suggestion: Parameterize enhancement factors for flexibility
Consider making the enhancement factors (like 2.0 for contrast, 1.5 for brightness) configurable parameters. This would allow for easy adjustment of the 'deepfry' effect without changing the code.
def adjust_color(image, contrast_factor=2.0, brightness_factor=1.5):
logger.info("Adjusting color...")
r = image.split()[0]
r = ImageEnhance.Contrast(r).enhance(contrast_factor)
r = ImageEnhance.Brightness(r).enhance(brightness_factor)
return r
r = adjust_color(pil_image)

suggestion (performance): Consider using a single httpx.AsyncClient instance for the cog
Creating a new AsyncClient for each request may be inefficient. Consider creating a single client instance in the init method and reusing it across the cog.
def __init__(self, bot):
self.bot = bot
self.http_client = httpx.AsyncClient()
async def cog_unload(self):
await self.http_client.aclose()
# In the method where the image is processed:
response = await self.http_client.get(image.url)
| logger.info("Opening image with PIL and HTTPX...") | ||
| async with httpx.AsyncClient() as client: | ||
| response = await client.get(image.url) | ||
| pil_image = Image.open(io.BytesIO(response.content)) |

suggestion: Add error handling for image processing operations
Consider wrapping the image processing operations in a try-except block to catch and handle potential errors, such as corrupted images or unexpected formats.
| pil_image = Image.open(io.BytesIO(response.content)) | |
| try: | |
| pil_image = Image.open(io.BytesIO(response.content)) | |
| except (IOError, OSError) as e: | |
| logger.error(f"Failed to open image: {e}") | |
| raise ValueError("Unable to process the image. It may be corrupted or in an unsupported format.") |
Looking for more commands here, if you have a suggestion add a comment or make a pr to the imagemanipulation branch with the new command.
