Hi,

Can we embed the image/icon in the table that we create using PLTable?

I know PLImage API is there to create image in the PDF. My specific requirement is to embed the image as an icon in the table cell. Please let me know whether it is supported. If yes, what is the API for the same? A code snippet will be helpful. Thanks.

Regards,
Pankaj

Hi Philip, I'm getting an UnsupportedOperationException in PLImage using certain images.
The exception message is:

Caused by: java.lang.UnsupportedOperationException: BITMASK Transparency JPEG compression is not useful, use LosslessImageFactory instead

My BufferedImage is obtained by from a URL however I'm sorry but I can't give that to you so instead I have attached the image itself.

I've been able to implement my own AbstractPLImage which uses LosslessFactory.createFromImage() to return a PDImageXObject and use this class in place of your PLImage. However I was wondering if you were aware of this problem and decided to raise this issue.

Thank you.

Hello,

I've been using your PH-PDF Layout library for a project and have run into an issue I was hoping you could provide some insight on.

Specifically, I've been having trouble with centering text within a single line. I've been using the .setHorzAlign(EHorzAlignment.CENTER) method on a PLText object, but it seems to only center the text if there's enough text to fill the line, like a long string or multiple strings separated by newline characters.

PLText textField = new PLText(
    "Some Text\n" +
    "-----------------------------------------------------------------------------------------------",
    new FontSpec (PreloadFont.REGULAR, 10)
).setHorzAlign(EHorzAlignment.CENTER);

In this case, the text is properly centered. But when I have a single line of text without the long string of dashes, the text is not centered.

Is there a workaround or method that I may have overlooked to get single line text to center properly within the bounding box?

Thank you in advance for your help and for the effort you've put into developing this library. It's been very useful for my project outside of this issue.

Best regards,
Max

How to make rowspan in table?
I can't find it in test code.

PLTableCell.createEmptyCell() is quite handy but it is currently not possible to define a column span.

How about a variant like PLTableCell.createEmptyCell(int colspan)?

So instead of writing

plTable.addRow(PLTableCell.createEmptyCell(), PLTableCell.createEmptyCell(), PLTableCell.createEmptyCell(), ...)

just

plTable.addRow(PLTableCell.createEmptyCell(3), ...)

Hi,

Thanks for the library, works like charm.
is there a way i can add hyperlink ?

Hi @phax

Is it possible to save a table as an image?

Thanks for the library and your work.

Hello,
I need my table cell hide overflow text, like set "overflow:hidden" style in css
Is there any way to do this?

I am now figuring the max words in a cell by:

        // my cell's width is WidthSpec.perc(30)
        double area=0.3*pages.getAvailableWidth() * this.tableCellHeight-(2*Constants.POINTS_PER_MM*Constants.POINTS_PER_MM);
        double areaPerFont=(fontSize + LINE_SPACING*Constants.POINTS_PER_MM)*fontSize;
        this.tableCellWordsLimit=(int)(area / areaPerFont);

Unfortunately this is not work, the result tableCellWordsLimit is higher than seen.

For high density tables it would be useful to be able to place vertically rotated texts for example in header rows.

Would it be possible to provide a getter for PDPageContentStreamExt within PDPageContentStreamWithCache? There are some methods on PDPageContentStreamExt that I need that are not available on PDPageContentStreamWithCache. (e.g. clip() and drawForm()) I'm currently using reflection to work around this, but would love to have a proper getter method.

Hi @phax,

I might have found a bug with nested tables.

The outer table has two columns and n rows. The table spans multiple pages (this might not be relevant though)
Each row is set up like this:

• in the first column there is a cell with a few mm padding (new PLCell(new PLText).setPadding(x)
• in the second column there is a nested table with n rows, two columns and no padding.

It seems the first cells paddings are not respected in the second columns cell height computation - the cells in each row do not align vertically, the first column is higher in total (I assume by 2*padding).
When I remove the first cell's padding the cells are aligned vertically.

I'll provide a test case if that is required.

Hi,

I am trying to integrate two tables created in ph-pdf-layout with PDFBox. I am not able to add it to PDFBox PDDocument(main document where we add all elements like content, tables, etc).

How can we integrate -

1. PDFs created using PDFBox(with their elements like tables, images) with ph-pdf-layout
   and/or
2. PDF created using ph-pdf-layout(with their elements like tables, images) with PDFBox

I have created a Donut chart using XChart library, which can be integrated with PDFBox, but finally, when I try to integrate with ph-pdf-layout, I have the same problem of not being able to integrate.

Hence, I need help in integrating the PDFBox and XChart with ph-pdf-layout or vice-versa. Thanks.

I have attached the source file for your reference. Thanks.

When we add a header to the first page with 173.78516 height and add another header to other pages with 40.0 height, it reserves 173.78516 for all the headers and in the pages, we see empty space under the smaller header.

This is the message:
PageSet margin top was changed from 40.0 to 173.78516 so that firstPageHeader fits!

I can see from testTextHorzAlignment test in the PLTextTest class how you should right justify a piece of text, but this only seems to work if the text wraps over multiple lines. If I just have a short piece of text, i.e. "Hello world", then that text never seems to be pushed to the right hand page margin. In fact, setting the alignment to LEFT, CENTER or RIGHT makes no difference.

Is there a way to achieve this?

Cheers

I am trying to create the content for a book of puzzles which are like crosswords but are numeric and based on a hexagonal grid.

Each page will have:

1. An image of the puzzle grid.
2. A list of clues grouped by direction (In my case, the clues will have Across, Up, and Down groupings).

The layout of the clues depends on what I can fit on a single page. The pages are 6" by 9" so they are pretty tight.

Here is what I am thinking so far:

1. Have all the clues listed in columns if they will all fit on the same page as the puzzle image.
2. Have the clues "flow" from the first column, into the second, and then the third if they will fit on the page that way.
3. Put all the clues on the opposite (facing) page if they don't fit on the page with the puzzle image and will fit on one page.
4. If nothing else works, put as many clues as I can per page in three columns. Then, on subsequent pages, put whatever remaining clues I need to, but change the heading of the column to indicate it is a continuation like "Across (continued)".

The first step to coding this is to figure out the size of the table containing clues.

I created some test code which creates a table with one cell and then calls table.getPreparedHeight().
But, I get an error:
Cannot invoke "com.helger.pdflayout.spec.SizeSpec.getHeight()" because the return value of "com.helger.pdflayout.base.IPLRenderableObject.getPreparedSize()" is null

I get a similar error if I try to use table.getRenderedHeight().

I guess I need to call something to prepare the table. I see table.prepare(), but that requires a context and I don't see how to get that. I tried looking through the examples but I don't see anywhere which uses it.

It seems this should be simple, but I need someone to point me in the right direction.

Thanks in advance!

Hello,

is it possible to add page numbering to the footer?

Hello,

is it possible to create a vertically splittable table, so that in the meantime no row gets splitted? In instance, when a row has a column with multiple lines of text, it happens, that the row gets splitted on the two successive pages, which i want to avoid, that is, i'd like to keep the rows "atomic".

Thanks, Alex

I have a PDF with multiple tables. For the page break one of these tables is torn apart. Is there a possibility to move the entire table to a new page instead of only some of its rows?

Hey,
found your library a couple days ago and have been playing with it a bit. Works great.
At work we are currently looking into generating pdf-files that could include tables and came across your library.
Among the few libraries out there, yours seems to be more actively developed / maintained.

I noticed, if i understand the code correctly, that there are no "real" tests for pdf-files that are created during tests.
I only see that the pdf-files are saved but no assertions are performed on it.

If thats not the case then feel free to close this issue.
If it is the case, why and does that mean that you test the pdfs manually?

Thanks

When I use Chinese font, there will be a default line break, one line displays two lines.

I get some "?" characters when I write a sentense in Chinese. I have tried almost all the fonts, but it didn't work. I hope to get your response as soon as possible，thank you.

I wanted to see how to create hyperlinks, so there are these sample PDF files:

https://github.com/phax/ph-pdf-layout/tree/master/example-files/plexternallink

And also a sample code:

https://github.com/phax/ph-pdf-layout/blob/master/src/test/java/com/helger/pdflayout/element/link/PLExternalLinkTest.java

So I copied this a bit into a new Android app project, and I also tried to use this in the gradle file (kts formant):

implementation("com.helger:ph-pdf-layout4:5.2.2")}

It can't find the classes.

The docs say to use it this way.
Also it's mentioned here:
https://search.maven.org/artifact/com.helger/ph-pdf-layout4/5.2.2/jar?eh=

But it's weird because the latest version is also said to be 7.1.0...
Attached the problematic sample project. I can also use Java if you wish. Kotlin should be fine though, as it can handle Java easily.

I also tried to reach Jitpack as it might be able to fetch the library, but it failed:
https://jitpack.io/#phax/ph-pdf-layout

What is going on ? What should I use? Maybe the docs weren't updated?

Info: I'm using ph-pdf-layout 7.0.0.

When creating a splittable PLVBox and adding some large non-splittable PLVBoxes as rows, the calculations for vertical splitting seems to go wrong (or at least behaves in a way which I did not expect).
This culminates in a debug message Cannot split because no vertical splittable elements are contained and an error of the form The value of 'StartTop' must be >= 0! The current value is: <negative number>.

By debugging I can see that the PLVBox elements do have too many rows (in m_aRows) which do not fit on the page such that fCurY becomes negative.

I guess, the problem lies in AbstractPLVBox.splitElementVert(...) which uses containsAnyVertSplittableElement() to determine whether splitting can be performed. My expectation is that splitting should be done if each contained row fits in the available height, even if those rows' contents are not splittable.

I have found that there is also a simple workaround for this: just wrap the inner (non-splittable) PLVBox with another splittable one which only contains that inner box.

This is a simple reproduction of the error, the workaround is added as comment in the loop:

public static void main(String[] args) throws Exception {
  var font = new FontSpec(PreloadFont.REGULAR, 10);
  var pageSet = new PLPageSet(new SizeSpec(100, 700));

  var list = new PLVBox(); // splittable
  pageSet.addElement(list);

  for (var i = 0; i < 3; i++) {
    var subList = new PLVBox().setVertSplittable(false); // non-splittable
    subList.addRow(new PLText("test", font).setExactHeight(700));
    list.addRow(subList); // workaround: list.addRow(new PLVBox(subList));
  }

  var pdf = new PageLayoutPDF().addPageSet(pageSet);
  // The following throws an "Internal error" with reason
  // "The value of 'StartTop' must be >= 0! The current value is: -700.0"
  pdf.renderTo(new ByteArrayOutputStream());
}

Sometimes last line of page in multiline text can be rendered using wrong linespace.
Examlpe: https://ibb.co/FWNRYbD

This text was added to document using code

pagesSet.addElement(new PLText(loremRus, italicBoldFont12).setLineSpacing(1.5f));

Last line was rendened with wrong linespace for fitting it into page.
Another lines of text was rendered with correct linespace.

The result document looks strange in this case.

I'm wondering how I can include external fonts. I know how it works with pdfbox directly, but I did not find any solution for ph-pdf-layout.
Normally, the preloaded fonts are good enough, but I need to write fractions like ¾, ½, ¼ etc. inside a text block. Not all of them exist in default fonts, so I need to add FreeSans.

I m working with your dependencies, I have a table with titles etc ...
The issue is that I wanted to set the PreloadFont of the title REGULAR and the text is REGULAR.MEDIUM but after the investigation that I did I couldn't find REGULAR.MEDIUM there's only REGULAR and REGULAR_BOLD there's no medium or light.
So can we solve this problem.

I need to make paragraphs and lists (bulleted and numbered).
How to make indentation of multiline text with prefix (bullet symbol or another text)?

I.e. put a image on the page and then put text over the top?

I want to add a drop cap feature on PLText,
My solution was to copy-and-paste PLText ( I renamed it as PLTextModification)
and I did modifications on methods: onPrepare() & onPerform().

It worked, but it was a horrible hack...

My question : Are there any ways to add drop cap feature on PLText ?

For example, I want to make some part of text bold styled:
This text contains bold part.

Calling pagesSet.addElement(new PLText(lorem, italicFont12)); will add string with specified font. New call of pagesSet.addElement wall add new string.

PLText don't support markups. Also there is not element what containing list of PLText.

Is it possible to solve this problem with current functional?

I'm using ph-pdf-layout4 v5.0.9.

Next code still justify the last line of text:

String lorem = "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, "
          + "sed diam nonumy eirmod tempor invidunt ut labore et dolore magna "
          + "aliquyam erat, sed diam voluptua. At vero eos et accusam et justo "
          + "duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata "
          + "sanctus est Lorem ipsum dolor sit amet.\n\n";

pagesSet.addElement(new PLText(lorem, regularFont12).setHorzAlign(EHorzAlignment.JUSTIFY));

Screen fragment: https://ibb.co/GtKNw4g

Is something wrong in my code? Or it's bug/feature?

Hi,

I have created two tables using PLTable and have added them to PLPageSet aPS1 as below:
aPS1.addElement(aTable);
aPS1.addElement(aTable2);

Then, finally added them to PageLayoutPDF as below:

final PageLayoutPDF aPageLayout = new PageLayoutPDF().setCompressPDF(true);
aPageLayout.addPageSet(aPS1);

But, the two tables are created in two separate pages in PDF. I want to create both tables in the same page in PDF. Please suggest how can I achieve this.

I have attached the source file for your reference.

Thanks.
