If you open first pdf file it's word very good.But
when you open a other pdf file then it's not update.So how can I fix it?Thank you
First every time you call pdf_view(...), a new instance of tkinter Frame is created and pack(), so the second instance of Frame is packed below the first one. But since the first Frame is a bit long, the second one is out of the viewable area and so you cannot see it. You can see the second one by using a smaller height, for example, change from 100 to 50, then you can see both the frames.
To fix the issue, you need to destroy the first instance of the Frame. Also tkPDFViewer uses a class variable img_object_li (a list) to stores all the images (extracted from the PDF file), so you need to clear it before opening another PDF file:
v2 = None # change v2 to global variable
def open():
global v2
file = askopenfile()
if file:
# if old instance exists, destroy it first
if v2:
v2.destroy()
v1 = pdf.ShowPdf()
# clear the stored image list
v1.img_object_li.clear()
# shows the new images extracted from PDF file
v2 = v1.pdf_view(root, pdf_location=file, width=200, height=50) # smaller height
v2.pack()

I have a custom QWidget that I have embedded into a QTableWidget.
When I toggle the QCheckBoxes and modify the text in the QLineEdit widgets, the program is not able to distinguish the widgets in rows 2 and 1 from the widgets in row 0. How can I change the program so that it prints the correct row and column of the QLineEdit widget that is being edited or the Checkbox that is being toggled?
Figure 1 shows a screenshot of the program with the output after selecting the third checkbox many times in Visual Studio Code. The output is expected to read “2 0” repeatedly but instead it reads “0 0”.
Figure 2 Similarly, when I modify the text in the QLineEdit in cell 2,0 from “My Custom Text” to “Text” the program prints “Handle Cell Edited 0,0”, although it is expected to print “Handle Cell Edited 2,0 Cell 2,0 was changed to Text”.

What I've Tried So Far:
I learned that QT has two types of widgets that can be embedded in a table; a QTableWigetItem which can be inserted into a table using setItem()(3) and Qwidgets, which can be placed into a table using setCellWidget().(4) Generally, I know that using a QTableWigetItem one can set the item.setFlags(Qt.ItemFlag.ItemIsUserCheckable)
flag to create a checkbox in the cell. (3) However, when using the QTableWigetItem, I wasn’t able to find a way to indent the checkboxes. Because giving each checkbox its own indentation level is important in the context of my program, I’ve decided to use Qwidgets instead of QTableWigetItems in the few select cells where indenting is important.
I’ve read that by creating a QItemDelegate(5)(6), you can do a lot more with setting QWidgets in boxes. However, creating a delegate seems complicated, so I’d prefer to avoid this if possible. If there is no other way to make the program register the correct cell number of the cell being edited, creating a delegate will be the next thing I look into.
For anyone who might want to experiment with QTableWigetItems in this application, here is an equivalent program that uses QTableWigetItems instead of QWidgets but doesn't permit separate indentation or editing of the text field in column 0. For either and both of these two reasons, a QTableWigetItem seems not to be usable for the checkboxes in column 0.
Less Successful Attempt using QTableWidgetItem:

The geometry of a widget is always relative to its parent.
In your first example, the problem is that the pos() returned for the widget is relative to the myWidget container, and since the vertical position is always a few pixels below the top of the parent (the layout margin), you always get the same value.
The second example has another conceptual problem: the checkbox of a checkable item is not an actual widget, so the widget you get is the table itself.
def handle_cell_edited(self):
# this will print True
print(isinstance(QApplication.focusWidget(), QTableWidget))
As explained above, the geometry is always relative to the parent, so you will actually get the position of the table relative to the window.
The solution to the first case is quite simple, as soon as you understand the relativity of coordinate systems. Note that you shall not rely on the focusWidget() (the widget might not accept focus), but actually get the sender(), which is the object that emitted the signal:
def handleButtonClicked(self):
sender = self.sender()
if not self.table_widget.isAncestorOf(sender):
return
# the widget coordinates must *always* be mapped to the viewport
# of the table, as the headers add margins
pos = sender.mapTo(self.table_widget.viewport(), QPoint())
index = self.table_widget.indexAt(pos)
if index.isValid():
print(index.row(), index.column())
In reality, this might not be that necessary, as an item delegate will suffice if the indentation is the only requirement: the solution is to properly set the option.rect() within initStyleOption() and use a custom role for the indentation:
IndentRole = Qt.UserRole + 1
class IndentDelegate(QStyledItemDelegate):
def initStyleOption(self, opt, index):
super().initStyleOption(opt, index)
indent = index.data(IndentRole)
if indent is not None:
left = min(opt.rect.right(),
opt.rect.x() + indent)
opt.rect.setLeft(left)
class SimpleTable(QTableWidget):
def __init__(self,window):
QTableWidget.__init__(self)
self.window = window
self.setItemDelegateForColumn(0, IndentDelegate(self))
class Window(QWidget):
def __init__(self):
# ...
for i in range(len(items)):
# ...
item.setData(IndentRole, 20 * i)
I am a newbie in OpenCV using Python. I am currently working with a project related opencv using python language. I have a video data set named "VideoDataSet/dynamicBackground/canoe/input" that stores the sequence of image frames and I would like to convert the sequence of frames from the file path to a video. However, I am getting an error when I execute the program. I have tried various codecs but it still gives me the same errors, can any of you please shed some light on what might be wrong? Thank you.
This is my sample code:
import cv2
import numpy as np
import os
import glob as gb
filename = "VideoDataSet/dynamicBackground/canoe/input"
img_path = gb.glob(filename)
videoWriter = cv2.VideoWriter('test.avi', cv2.VideoWriter_fourcc(*'MJPG'),
25, (640,480))
for path in img_path:
img = cv2.imread(path)
img = cv2.resize(img,(640,480))
videoWriter.write(img)
print ("you are success create.")
This is the error:
Error prompt out:cv2.error: OpenCV(3.4.1) D:\Build\OpenCV\opencv-3.4.1\modules\imgproc\src\resize.cpp:4044: error: (-215) ssize.width > 0 && ssize.height > 0 in function cv::resize
(Note: the problem occur with the img = cv2.resize(img,(640,480)))
It is returning this error because you are trying to re-size the directory entry! You need to put:
filename = "VideoDataSet/dynamicBackground/canoe/input/*"
So that it will match all the files in the folder when you glob it. The error actually suggested that the source image had either zero width or zero height. Putting:
print( img_path )
In after your glob attempt showed that it was only returning the directory entry itself.
You subsequently discovered that although it was now generating a file, it was corrupted. This is because you are incorrectly specifying the codec. Replace your fourcc parameter with this:
cv2.VideoWriter_fourcc('M','J','P','G')
you can try this:
img_path = gb.glob(filename)
videoWriter = cv2.VideoWriter('frame2video.avi', cv2.VideoWriter_fourcc(*'MJPG'), 25, (640,480))
for path in img_path:
img = cv2.imread(path)
img = cv2.resize(img,(640,480))
videoWriter.write(img)
I'm trying to learn how to split a pdf every n page.
In my case I want to split a 64p PDF into several chunks containing four pages each: file 1: p.1-4, file 2: p.5-8 etc.
I'm trying to understand PyPDF2 but my noobness overwhelms me:
from PyPDF2 import PdfFileWriter, PdfFileReader
pdf = PdfFileReader('my_pdf.pdf')
I guess I need to make a loop of sorts using addPage and write files till there's no pages left?
Little late but I ran into your question while looking for help trying to do the same thing.
I ended up doing the following, which does what you're asking. Mind you it's probably more than you're asking for, but the answer is in there. It's a rough first draft, in heavy need of refactoring and some variable renaming.
import os
from PyPDF2 import PdfFileReader, PdfFileWriter
def split_pdf(in_pdf, step=1):
"""Splits a given pdf into seperate pdfs and saves
those to a supfolder of the parent pdf's folder, called
splitted_pdf.
Arguments:
in_pdf: [str] Absolute path (and filename) of the

is in the current directory.
step: [int] Desired number of pages in each of the
output pdfs.

num_pages = input_pdf.numPages
input_dir, filename = os.path.split(in_pdf)
filename = os.path.splitext(filename)[0]
output_dir = input_dir + "/" + filename + "_splitted/"
os.mkdir(output_dir)
intervals = range(0, num_pages, step)
intervals = dict(enumerate(intervals, 1))
naming = f'{filename}_p'
count = 0
for key, val in intervals.items():
output_pdf = PdfFileWriter()
if key == len(intervals):
for i in range(val, num_pages):
output_pdf.addPage(input_pdf.getPage(i))
nums = f'{val + 1}' if step == 1 else f'{val + 1}-{val + step}'
with open(f'{output_dir}{naming}{nums}.pdf', 'wb') as outfile:

user.focus_set()

root.mainloop()
You have several things going wrong in your code:
you're calling mainloop twice; you should only ever call it once.
you shouldn't pack or grid widgets inside the notebook. You are packing a widget and then using notebook.add; omit the pack.
you are calling destroy on the root window if the password is good. This causes your application to exit. Don't call destroy.
Normally the way this is done is that the notebook is a child of the root window, and the username/password dialog is an instance of Toplevel. You can hide the root window and pop up the dialog, and then if the user logs in, you can destroy the dialog and un-hide the main window.
I want to know if it is possible to import data of attitude and position (roll/pitch/yaw & xyz) from a comma separated file to Blender?
I recorded data from a little RC car and I want to represent its movement in a 3D world.
I have timestamps too, so if there's a way to animated the movement of the object it'll be superb!!
Any help will be greatly appreciated!!
Best Regards.
A slight modifcation, making use of the csv module
import bpy
import csv
position_vectors = []
filepath = "C:\\Work\\position.log"
csvfile = open(filepath, 'r', newline='')
ofile = csv.reader(csvfile, delimiter=',')
for row in ofile:
position_vectors.append(tuple([float(i) for i in row]))
csvfile.close()
This will get your points into Blender. Note the delimiter parameter in csv.reader, change that accordingly. With a real example file of your RC car we could provide a more complete solution.
For blender v2.62:
If you have a file "positions.log" looking like:

you can read it with this python script in blender (watch out for the indentation!)
import bpy
from mathutils import *
from math import *
from bpy.props import *
import os
import time
# Init
position_vector = []
# Open file
file = open("C:\\Work\\position.log", "r")
# Loop over line in file
for line in file:
# Split line at ";"
splittet_line = line.split(";")
# Append new postion
position_vector.append(
Vector((float(splittet_line[0]),
float(splittet_line[1]),
float(splittet_line[2]))))
# Close file
file.close()
# Get first selected object
selected_object = bpy.context.selected_objects[0]
# Get first selected object
for position in position_vector:
selected_object.location = position
This reads the file and updates the position of the first selected object accordingly. Way forward: What you have to find out is how to set the keyframes for the animation...
Consider this python snippet to add to the solutions above
obj = bpy.context.object
temporalScale=bpy.context.scene.render.fps
for lrt in locRotArray:
obj.location = (lrt[0], lrt[1], lrt[2])
# radians, and do you want XYZ, or ZYX?
obj.rotation_euler = (lrt[3], lrt[4], lrt[5])
time = lrt[6]*temporalScale
obj.keyframe_insert(data_path="location", frame=time)
obj.keyframe_insert(data_path="rotation_euler", frame=time)
I haven't tested it, but it will probably work, and gets you started.
With a spice2xyzv file as input file. The script writed by "Mutant Bob" seems to work.
But the xyz velocity data are km/s not euler angles, I think, and the import does not work for the angles.
# Records are <jd> <x> <y> <z> <vel x> <vel y> <vel z>
# Time is a TDB Julian date
# Position in km
# Velocity in km/sec

Is there a solution to get them in Blender? Should I convert velocity angle to euler, is that possible in fact?
I use this script :
import bpy
from mathutils import *
from math import *
from bpy.props import *
import os
import time
# Init
position_vector = []
# Open file
file = open("D:\\spice2xyzv\\export.xyzv", "r")
obj = bpy.context.object
temporalScale=bpy.context.scene.render.fps
for line in file:
# Split line at ";"
print("line = %s" % line)
line = line.replace("\n","")
locRotArray = line.split(" ")
print("locRotArray = %s" % locRotArray )
#for lrt in locRotArray:
print(locRotArray[1])
obj.location = (float(locRotArray[1]), float(locRotArray[2]), float(locRotArray[3]))
# radians, and do you want XYZ, or ZYX?
obj.rotation_euler = (float(locRotArray[4]), float(locRotArray[5]), float(locRotArray[5]))
time = float(locRotArray[0])*temporalScale
print("time = %s" % time)
obj.keyframe_insert(data_path="location", frame=time)
obj.keyframe_insert(data_path="rotation_euler", frame=time)
