# fasteasySD

<b>fasteasySD</b> is Implementation library of txt2img, img2img function via Latent Consistency Model (LCM) model<br>
This project is designed to enable simple implementation of SD capabilities within other projects 

by creating a comfyUI-lcm extension in a standalone library format.

Original version of comfyUI-lcm : <br>
https://github.com/0xbitches/ComfyUI-LCM

# Usage

<b>This library supports two functions: txt2img and img2img.</b>

### simplest Usage

```Python
#import fasteasySD
from fasteasySD import LCM_base

#make LCM_base class
test = LCM_base.FastEasySD(device='cpu',use_fp16=False)

#make img with img2img mode
test.make_image(mode="img2img",prompt="masterpeice, best quality, anime style",seed=0,steps=4,cfg=8,height=1063,width=827,num_images=1,prompt_strength=0.5,input_image_dir="input.jpg")

#make img with txt2img mode
test.make_image(mode="txt2img",prompt="masterpeice, best quality, anime style",seed=0,steps=4,cfg=8,height=768,width=512,num_images=2)
```

### Usage example : 

```Python
from fasteasySD import FastEasySD

test = FastEasySD(device='cpu',use_fp16=False)

#~~~#

images = test.make(seed=seed,steps=steps,prompt_strength=prompt_strength,cfg=cfg,
                             positive_prompt=prompt,height=height,width=width,num_images=num_images,input_image_dir=input_image_dir)

if mode == "txt2img":
            
    pil_images = test.return_PIL(images)

    images.save_PIL(pils=pil_images,save_name=output_image_dir + "/fesd")

elif mode == "img2img":
            
    images.i2i_batch_save(images_list=images,base_name=output_image_dir + "/fesd_i2i")
```
