I want to create a pdf document using the TPPDF package in swift.
Is it possible to add in a specific cell multiple items?
I want to add a checkmark as image / Symbol and a related text behind it.
(No accessable element just indicator)
Column A
Column B.
'text'
image + 'text'
'text'
image + 'text'
I needed to split related information's in two rows which get split by the page break.
is it possible to avoid this?
e.g. ObjectA is indicated in 2 rows [row 1 & 2] with some vertical and horizontal merges.
when it comes to a page break, the vertical merges sometimes are divided by the page break.
[Sample Table Image Page break]
[Sample Table Image one object needs 2 rows]
I am new here. Any advice to improve this question to get better support appreciated.
The documents and APIs I noticed did not support anything like this.

I'm currently working on creating a new stencil for several components I use in Visio and I'm stuck at the point of providing proper labels. If you use a resistor from Visio stencil it automatically generates a label "R1" (for first resistor) and "Rk" for the kth resistor. How can I do something similar for my own stencil ?
1- I need to generate a label "ABCD #" (# number automatically generated based on instance count)
2- How can I position the location of this field?
PS:
1- Visio components have a custom defined field which allows for this (which I don't know how to create)
2- For capacitor for example the shapesheet shows an interesting entry
=SETF(GetRef(User.Label),"""C""&"&ThePage!User.AccumulatorCount)&SETF(GetRef(ThePage!User.AccumulatorCount),ThePage!User.AccumulatorCount+1)
which supposedly is how the count and name are generated (I'm not sure how the AccumulatorCount is defined it differs from element to element).
Thank You!
The EventDrop ShapeSheet cells for various electrical shapes have formulas similar to the one you have discovered:
SETF(GetRef(User.Label),"""C""&"&ThePage!User.AccumulatorCount)&SETF(GetRef(ThePage!User.AccumulatorCount),ThePage!User.AccumulatorCount+1)
The ShapeSheet for the page has a cell: User.AccumulatorCount for capacitors. Other User cells will be added as other shapes are dropped. You can set up your own system by adding a User cell to the page, say: User.Widget. Then you place the "Widget" version of the "SETF" formula into your own shapes.
You can create user cells by:
Open the ShapeSheet for the Page (right-click blank area of page, Show ShapeSheet)
Right-click in ShapeSheet and choose Add Section
Add a User-defined cells section
Find the User-defined cells section and similarly add rows to it via
right-clicking
You change the row names by typing over the red, row-name text on the left.
You enter values and formulas in the cells as you would in Excel.
You can toggle viewing formulas vs. viewing values by pressing F5
while in the ShapeSheet.
You have to make the User cell in the page first, so that your shape can reference it. Once your shape references the page cell, you can drag your shape into a stencil, and it will "drag the page User cell along too". So now, you can drop your Widget shape into a new document, and it will create the page User cell on the fly.
The system is basic and fragile. The count only goes up, and never down. If you have shapes with 1, 2, 3, 4 and you delete 1 and 2, the next shape will still be 5.
I have a form where I have to place some fixed data on top and bottom with a variable table in between. If table does not fit on first page, there should be created more pages as needed to acomodate Table.
But for page 2, 3, 4... I still have to print top & bottom, but this time a short version of whats was placed on page 1.
In ItextSharp5 with ColumnText.HasMoreText = true, I know when a new page is needed and can make a new page with proper top & bottom data before drop remaining table.
So how can I achieve same behaviour with iText7?
I did not found a way to know when a table needs some more room
After some reading, found a starting point at Chapter 2: Adding content to a Canvas or a Document
on 3th block of code.
I'm having a hard time figuring out how to individually style a cell or group of cells when a certain thing happens. For instance I would like to be able to right-click on a cell and hit something like "tag" and it would change the background color of the cell to something different. I would like to do the same thing with rows, columns, or any random group of selected cells. I also need this change in style to persist even if the cell(s) are moved beyond the viewport layer's view.
If you have a hard time with NatTable, maybe it is worth reading some of our tutorials and documents.
https://www.eclipse.org/nattable/documentation.php?page=styling
http://www.vogella.com/tutorials/NatTable/article.html
In short related to your question. Individual styling is done via config labels on a cell and styles that are registered in the ConfigRegistry for that label. So what you need to do is to implement some sort of label registry based on cell indeces. That label registry then needs to be used by a custom ConfigLabelAccumulator so the labels are attached to the cells with the corresponding indeces.
We have a basic implementation on a column base via the ColumnStyleEditorDialog. This can be seen in the _000_Styled_grid example by clicking on the column header and call "Format cells". Personally I think that feature is not complete, but it should help you in seeing how it works in principle.
I'm having trouble reading a PDF with header and footer but with 2 columns in your body.
I already have the column widths and height of the header but I need the code to read the pages with columns.
Can anyone provide me a piece of code that reads PDF with columns?
thank you
It's very hard to achieve what you want if you don't know the position of the columns, but I assume that you have its coordinates because you say "I already have the column widths and height". In that case, your question isn't that different from this other question posted on StackOverflow: iTextSharp read from specific position
Suppose that rect is a Rectangle corresponding with the position of a column, then you need this code:
RenderFilter[] filter = {new RegionTextRenderFilter(rect)};
ITextExtractionStrategy strategy = new FilteredTextRenderListener(
new LocationTextExtractionStrategy(), filter);
String single_column = PdfTextExtractor.GetTextFromPage(reader, i, strategy));
Now you have the text in a single column. You need to repeat this for every column on your page.
Extra comment: While in most cases using the RegionTextRenderFilter will work just fine, a few cases (in which columns are created by simply inserting additional space characters in the lines) might require to split the text chunks to process in advance. This can be done e.g. by using the TextRenderInfoSplitter from this answer and wrapping the FilteredTextRenderListener in it. (This comment was provided by mkl.)
I created a .PDF file using Adobe Acrobat Pro. The file has several text fields. Using iTextSharp, I'm able to populate all the fields and mail out the .PDF.
One thing is bugging me - some of the next will not "fit" in the textbox. In Adobe, if I type more that the allocated height, the scroll bar kicks in - this happens when font size is NOT set to auto and multi-line is allowed.
However, when I attempt to set the following properties:
//qSize is float and set to 15;
//auto size of font is not being set here.
pdfFormFields.SetFieldProperty("notification_desc", "textsize", qSize, null);
// set multiline
pdfFormFields.SetFieldProperty("notification_desc", "setfflags", PdfFormField.FF_MULTILINE, null);
//fill the field
pdfFormFields.SetField("notification_desc", complaintinfo.OWNER_DESC);
However upon compilation and after stamping, the scroll bar does not appear in the final .PDF.
I'm not sure if this is the right thing to do. I'm thinking that perhaps I should create a table and flood it with the the text but the documentation makes little or no reference to scroll bars....
When you flatten a document, you remove all interactivity. Expecting working scroll bars on a flattened form, is similar to expecting working scroll bars on printed paper. That's why you don't get a lot of response to your question: it's kind of absurd.
When you fill out a rectangle with text, all text that doesn't fit will be omitted. That's why some people set the font size to 0. In this case, the font size will be adapted to make the text fit. I don't know if that's an option for you as you clearly state that the font size must be 15 pt.
If you can't change the font size, you shouldn't expect the AcroForm form field to adapt itself to the content. ISO-32000-1 is clear about that: the coordinates of a text field are fixed.
Your only alternative is to take control over how iText should fill the field. I made an example showing how to do this in the context of my book: MovieAds.java/MovieAds.cs. In this example, I ask the field for its coordinates:
AcroFields.FieldPosition f = form.GetFieldPositions(TEXT)[0];
This object gives you the page number f.page and a Rectangle f.position. You can use these variables in combination with ColumnText to add the content exactly the way you want to (and to check if all content has been added).
I hope you understand that:
it's only normal that there are no scroll bars on a flattened form,
the standard way of filling out fields clips content that doesn't fit,
you need to do more programming if you want a custom result.
