We have users upload images from mobile devices. They show up correctly in browser but when report is carried over to a pdf, they are tilted. PD somehow unable to interpret the file exif info correctly. So,if we want to strip out the file exif info after uploading, how we can do it? I tried by rewriting the image but that did not helped.

I use chartJs to display charts in a web page.
I would like to convert the graphics to an image format and then display them on my web page. I can do this with base64 encoding but I would like to be able to display my images in PNG format.
I'm trying to do this because, afterwards, I export my HMTL file to PDF with Dompdf and the latter does not display the images in base64.
How can I do this?
and I made a project that takes some pictures and converts them to pdf using weasyprint library. everything is alright in localhost but when I deployed it in python anywhere it generates the pdf but pictures that supposed to be in it dosent display and just the replace string of them is in the pdf please help me
Weasyprint might not be able to load the pictures. Check that the URLs you give can be accessed by Weasyprint. When in doubt, try using data URIs which don't require loading over the network.
I have a model with a FileField for document uploads (e.g. images, pdfs, or videos). I use this line in my Document model:
storage_file_name = models.FileField('File name', upload_to=unique_file_path)
and in unique_file_path I change the name of the uploaded document to a unique file name. I find that I will be uploading some tiffs, which I need to change to jpeg or something that a browser can easily display.
I have been looking for the best way to convert the uploaded tiff file to jpeg. Is there a way to do it before the image is saved to the disk, or is the best way to use a
#receiver(models.signals.post_save, sender=Document)
and save the converted image over the saved tiff image?
At this point I am only using the admin pages and not any custom views (except by customizing the admin pages).
Thanks!

I´m trying to save an uploaded jpg in a Shini app, but I can´t find the way.
I upload and image correctly with Fileinput. No problem there.
I want to be able to save that image in the server to use it in the future.
How can I do this?
Thankls!!!
I am looking to have an entry form where you can enter in a server name and end up getting several png images displayed that are created from matpotlib.
I can create the form, and have the scripts written that create the image files. I am wondering what the best way to deal with the images are. Is there a way I can display the resulting png file to the browser but not save it to disk?
Want to avoid cluttering up a directory with the generated images after they are displayed the the browser. Should I just delete the image after its rendered?
response = HttpResponse(mimetype="image/png")
img.save(response, "PNG")
return response
