python - Bug when drawing a QImage on a widget with PIL and PyQt -

-

I'm trying to write a small graphic application, and I need to build a picture PIL that a Showing in the widget. Image has been correctly built (I can check with Imkshow () are), I can convert a QImage are, I normally save to disk (using QImage.save) But if I try to draw it directly on my QWidget, it only shows a white square.

Here I changed the code (Fig QImage commented not working out so QPixmap result in a white square), and I have a temporary file were a dirty hack to save the image and loaded directly into QPixmap that works, but it does not want to know what I am

an idea anyone?

If it's time to try to save his QImage my BMP file, I can use your content to go, but if I try to save it in PNG is completely white < / p>

If the same problem, found that ImageQt objects are not QImages, but just casted for those Can be done 

  #! / Usr / bin / python # - * - coding: UTF -8 - * - # PIL image written PIL by Sebastian stator import cyst in 2010 imports. The PyQt4.QtCore import * def PILimageToQImage (pilimage) from PyQt4.QtGui import * ImageQt import ImageQt: "" "" imageq "QImage PIL image qimage a PIL.ImageQt object converting a PIL image" = ImageQt (pilimage) #convert = QImage (imageq) #cast is the trick that is QImage object for PIL.ImageQt object !!! Return qimage if __name__ == "__main__": #Testcode app = QApplication (sys.argv) PIM = Image.open (. Unicode (QFileDialog () getOpenFileName ())) pim.show () #show PIL image qim = PILimageToQImage (PIM) at = QPixmap (qim) LBL = QLabel () lbl.setPixmap (pm) Lblkshow () #show Qim image sys.exit with labels (app.exec_ ())

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
