## **Seamless Tiling**
|
|
|
|
The seamless tiling mode causes generated images to seamlessly tile with itself. To use it, add the
|
|
`--seamless` option when starting the script which will result in all generated images to tile, or
|
|
for each `dream>` prompt as shown here:
|
|
|
|
```python
|
|
dream> "pond garden with lotus by claude monet" --seamless -s100 -n4
|
|
```

## **Shortcuts: Reusing Seeds**
|
|
|
|
Since it is so common to reuse seeds while refining a prompt, there is now a shortcut as of version
|
|
1.11. Provide a `**-S**` (or `**--seed**`) switch of `-1` to use the seed of the most recent image
|
|
generated. If you produced multiple images with the `**-n**` switch, then you can go back further
|
|
using -2, -3, etc. up to the first image generated by the previous command. Sorry, but you can't go
|
|
back further than one command.
|
|
|
|
Here's an example of using this to do a quick refinement. It also illustrates using the new `**-G**`
|
|
switch to turn on upscaling and face enhancement (see previous section):
|
|
|
|
```bash
|
|
dream> a cute child playing hopscotch -G0.5
|
|
[...]
|
|
outputs/img-samples/000039.3498014304.png: "a cute child playing hopscotch" -s50 -W512 -H512 -C7.5 -mk_lms -S3498014304
|
|
|
|
# I wonder what it will look like if I bump up the steps and set facial enhancement to full strength?
|
|
dream> a cute child playing hopscotch -G1.0 -s100 -S -1
|
|
reusing previous seed 3498014304
|
|
[...]
|
|
outputs/img-samples/000040.3498014304.png: "a cute child playing hopscotch" -G1.0 -s100 -W512 -H512 -C7.5 -mk_lms -S3498014304
|

```

## **Simplified API**
|
|
|
|
For programmers who wish to incorporate stable-diffusion into other products, this repository
|
|
includes a simplified API for text to image generation, which lets you create images from a prompt
|
|
in just three lines of code:
|
|
|
|
```bash
|
|
from ldm.generate import Generate
|
|
g = Generate()
|
|
outputs = g.txt2img("a unicorn in manhattan")
|
|
```
|
|
|
|
Outputs is a list of lists in the format [filename1,seed1],[filename2,seed2]...].
|
|
|
|
Please see ldm/generate.py for more information. A set of example scripts is coming RSN.

## **Preload Models**
|
|
|
|
In situations where you have limited internet connectivity or are blocked behind a firewall, you can
|
|
use the preload script to preload the required files for Stable Diffusion to run.
|
|
|
|
The preload script `scripts/preload_models.py` needs to be run once at least while connected to the
|
|
internet. In the following runs, it will load up the cached versions of the required files from the
|
|
`.cache` directory of the system.
|
|
|
|
```bash
|
|
(ldm) ~/stable-diffusion$ python3 ./scripts/preload_models.py
