Metadata cleanup - Maintain metadata within UI (#845)
* Metadata cleanup - Maintain metadata within UI
This commit, when combined with Gradio 3.2.1b1+, maintains image
metadata as an image is passed throughout the UI. For example,
if you generate an image, send it to Image Lab, upscale it, fix faces,
and then drag the resulting image back in to Image Lab, it will still
remember the image generation parameters.
When the image is saved, the metadata will be stripped from it if
save-metadata is not enabled. If the image is saved by *dragging*
out of the UI on to the filesystem it may maintain its metadata.
Note: I have ran into UI responsiveness issues with upgrading Gradio.
Seems there may be some Gradio queue management issues. *Without* the
gradio update this commit will maintain current functionality, but
will not keep meetadata when dragging an image between UI components.
* Move ImageMetadata into its own file
Cleans up webui, enables webui_streamlit et al to use it as well.
* Fix typo

Metadata cleanup - Maintain metadata within UI (#845)
* Metadata cleanup - Maintain metadata within UI
This commit, when combined with Gradio 3.2.1b1+, maintains image
metadata as an image is passed throughout the UI. For example,
if you generate an image, send it to Image Lab, upscale it, fix faces,
and then drag the resulting image back in to Image Lab, it will still
remember the image generation parameters.
When the image is saved, the metadata will be stripped from it if
save-metadata is not enabled. If the image is saved by *dragging*
out of the UI on to the filesystem it may maintain its metadata.
Note: I have ran into UI responsiveness issues with upgrading Gradio.
Seems there may be some Gradio queue management issues. *Without* the
gradio update this commit will maintain current functionality, but
will not keep meetadata when dragging an image between UI components.
* Move ImageMetadata into its own file
Cleans up webui, enables webui_streamlit et al to use it as well.
* Fix typo

Metadata cleanup - Maintain metadata within UI (#845)
* Metadata cleanup - Maintain metadata within UI
This commit, when combined with Gradio 3.2.1b1+, maintains image
metadata as an image is passed throughout the UI. For example,
if you generate an image, send it to Image Lab, upscale it, fix faces,
and then drag the resulting image back in to Image Lab, it will still
remember the image generation parameters.
When the image is saved, the metadata will be stripped from it if
save-metadata is not enabled. If the image is saved by *dragging*
out of the UI on to the filesystem it may maintain its metadata.
Note: I have ran into UI responsiveness issues with upgrading Gradio.
Seems there may be some Gradio queue management issues. *Without* the
gradio update this commit will maintain current functionality, but
will not keep meetadata when dragging an image between UI components.
* Move ImageMetadata into its own file
Cleans up webui, enables webui_streamlit et al to use it as well.
* Fix typo

Metadata cleanup - Maintain metadata within UI (#845)
* Metadata cleanup - Maintain metadata within UI
This commit, when combined with Gradio 3.2.1b1+, maintains image
metadata as an image is passed throughout the UI. For example,
if you generate an image, send it to Image Lab, upscale it, fix faces,
and then drag the resulting image back in to Image Lab, it will still
remember the image generation parameters.
When the image is saved, the metadata will be stripped from it if
save-metadata is not enabled. If the image is saved by *dragging*
out of the UI on to the filesystem it may maintain its metadata.
Note: I have ran into UI responsiveness issues with upgrading Gradio.
Seems there may be some Gradio queue management issues. *Without* the
gradio update this commit will maintain current functionality, but
will not keep meetadata when dragging an image between UI components.
* Move ImageMetadata into its own file
Cleans up webui, enables webui_streamlit et al to use it as well.
* Fix typo

* Metadata cleanup - Maintain metadata within UI
This commit, when combined with Gradio 3.2.1b1+, maintains image
metadata as an image is passed throughout the UI. For example,
if you generate an image, send it to Image Lab, upscale it, fix faces,
and then drag the resulting image back in to Image Lab, it will still
remember the image generation parameters.
When the image is saved, the metadata will be stripped from it if
save-metadata is not enabled. If the image is saved by *dragging*
out of the UI on to the filesystem it may maintain its metadata.
Note: I have ran into UI responsiveness issues with upgrading Gradio.
Seems there may be some Gradio queue management issues. *Without* the
gradio update this commit will maintain current functionality, but
will not keep meetadata when dragging an image between UI components.

## Mask/Crop
* The masking / cropping is very temperamental .
* It may take some time for the image to show when switching from Crop to Mask .
* If the image doesn ' t appear after switching to Mask, switch back to Crop and then back again to Mask
* If the mask appears distorted ( the brush is weirdly shaped instead of round ) , switch back to Crop and then back again to Mask .
## Advanced Editor
* For now the button needs to be clicked twice the first time .
* Once you have edited your image , you _need_ to click the save button for the next step to work .
* Clear the image from the crop editor ( click the x )
* Click " Get Image from Advanced Editor " to get the image you saved . If it doesn ' t work, try opening the editor and saving again.
If it keeps not working , try switching modes again , switch tabs , clear the image or reload .
