# Documentation
|
|
- Class name: easy imageToBase64
|
|
- Category: EasyUse/Image
|
|
- Output node: True
|
|
|
|
easy imageToBase64节点旨在将图像从张量格式转换为Base64编码的字符串。这一功能对于需要通过互联网以文本格式传输图像的Web应用程序和API来说至关重要。
|
|
|
|
# Input types
|
|
## Required
|
|
- image
|
|
- image参数是表示待转换图像的输入张量。它在转换过程中扮演着关键角色，因为它是将被转换成Base64编码字符串的源图像。
|
|
- Comfy dtype: IMAGE
|
|
- Python dtype: torch.Tensor
|
|
|
|
# Output types
|
|
- string
|
|
- 输出是输入图像的Base64编码字符串表示。这种格式广泛用于在HTML或CSS文件中嵌入图像，或在不支持二进制数据传输的网络中传输图像。
|
|
- Comfy dtype: STRING
|
|
- Python dtype: str
|
|
|
|
|
|
## Usage tips
|
|
- Infra type: `CPU`
|
|
- Common nodes: unknown
|
|
|

|
## Source code

"required": {
|
|
"image": ("IMAGE",),
|
|
},
|
|
}
|
|

|
|
|
|
def to_base64(self, image, ):
|
|
import base64
|
|
from io import BytesIO
|
|
|
|
# 将张量图像转换为PIL图像
|
|
pil_image = tensor2pil(image)
|
|
|
|
buffered = BytesIO()
|
|
pil_image.save(buffered, format="JPEG")
|
|
image_bytes = buffered.getvalue()
|
|
|
|
base64_str = base64.b64encode(image_bytes).decode("utf-8")
|
|
return {"result": (base64_str,)}
|
|
|
