From cd754900a9192265cddfd0a464b072e7075645c8 Mon Sep 17 00:00:00 2001 From: GeekyGhost <111990299+GeekyGhost@users.noreply.github.com> Date: Thu, 18 Jul 2024 19:14:23 -0400 Subject: [PATCH] Update GeekyRembv2.py Foreground Scaling and Aspect Ratio: New: Introduced separate foreground_scale and foreground_aspect_ratio parameters. Original: Used scale and aspect_ratio parameters. Input Types: New: Removed scale and aspect_ratio from the main INPUT_TYPES and added foreground_scale and foreground_aspect_ratio to the optional inputs. Original: Had scale and aspect_ratio in the optional inputs. Mask Processing: New: Added a separate process_mask method to handle mask operations (inversion, expansion, blurring). Original: Mask processing was done within the process_single_image function. Image Resizing Logic: New: More sophisticated logic for resizing the foreground image, considering both scale and aspect ratio separately. Original: Simpler resizing logic using a single scale factor. Opacity Handling: New: Applied opacity to both the foreground image and its mask separately. Original: Applied opacity to the entire scaled foreground image. Error Handling: New: More specific error handling in the process_single_image function. Original: Less detailed error handling. Code Structure: New: Generally more modular with separate functions for different operations. Original: More operations combined in the process_single_image function. Default Values: New: Introduced default values for foreground scale and aspect ratio based on the original image dimensions. Original: Used fixed default values for scale and aspect ratio. Compatibility: New: Designed to be more flexible with optional parameters for foreground scaling and aspect ratio. Original: Less flexible in terms of foreground image manipulation. Performance Optimizations: New: Potential for better performance due to more efficient mask processing and image manipulation. Original: Less optimized in terms of image and mask processing. --- GeekyRembv2.py | 124 +++++++++++++++++++++++++++++++++---------------- 1 file changed, 84 insertions(+), 40 deletions(-) diff --git a/GeekyRembv2.py b/GeekyRembv2.py index 978fef7..bd656c5 100644 --- a/GeekyRembv2.py +++ b/GeekyRembv2.py @@ -58,14 +58,16 @@ class GeekyRemB: "brightness": ("FLOAT", {"default": 1.0, "min": 0.0, "max": 2.0, "step": 0.1}), "contrast": ("FLOAT", {"default": 1.0, "min": 0.0, "max": 2.0, "step": 0.1}), "saturation": ("FLOAT", {"default": 1.0, "min": 0.0, "max": 2.0, "step": 0.1}), -
