Does someone do loading font file in iTextPDF from database? When loading font, for example:
BaseFont.createFont("res/mycustomfont.ttf", BaseFont.CP1250, BaseFont.EMBEDDED)
it's loaded from local filesystem.
I have read iText in action 2E, (especialy I have repeated chapter 11 now) but none about loading fonts from database, just how to load them from file system.
Going through source code, looks that for true type font (example above) the real data read is done in TrueTypeFont#process(byte ttfAfm[], boolean preload) and it reads from local filesystem only.
Curious if someone have override it for reading font data from DB?

I am trying to "automate" the building of a PDF using Apache FOP and Java. I want to minimize the hard coding since I don't know in advance all the file combinations I am going to need to support. In addition I want to try and not save files on the hard drive. Files on the HD introduces security, performance, threading and cleanup considerations I would rather not handle.
The test case I am using right now has 1 FO and 2 PNG files. One of the PNG files is over 1MB.
Ideally I would create 3 sources:
InputStream fo = new InputStream(new File("C:\\Temp\\FOP\\Test\\blah.fo"));
InputStream png1 = new InputStream(new File("C:\\Temp\\FOP\\Test\\image-1.png"));
InputStream png2 = new InputStream(new File("C:\\Temp\\FOP\\Test\\image-2.png"));
Source foSrc = new StreamSource(fo);
Source png1Src = new StreamSource(png1);
Source png2Src = new StreamSource(png2);
and then combine them all together to generate the PDF. I can't find a way using the API to do that.
The FO files refers to the images via:
<fo:external-graphic src="file:image-1.png"/>
<fo:external-graphic src="file:image-2.png"/>
When I use the command line FOP tools, it builds the PDF as I would expect. As long as the two images are in the same directory as the FO file, then all is good. Using the command line, there is no need to point out the existence or location of the images.
When using Java, I have tried a number of configurations, but none of them fit my need:
I saved the FO file and the 2 images into the same directory and referred to them using the following FopFactory constructor:
private static final FopFactory fopFactory = FopFactory.newInstance(new File("C:\\Temp\\FOP\\test").toURI());
This code base only finds the smaller of the two images. It seems like the larger one is being ignored since it is bigger than some limit.
I have tried the above constructor using various relative and absolute paths.
I have tried constructing FopFactory using the default "fop.xconf" file and adding the "C:\Temp\FOP\Test" directory to the classpath.
I have "hardcoded" the files and their locations in the FO file.
I have tried using intermediate files structure (IFDocumentHandler, IFSerializer and IFConcatenator) for the images and get errors that way. Seems the intermediate files are not intended for images.
I have been able to embed the file into the FO file using base64 encoding and the syntax:
<fo:external-graphic src="url('data:image/png;base64,iVBORw...ggg==')"/>
The last one seems like the best solution other than taking 3 sources and using all 3 to generate the PDF. Any suggestions on how to use the API to combine the 3 sources?
Thanks.

I am working on PdfBox and generated PDF successfully as per requirement on Windows. But when running my solution on Unix/Linux and it is generating the PDFs as per requirement. When we tried to open the PDF with Adobe Acrobat Reader DC version it is giving Pop-up The font 'ABCDEE+Calibri' contains bad/widts. I moved the PDF to windows from linux and tried to open the pdf , now its poping up on windows as well. I have not used calibri anywhere on my pdf. I used TrueTypeFont to load.ttc file as .ttf file. Apart from that there is no great logic as well.
Map<String, PDFont> suppFonts = new HashMap<>();
PDFont arial = PDType0Font.load(pddoc, <<className>>.class.getResourceAsStream("/path/to/the/file.ttf").getInputStream());
PDFont mingliu = PDType0Font.load(pddoc, new TrueTypeCollection(<<className>>.class.getResourceAsStream("/path/to/the/file.ttc").getInputStream());
suppFonts .put("arial",arial);
suppFonts .put("mingliu",mingliu);
we used this HashMap and retrieved font with the name we have given such as arial,mingliu..etc.
Please help me if you have faced such kind of issue earlier.
I have a PDF template created in Acrobat Reader DC which contains a field that I trying to fill with some text. The field has a specific font that I want to keep. I am able to obtain the field and change the value.
However, when I open the PDF in Internet Explorer the font is a default font. The confusing part is that if I open it in Chrome then it shows the correct font. Not sure why that is, any help is appreciated. I am using PDFBox version 2.
(The font works if I don't use Java to edit the file, if I just manually change it inside Acrobat and save the file then it shows correctly.)
See below for the code used.
File file = new File("PDFToReadFrom.pdf");
PDDocument pdDoc = PDDocument.load(file);
PDDocumentCatalog pdCatalog = pdDoc.getDocumentCatalog();
PDAcroForm pdAcroForm = pdCatalog.getAcroForm();
for(PDField pdField : pdAcroForm.getFields()){
pdField.setValue("value");
}
pdDoc.save(new File("test.pdf"));
pdDoc.close();
I suggest you'd better to compare the PDF file (Use Java edited file and the Acrobat generated file), whether they are using the same font.
According to this article, it seems that we could set the font when using PDFBox to create a PDF file.
I would like to create a copy of word or excel file using poi.
I know that poi is also used when reading a word or excel file. Reading means not only values but also attribute such as font size or table color and backgroud colors for each cells. Reading values and attribute of the xlsx or docx document, I want to make a copy of the word or Excel document as it is. Is it possible that the related source is open at open source on the any site?
read Apache POI or docx4j for dealing with docx documents
you can find the techniques related to adding text into document you can found out on https://www.slideshare.net/plutext/document-generation-2012osdcsydney
use POI's HWPF support. this is often enclosed in docx4j as a dependency. however its not an excellent approach, since it does not convert the doc to docx4j's internal representation:- you are kind of stuck in HWPF land
use JODConverter to convert the doc to a docx, and if necessary, back again. this is often the simplest .
To open an excel from one file, and save it to another file I use this code.
//open source excel
InputStream template = new FileInputStream("C:\\source excel path\\input.xlsx");
Workbook wb = WorkbookFactory.create(template);
//Saving excel to a different location or filename.
FileOutputStream out = new FileOutputStream("C:\\path to copy excel to\\output.xlsx");
wb.write(out);
wb.close();
out.close();
template.close();
So I have the following problem. I receive a PDF file which contains a set of fonts. These fonts are not embedded into the file. Here is a simple example:
I would like to embed these fonts inside the PDF, so they're self-contained and always available. But things don't seem that simple. I'm using IText to do my PDF processing.
I have read and tried the following questions/answers:
how-to-create-pdf-with-font-information-and-embed-actual-font-when-merging-them
embed-truetype-fonts-in-existing-pdf
embed-font-into-pdf-file-by-using-itext
how-to-check-that-all-used-fonts-are-embedded-in-pdf-with-java-itext
Chapter 16.1.4 Replacing a font of the book iText in Action - 2nd Edition
...
But what had gotten me closest was the following example: EmbedFontPostFacto.java (which comes from the book). I was able to embed the Arial font when providing the Arial.ttf file.
But with this, like with other examples, I need the source file of the font in order to embed it. In my case, I don't have the source file. But I might have them on the system however. So I'd like to query my available fonts on the system and see if it corresponds to the given font.
Something of the likes as
GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();
java.awt.Font[] fonts = e.getAllFonts();
for(java.awt.Font f : fonts){
System.out.println(f.getFontName());
}
But I cannot transform the given java.awt.Font into a RandomAccessFile or a byte[] to be used in order to embed the font file itself. Is there another way for embedding fonts into a PDF, without having the source file of the font itself?
For Windows C:\Windows\Fonts or such contain all font files, and in the explorer shows also font names. So a manual search is feasible.
In java, you have GraphicsEnvironment.getAvailableFontFamilyNames() and Font.getFamilyName() to check for a name from the PDF like "Arial MT."
However a getter for the file is missing from Font.
So list all files of the font directory, and load each file consecutively as Font.
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
Font font = Font.createFont(Font.TRUETYPE_FONT, ttfFile);
ge.registerFont(font); // If you want to load the font.
if (pdfFontName.startsWith(font.getFamilyName()) {
System.out.printf("%s - %s / %s%n", ttfFile.getName(), font.getFamilyName(),
font.getName());
}
