I am generating long PDF document with TCPDF.
What I want is to create two versions of this document - one with all pages and one with only 5 pages.
But when I call Output whole document is destroyed and I cannot call Output once again - how to create another document?
Solved problem - I've made instance of Object
$short_pdf= clone $this;

fProcessor.process() method stuck when PDF template with two repeating groups on same page is used.
Is it possible to use two or more repeating groups (not nested) on same page?
FormProcessor fProcessor = new FormProcessor();
fProcessor.setTemplate(args[0]); // Input File (PDF) name
fProcessor.setData(args[1]); // Input XML data file name
fProcessor.setOutput(args[2]); // Output File (PDF) name
fProcessor.process();
Received following reply from oracle support
PDF templates do not support multiple nor nested loops.
You can only use one.
I use the current version of Gatsby (2.x) and want to use gatsby-image for rendering a gallery for products.
I have several YAML files for products. I can already create pages with the text content of these files but I also want to add a small gallery with images specified in the .yaml file.
An example YAML file looks like this:
product: "Some product"
description: "It is really awesome!"
screenshots:
- /img/product1/screenshot1.jpg
- /img/product1/screenshot2.jpg
- /img/product1/screenshot3.jpg
My problem now is that I can get the screenshots only as strings but I have no idea how to pass them to for rendering.
I thought of creating a component that takes the file name and uses a query to get the image data - but it can't take any parameters because it can only use static queries.
I've also not found a way to pass results from the first graphql query to a second for the image data.
If you install gatsby-transformer-sharp and gatsby-plugin-sharp and use a correct path to your images, Gatsby will automatically pick those up and pipe them through sharp, hence you can query those images. You can have a look at one of my sites which also uses a YML file with image paths that I then use with gatsby-image: https://github.com/LekoArts/gatsby-starter-portfolio/blob/master/src/sites/sites.yaml
My understanding of this was that perhaps CGPDFContext is to be used for editing PDF document data and CGPDFDocument is used for storing it, since the documentation doesn't list any ways to alter the content of a CGPDFDocument.
I'm also not quite sure what CGDataConsumer/Provider does. From reading the documentation I got the impression that the consumer/provider abstracts the relationship between the CG object and the CFData it writes to; so I don't have to do that myself. So I figured the following code would create a two page blank PDFdocument:
//Don't know exactly how large a PDF is so I gave it 1 MB for now
self->pdfData = CFDataCreateMutable(kCFAllocatorDefault, 1024);
self->consumerRef = CGDataConsumerCreateWithCFData(self->pdfData);
self.pdfRef = CGPDFContextCreate(self->consumerRef, NULL, NULL);
CGPDFContextBeginPage(self.pdfRef, NULL); //Creates a blank page?
CGPDFContextEndPage(self.pdfRef);
CGPDFContextBeginPage(self.pdfRef, NULL); //Creates a second blank page?
CGPDFContextEndPage(self.pdfRef);
//Copies the data from pdfRef's consumer into docRef's provider?
self.docRef = CGPDFDocumentCreateWithProvider(
CGDataProviderCreateWithCFData(
CFDataCreateCopy(kCFAllocatorDefault, self->pdfData)
));
It didn't work though, and NSLogging the first two pages of docRef returns NULL. I'm rather new at this, the C-Layer stuff in particular. Can someone explain to me the relationship between CGPDFContext, CGPDFDocument, CGDataConsumer & CGDataProvider and how I'd use them to create a blank PDF?
Your basic understanding is correct as far as I can see:
A CGPDFContext is a drawing context that "translates" everything that is drawn onto it to PDF instructions (typically for storage in a PDF file).
A CGPDFDocument is used to open an existing PDF file and get information from it.
When you want to create your own PDF file, you have two ways to do it as described here: https://developer.apple.com/library/mac/documentation/graphicsimaging/reference/CGPDFContext/Reference/reference.html
Use "CGPDFContextCreate" which you pass a data consumer. The data consumer gets the data and can do with it as it pleases (you could create a data consumer that passes the PDF onto the clipboard for example).
Use "CGPDFContextCreateWithURL" which you pass a URL. In that case your data will be written to a PDF file at that URL.
If you want to use these functions, have a look at this page https://developer.apple.com/library/mac/documentation/graphicsimaging/Conceptual/drawingwithquartz2d/dq_pdf/dq_pdf.html#//apple_ref/doc/uid/TP30001066-CH214-TPXREF101 which explains in detail how to create PDF files with a data provider and without (simply to a PDF).
To figure out what is happening I would start by trying to write a simple PDF file to disk before writing one to a data provider and then using that data provider immediately to read it again. Without trying your code however, let me point out that you didn't use "CGPDFContextClose" which is described in the document as closing the PDF document and flushing all information to output. You could actually having a situation where stuff is cached and not written to your data provider yet, simply because you haven't forced that.
This is not working as we discussed previously, for some reason and I have done is create some $vars for the uploaded file.
Code available here (Pastebin).
But never actually inserts anything
When doing a var_dump($csv_row) i get: bool(false)
var_dump($fh) shows: resource(89) of type (stream)
var_dump($insert_str) shows all 1700 records from the csv file (obviously too big to post on here)
So I’m guessing the while statement or the whole from if statement is wrong somewhere. Really really would appreciate some help on this, I need to get it working by tomorrow (monday)
You seem to be using the codeigniter database library wrong. I can see a
$this->db->set($insert_str);
but no $this->db->insert() to be found. The set() method only useful with an update() or insert() following it, See the docs, search for $this->db->set().
You either want to use the $this->db->insert_batch() (on the same doc page, unfortunately no direct links for sections) form and build up an array of arrays with your records (so you won't have to create a long sql string either).
Or you can use the $this->db->query() and just feed the $insert_str to it where you now call $this->db->set().
According to your question:
var_dump($insert_str) shows all 1700 records from the csv file
So i would rule out the possibility of the while loop or the if not working.
Put this code at the top of the controller or before reading csv file
ini_set('auto_detect_line_endings', true);
Check if this will work for you
I just created a GUI using guide in MATLAB for a small project I'm working on. I have amongst other things two text fields for from and to dates. Now I'd like to get rid of them and use a Java date select tool. Of course this is not possible using guide so I need to add them manually.
I've managed to get them to show up by putting this code into my Opening_Fcn,
uicomponent(handles, 'style','com.jidesoft.combobox.DateChooserPanel','tag','til2');
using UICOMPONENT.
But even though it shows up I can't access the date select's attributes, for example
get(handles.til2)
returns
??? Reference to non-existent field 'til2'.
How can I fix this?
Unless you edit the saved GUI figure, the basic handles structure will not include your new component by default.
One way to access you component is to store the handle via guidata, by adding the following to your opening function:
handles.til2 = uicomponent(handles, 'style','com.jidesoft.combobox.DateChooserPanel','tag','til2');
guidata(hObject,handles)
Functions that need to access the handle need the line
handles = guidata(hObject)
to return the full handles structure that includes the filed til2
