The InstructPixToPixConditioning node prepares conditioning data for InstructPix2Pix image editing by combining positive and negative text prompts with image data. It processes input images through a VAE encoder to create latent representations and attaches these latents to both positive and negative conditioning data. The node automatically handles image dimensions by cropping to multiples of 8 pixels for compatibility with the VAE encoding process.

Inputs

Parameter	Data Type	Required	Range	Description
positive	CONDITIONING	Yes	-	Positive conditioning data containing text prompts and settings for desired image characteristics
negative	CONDITIONING	Yes	-	Negative conditioning data containing text prompts and settings for undesired image characteristics
vae	VAE	Yes	-	VAE model used for encoding input images into latent representations
pixels	IMAGE	Yes	-	Input image to be processed and encoded into latent space

Note: The input image dimensions are automatically adjusted by cropping to the nearest multiple of 8 pixels in both width and height to ensure compatibility with the VAE encoding process.

Outputs

Output Name	Data Type	Description
positive	CONDITIONING	Positive conditioning data with attached latent image representation
negative	CONDITIONING	Negative conditioning data with attached latent image representation
latent	LATENT	Empty latent tensor with the same dimensions as the encoded image
