecting the smoothness and clarity of the final output.

matte

A tuple specifying the RGBA values for the matte color to be applied to the images. This parameter allows you to add a background color to the images, which can be useful for creating a consistent look or filling transparent areas.

STACK (JOV) ➕ Output Parameters:

stacked_image

The final stacked image resulting from the combination of the input images according to the specified parameters. This output is a single image that incorporates all the input images, aligned and scaled as per the configuration settings.

STACK (JOV) ➕ Usage Tips:

• Ensure that the input images are of similar dimensions to achieve a more cohesive stacked image.
• Experiment with different axis and stride values to find the best layout for your composition.
• Use the scaling mode and wihi parameters to control the size and resolution of the final image, ensuring it meets your requirements.
• Apply a matte color to fill any transparent areas and create a consistent background for your stacked image.

STACK (JOV) ➕ Common Errors and Solutions:

"no images to stack"

• Explanation: This error occurs when no images are provided as input to the node.
• Solution: Ensure that you provide a list of images to be stacked. Check the input parameters to confirm that the images are correctly specified.

"Invalid axis value"

• Explanation: This error occurs when an invalid axis value is provided.
• Solution: Verify that the axis parameter is set to a valid value, such as horizontal or vertical. Refer to the documentation for acceptable values.

"Scaling mode not recognized"

• Explanation: This error occurs when an unrecognized scaling mode is specified.
• Solution: Ensure that the mode parameter is set to a valid scaling mode. Refer to the available options in the documentation and select an appropriate mode.

"Invalid dimensions in wihi parameter"

• Explanation: This error occurs when the width and height values in the wihi parameter are not valid.
• Solution: Check that the wihi parameter is a tuple containing valid width and height values. Ensure that the dimensions are within acceptable ranges.

"Interpolation method not supported"

• Explanation: This error occurs when an unsupported interpolation method is specified.
• Solution: Verify that the sample parameter is set to a supported interpolation method. Refer to the documentation for a list of valid interpolation techniques.
