how to fix problem of boxes generated by pdf2image while converting pdf to images.?

I'm trying to convert pdf to images using pdf2image but getting problem of extra generated boxes.
This is my input pdf file screenshot
this in input file
from pdf2image import convert_from_path
images = convert_from_path('input_pdf.pdf',output_folder=r'C:\Users\Baith')
images[0].save('output.jpg')
after executing above code got this output
output_file

Since pdf2image is only a thin wrapper around pdftoppm, itself part of poppler, I would advise trying different parameters with the CLI tools to see it a specific combination works.
As for pdf2image itself, you might want to try use_cropbox=True and see if it still add lines.
Feel free to open an issue directly of the repository, if you can provide a sample PDF I would be happy to assist with the issue.

Is there a way to save an inline shape from docx as an image file?

I'm trying to parse a docx file using python-docx. The file contains images and text. Basically i need a way to take an image(an InlineShape object) from the file and save it as a separate image (like "smth.jpg"). Is there a way to do that? From reading the API docs it doesn't seem like it, but maybe i'm missing something.

docx2python will pull these images for you.
from docx2python import docx2python
content = docx2python('my_document.docx', 'output_image_directory')
The images will be in whatever directory you supply.

OK, i've figured put a way. Converting docx file to zip and extracting from there. It's not the best option, but still pretty good for me.

Qt - Loading image with wrong extension

I'm currently working on a Qt program that works with images that are supplied by the users. One problem I've run into is that a lot of images are saved with the wrong extension - e.g. an image is saved in JPG format but has a PNG extension.
Qt doesn't seem to deal well with this. When I load an image like this into a QImage, the QImage fails to load. I've been looking through the docs, but I haven't come across anything relating to this.
Other programs I've used are able to correctly identify the image as a JPG despite the PNG extension, so there should be no reason for Qt to be unable to do this, but I'm not having any luck.
Any suggestions?

I solved this by using a QImageReader. An example is shown below using PySide.
First I created an instance of QImageReader and set it to read the format from the content.
image_reader = QtGui.QImageReader()
image_reader.setDecideFromContent(True)
This setting tells the reader to only look at the image's data to determine its format and not the extension.
Then I set the filename to the filename of the image I wanted to load and called read().
image_reader.setFileName(file_path_here)
image = image_reader.read()
Read returns a QImage object, so I proceeded with the rest of my code from there.

Image to Text scanning in Python-Django

I am currently working in a project in python-django. The user needs to input some data, currently it is done by typing. I want an alternative method to input data, I prefer Image To Text converter. Anyone please help me to implement a method in django-python for the same ?

I suppose you are looking for the pytesser-it is an OCR in python using tesseract. It is used to convert the text in the image in to string.
pytesser can be downloaded from: https://code.google.com/p/pytesser/downloads/list
You will also need PIL to work with images in memory. This can be downloaded from:http://www.pythonware.com/products/pil/
You can select the appropriate version of PIL according to the python version.
Hope this helps.
