# ComfyUI-Image-Selector
|
|
|
|
A custom node for [ComfyUI](https://github.com/comfyanonymous/ComfyUI), which can select one or some of images from a batch.
|
|
|
|
## Background
|
|
|
|
ComfyUI dosn't handle batch generation seeds like A1111 WebUI do (See [Issue #165](https://github.com/comfyanonymous/ComfyUI/issues/165)), so you can't simply increase the generation seed to get the desire image from a batch generation.
|
|
|
|
So here is a simple node that can select some of the images from a batch and pipe through for further use, such as scaling up or "hires fix".
|
|
|
|
Or you can use PreviewImage Node to go through all the images, and then rewire SaveImage with ImageSelector to save the one you want.
|
|
|
|
## Install
|
|
|
|
Clone this repo into `custom_nodes` directory of ComfyUI location
|
|
|
|
## Usage
|
|
|
|
### ImageSelector & ImageDuplicator
|
|
|
|
Both nodes can be found in `image` category.
|
|
|
|
Selector takes a list of selected indexes, start with 1 (not 0, sorry), seperated by comma, and outputs only the selected images from input images.
|
|
|
|
**New in 2023/12/2:** Support range selection with left bound included and right bound excluded, see example below.
|
|
|
|
For example:
|
|
|
|
1. `1`: select the first image
|
|
2. `1,3,4,6,7`: select the 1st, 3rd, 4th, 6th and 7th image
|
|
3. `2:`: select 2nd, 3rd, ..., till the last image (omit the first image)
|
|
4. `:0`: select 1st, 2nd, ..., till the second last image (omit the last image)
|
|
5. `3:-1`: select 3rd, 4th, ..., till the third last image (omit first two and last two images)
|
|
|
|
All indexes that cannot convert to integer or out of bounds will be ignored.
|
|
|
|
Duplicator takes a number and duplicates input images by given times.
|
|
|
|
|
|
|
|
|
|
### LatentSelector & LatentDuplicator
|
|
|
|
Both nodes can be found in `latent` category.
|
|
|
|
The parameters and functionality is just like the image counterpart, but for latents
|

|
## Tips
|
|
|
|
VAE Decode & Encode takes time and vram, so better avoid uneccessary VAE node. If must, do it with as few images/latents as possible. In general,
|
|
- `encode/decode -> duplicator` is better than `duplicator -> encode/decode`
|
|
- `selector -> encode/decode` is better than `encode/decode -> selector`
