這是文生圖的介面，簡單講就是用文字生成圖片，是SD最常用的功能

先上知乎大佬製作的圖，驟眼看花多眼亂，其實很簡單的喵！

首先是第一行

blob

紅框=底模部分安裝包自帶官方模型但很醜=口= 可以刪了 (但如果你之後想自行煉模型建議保留比較好以底模而言聽說蠻實用的泛用性比較強)

VAE的作用是把AI得出的結果變成人類可視化的圖片，可用可不用，但部分模型必須使用指定的VAE

CLIP 別問我是什麼反正調 2 就是

看得懂的話可以看大佬解說：https://zhuanlan.zhihu.com/p/630875053

steps

就是AI用多少步去畫圖

步數愈高細節愈多畫圖時間愈長一般調10-30

**步數愈多不一定愈好，具體視模型要求

sampler

看似很多畫2次元常用只有2個 Euler a / DPM++ 2M Karras

畫3次元真人請用DPM++ SDE Karras

Hires_fix

非常重要！你要高清就要靠它！

550Please respect copyright.ＰＥＮＡＮＡ9pzXev3k0h

寬度高度

圖的尺寸貓羽習慣760X512 圖太大的話AI會亂加東西(比如連體嬰、殘肢、意義不明的色塊)

550Please respect copyright.ＰＥＮＡＮＡpZIVa4GIVR

CFG

數值愈高 AI愈跟你的提示詞(咒語)畫圖

一般7-12

550Please respect copyright.ＰＥＮＡＮＡJ00DdziEwF

總批次數

一次生多少圖

550Please respect copyright.ＰＥＮＡＮＡagIut7mC8h

單批數量

除非你電腦非常強，不然不要按喵！

550Please respect copyright.ＰＥＮＡＮＡ3ifrTxYdVQ

種子

-1=隨機

固定數值會產生一樣的圖像(貓羽試過固定種子沒換咒語之後每次生成都是重複的圖)

550Please respect copyright.ＰＥＮＡＮＡXdM814jZeJ

生成鍵下面的小圖示先不說，重點來了！))))))))))))))))

550Please respect copyright.ＰＥＮＡＮＡ382zWmDxQc

咒語有2種唸法 (貓羽先用基本配置示範)

550Please respect copyright.ＰＥＮＡＮＡJA89Vroc98

1. 完整的英文句子

比如這 girl under water

選好模型和其他參數後成功生成"水底下的少女"圖

進階版是寫段子：(以下是貓羽手抄大佬的咒文)

Picture a lovely fairyland princess standing deep in a fantastic forest. She bears shining wings of pure white, her feathers delicately patterned. Her hair shines like jewels and is adorned with flowers and ribbons. Her large eyes sparkle and shine like stars. The fairyland is as beautiful as in a storybook, dotted with graceful flowers, sparkling waterfalls, and tiny mushroom houses. Her fellow fairies gather around her, enjoying little musical and dance parties. Colorful butterflies dance around her, and the sun's rays shine on her through the trees. She has special magical powers and can sprinkle magic dust covered with stardust and flower scents. In her hand is a magic wand adorned with jewels, which, when wielded, spreads a sparkling magical light that makes the entire forest glow. She goes on adventures with the fairies and communicates with the animals in the forest. She is pure and kind, a source of love and joy from the bottom of her heart. Her smile embraces the fairy land and makes the echoes of nature even more beautiful. Wherever she passes, flowers bloom and birds begin to sing along with her. Her presence has a magical and lovely magic, yet no one can help but love her with all their heart.

教練！我英文不好怎麼辦！

那就寫提示詞吧！

550Please respect copyright.ＰＥＮＡＮＡ5iGlkjPIXR

2.提示詞(prompt)

輸入girl , water , white dress後生成出包括這些元素的圖

**注意喵，你輸入的標簽，AI不一定全用
