You set the height and the width to change the image size in pixel space. If you want latent scale on input size, yes you can use comfyroll nodes or any similar to get image resolution. You can effectively do an img2img by taking a finished image and doing VAE Encode->KSampler->VAE Decode->save image, assuming you want a sort of loopback thing. It has a Latent node as an output which connects to the Latent input node of the KSampler. These nodes can be used to load images for img2img workflows, save results, or e.

Copy link kyle215ps3 commented Apr 30, 2023 • If the weight number is less than 1, it means that the relevance of this word decreases in the generated image. a latent image – occurs in silver halide crystals that are struck by a sufficient number of photons. So, if you want to change the size of the image, you change the size of the latent image. There is making a batch using the Empty Latent Image node, batch_size widget, and there is making a batch in the control panel. It will output width/height, in which you pass them to empty latent (where width/height converted to input). The final workflow should look like this: From the workflow, it's not hard to see that essentially, it involves first encoding the image, then encoding the text prompt, finally fusing the two, and inputting them into the model. All of the batched items will process until they are all done. f. inputs¶ latent.
