-
I am trying to print a Image in a QFile but its not printing and i donno what is the problem
below is my codeQString header = "<html>\ <body>\ <img src = \"Logo1.png\" alt = \"Test\" >\ </body>\ </html>"; QFile qHtmlFile(qFileName); if(qHtmlFile.open(QIODevice::ReadWrite)) { QTextStream qData(&qHtmlFile); qRep = header; qTextRep.document()->setHtml(qRep); qData << qTextRep.document()->toHtml(); qDebug("Report Created"); // qDebug()<<qRep; } else qDebug() <<qHtmlFile.errorString(); qHtmlFile.close();@ManiRon How do you actually print? Also, you're using a relative path to the image in your HTML, depending on the current directory at runtime it will or will not be found.

@jsulm I have defined path also but the image is not displaying , whether we cannot display a image in a file using QFile concept?
@ManiRon I still don't understand what exactly you're doing: first you say you want to print, now you say you want to display. Can you explain what exactly you're trying to do?
An image file is not directly part of a HTML document. A HTML document can reference images, but these images are stored in files, not in a HTML document. So, I don't know what you expect to see. -

@ManiRon
Like @jsulm I am still at a loss about what you are asking. I don't know what your code is about either, it opens files (for read/write at that), then doesn't use them....All you can do is if your HTML contains
<img src="Logo1.png" alt="Test" >then there needs to be a file named
Logo1.pngin the directory where that HTML is executed from. How it gets there is irrelevant: it might be something already there, you might create it from code, I don't know, but that's what you need.QFileis not needed, and cannot somehow be "passed" to HTML. -

@ManiRon If you don't explain how you're showing or printing your report nobody will be able to help you...
Is this "printing" you meanqData << qTextRep.document()->toHtml();?
To display this report you can simply open the HTML document in a web browser (the picture must be in the same directory as the HTML document!). Or show it in Qt Web Engine. -

@jsulm actually i might have to print some data also thats why i am asking, may be i will show my report how it looks
@ManiRon The code you posted does not print anything (except HTML text to the console), so I'm not sure what your question currently is...
Just to be sure: by "printing" you mean print on a printer? -

@jsulm No sir, I will generate a html file with that code but in that html code i want to place or display an image . I tried but its not displaying
@ManiRon said in how to insert an image in a QFile generated file using HTML:
I tried but its not displaying
So, I guess by "displaying" you mean in a web browser?
Where exactly is the image file located? Is it in the same directory as the HTML file? -

@ManiRon I asked 3 questions. To which question does "yes" belong?
-
So, I guess by "displaying" you mean in a web browser? yes
Where exactly is the image file located? from where i am running my application
Is it in the same directory as the HTML file? No@ManiRon said in how to insert an image in a QFile generated file using HTML:

Well, then I would say this is the problem (and I already said that before: "the picture must be in the same directory as the HTML document!").

@jsulm if i simply give this <img src="Logo1.png" alt="Test" > i have to place my image at place where i am saving my html file . But if i give the path its not accepting at all(means its not showing the image at all)
@ManiRon "i have to place my image at place where i am saving my html file" - yes!
How can web browser know where the picture is if the only information you give it is the file name without path:<img src="Logo1.png" alt="Test" >?! So, where should web browser look for this picture?
"But if i give the path its not accepting at all" - how do you give it the path? Please show... -
