[Bug]: Batch images generated through the API don't create a grid

[watzon]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

The sdapi/v1/txt2img endpoint doesn't create grids when doing batches. Happens with both the batch_size and n_iter parameters.

Steps to reproduce the problem

1. Generate a 4 image batch through the API
2. 4 images are returned, no grid is saved

What should have happened?

Ideally I'd like the ability to tell it whether or not to return the grid, but it should always be saved according to the user's settings.

Agree I guess there is override in api.py file, line 184 Is there a way to get grid from api response?

[chimojiacai]

my current implementation method is to get a single image, and then splice the single image into a grid through code

[kalebbroo]

This has not been resolved right? I think im going to have PIL merge the images into a grid to display in Discord. If anyone knows of a better way please let me know.

[zmhgit]

batch_size=4, the generated pictures are still four pictures, and there is no grid diagram on the webui. How should I deal with this problem

[zmhgit]

这还没解决吧？我想我会让 PIL 将图像合并到网格中以在 Discord 中显示。如果有人知道更好的方法请告诉我。

May I ask how to solve this problem? Do you need to set parameters to directly return to the grid diagram or do you need to manually concatenate the code
