The Nodes

Set Global Variable

The Set Global Variable node allows you to store your data in variables.

See More Information

The Input and Output nodes form a direct pipeline for better integration within workflows.

The variable data is used for inputting variable values.

Scope is used to set the order in which variables are obtained. You just need to connect them in sequence one after another.

variable_name Here you can set the name of your variable.

Get Global Variable

The Get Global Variable node can retrieve data stored in variables.

See More Information

The Input and Output nodes form a direct pipeline for better integration within workflows.

variable data is used for outputting the variable's value.

Scope is used to set the order in which variables are obtained. You just need to connect them in sequence one after another.

variable_name Here you can specify the variable you want to retrieve.

Inversed Switch

Used to control the direction of the workflow.

See More Information

Connect the main workflow to the Input interface, then connect the Output to different branch workflows. By controlling the path value of the node, you can determine which branch the workflow will take.

This node needs to be used in conjunction with Switch.

The core logic of this node draws inspiration from ComfyUI-Impact-Pack. We would like to express our gratitude to the author of ComfyUI-Impact-Pack here.

Switch

Select and retrieve data from different processes.

See More Information

This node is usually used in conjunction with the Inversed Switch node; of course, you can also use it independently.

The Input interface connects to different branch workflows, while the Output interface will output data from the corresponding workflow based on the value of path.

Dominant Axis Scale

Smart scale input group A relative to input group B, using its longest side as the scaling axis.

See More Information

Height a, Width a — these are the input dimensions you need to scale.

Height b, Width b — these reference dimensions serve as the scaling baseline, which you can conceptualize as canvas dimensions.

ratio — Input your scaling factor here.

The output Width, Height, and scale_ratio govern different output formats.

Area Based Scale

Smart scale the area of input group A with reference to input group B, based on size.

See More Information

Height a, Width a — these are the input dimensions you need to scale.

Height b, Width b — these reference dimensions serve as the scaling baseline, which you can conceptualize as canvas dimensions.

ratio — Input your scaling factor here.

The output Width, Height, and scale_ratio govern different output formats.

cap_threshold — the upper scaling limit threshold, beyond which the object will not scale any.

enable_cap — threshold activation switch.

Area Based Scale (Pixel)

Smart scale the area of input group A with reference to input group B, based on Pixel.

See More Information

The image_alpha port connects to an image with a transparency channel. You may need to use it in conjunction with ApplyMaskToAlpha. Unless you explicitly clear the transparency information of the image, please use it alongside ApplyMaskToAlpha to generate an image with transparency channel information. For specific usage, refer to the ApplyMaskToAlpha section.

The image input port is used to connect the background image, or it can be referred to as the reference for scaling.

Get Image Size

Get Image Dimensions.

See More Information

Get Mask Size

Get Mask Dimensions.

See More Information

Overlay Text & Text Block

The function of drawing text on images consists of two nodes: a parent node and a child node. The parent node is Overlay Text, which is used to control the overall settings, while the child node is Text Block, responsible for controlling individual text blocks. These two nodes work together to build a powerful text system with professional-level text adjustment functions.

See More Information

The text_block input of Overlay Text is used to connect text blocks. If multiple styles need to be controlled separately, connect multiple text blocks.

Gradient

Used to generate gradients or transparent gradients for images.

See More Information

gradient_type is used to set the gradient style.

rotation_angle is used to set the gradient direction.

The position series settings are used to control the gradient effect in detail.

The color series settings are used to set gradient colors.

The alpha series settings are used to set gradient transparency.

The mask output port will output the corresponding mask based on the transparent gradient.

ApplyMaskToAlpha

Set the image transparency based on the mask.

See More Information

Connect the mask information to the mask input, and it will output an image with an alpha channel.

ImageHasAlpha

Determine whether the image contains transparency channel information.

See More Information

Baseline Alignment (X) & Baseline Alignment (Y)

Input two different heights, then set a baseline. The output will be how much the center position of height a needs to be adjusted so that its bottom position aligns with the baseline position of height b.

Jimeng Image 4.0

Jimeng Image 4.0 node.

See More Information

Please go to 火山引擎 to complete the key application.

Since Jimeng 4.0 does not currently support base64, please go to PicGo to obtain the image hosting key.
