Hey folks! I’m working on a Telegram bot using the python-telegram-bot library. I’ve got a PIL Image object that I want to send to users directly without saving it as a file first. Here’s what I’ve tried:
bot.send_photo(chat_id=chat_id,
photo=open('image.jpg', 'rb'),
caption='Check this out!',
parse_mode=ParseMode.MARKDOWN)
This works, but it requires saving the image. I’d rather avoid that since I’m generating lots of images and don’t need to keep them.
I create the image by combining multiple images like this:
def create_combined_image(image_list):
total_width = sum(img.width for img in image_list)
max_height = max(img.height for img in image_list)
combined = Image.new('RGBA', (total_width, max_height))
current_x = 0
for img in image_list:
combined.paste(img, (current_x, 0))
current_x += img.width
return combined
# Usage
result_image = create_combined_image([Image.open(path) for path in image_paths])
Any ideas on how to send this PIL Image object directly through the bot? Thanks!
hey Tom_89Paint, i’ve dealt with this before. you can use BytesIO to send the image without saving. here’s a quick example:
from io import BytesIO
buffer = BytesIO()
result_image.save(buffer, format='PNG')
buffer.seek(0)
bot.send_photo(chat_id=chat_id, photo=buffer, caption='Check this out!')
this should work for ya without needing to store files. lmk if u need more help!
I’ve encountered a similar situation in my projects. One efficient approach is to utilize the BytesIO class from the io module. This allows you to work with the image data in memory without writing to disk.
Here’s a code snippet that should solve your problem:
from io import BytesIO
buffer = BytesIO()
result_image.save(buffer, format='PNG')
buffer.seek(0)
bot.send_photo(chat_id=chat_id, photo=buffer, caption='Check this out!', parse_mode=ParseMode.MARKDOWN)
This method is memory-efficient and eliminates the need for temporary file storage. It’s particularly useful when dealing with high volumes of generated images.
I’ve been in your shoes, Tom. When I was developing a bot for a client’s art gallery, we faced the same challenge. Here’s what worked for us:
We used BytesIO, but with a twist. We compressed the image before sending to reduce bandwidth usage and improve response times. Here’s the approach:
from io import BytesIO
import PIL.Image
buffer = BytesIO()
result_image.save(buffer, format='JPEG', quality=85, optimize=True)
buffer.seek(0)
bot.send_photo(chat_id=chat_id, photo=buffer, caption='Check this out!')
The ‘quality’ parameter helped us balance image size and visual quality. We found 85 to be a sweet spot, but you might want to experiment based on your specific needs.
This method was a game-changer for us. It eliminated file storage concerns and significantly improved our bot’s performance. Give it a shot and see if it works for you too!
