Using iTextSharp i'm trying to align an image so that it gets embedded in a paragraph. I can do it like this:
iTextSharp.text.Image image;
image.Alignment = Image.ALIGN_RIGHT | Image.TEXTWRAP;
document.Add(image);
document.Add(new Paragraph("Large string of text goes here"));
But the image comes out on the top right with the text surrounding it (kind of like an L)
What I want is the text to be a few paragraphs then the image with text below it (kind of like a C). Does anyone know how I would do this VIA iTextSharp?
Edit:
I also tried
iTextSharp.text.Image image;
image.Alignment = Image.ALIGN_RIGHT | Image.TEXTWRAP | Image.ALIGN_MIDDLE;
document.Add(image);
document.Add(new Paragraph("Large string of text goes here"));
But it was displayed with the image at the top and the text below it. There was no textwrap in effect.
The Phrase and the Paragraph objects do behave differently. Try changing to:
image.Alignment = 6;
document.Add(image);
document.Add(new Phrase("Large string of text goes here"));
This worked for me in VB. ( I had to change the image alignment to the sum of the integer values for ALIGN_RIGHT and TEXTWRAP to get this to work properly).
ALIGN_RIGHT = 2
TEXTWRAP = 4
Your image was displayed at the top of the page because it was the first thing added to the document, and the text was added after it.
You can move the image down by either setting its absolute position, or by adding some of your text to the document, then adding the image, then adding the rest of your text.
The easiest way to embed image into paragraph is to use InlineImage from PDFFlow library.
InlineImage was created exactly for this purpose.
Example of adding an inline image with margins:
var imagePath = "imageFile.png";
DocumentBuilder.New()
.AddSection()
.AddParagraph()
.AddTextToParagraph("Inline image")
.AddInlineImage(imagePath, new XSize(16, 16), ScalingMode.UserDefined)
.SetMarginLeft(8)
.SetMarginRight(8)
.ToParagraph()
.AddText("in paragraph.")
.ToDocument()
.Build("Result.pdf");
The above code will generate the following:

Hope, this will help.

let's say I have a bunch of pdf files that I want to migrate into a new pdf. BUT the new pdf file is a table-structured file. And the content of the pdf files should fit in the first cell of a two-column-table.
I am not sure if the approach of working with tables is correct. I am open to any other solutions. All I want is at the end some custom text at the top, followed by pdf content and a checkbox on the right side. (One per pdf content)
What I have so far:
`
PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
Document doc = new Document(pdfDoc, PageSize.A4);
doc.SetMargins(0f, 0f, 18f, 18f);
PdfReader reader = new PdfReader(src);
PdfDocument srcDoc = new PdfDocument(reader);
Table table = new Table(new float[] { 2f, 1f });
PdfFormXObject imagePage = srcDoc.GetFirstPage().CopyAsFormXObject(pdfDoc);
var image = new Image(imagePage);
Cell cell = new Cell().Add(image);
cell.SetHorizontalAlignment(HorizontalAlignment.LEFT);
cell.SetVerticalAlignment(VerticalAlignment.TOP);
table.AddCell(cell);
Table checkTable = new Table(2);
Cell cellCheck1 = new Cell();
cellCheck1.SetNextRenderer(new CheckboxCellRenderer(cellCheck1, "cb1", 0));
cellCheck1.SetHeight(50);
checkTable.AddCell(cellCheck1);
Cell cellCheck2 = new Cell();
cellCheck2.SetNextRenderer(new CheckboxCellRenderer(cellCheck2, "cb2", 1));
cellCheck2.SetHeight(50);
checkTable.AddCell(cellCheck2);
table.AddCell(checkTable);
doc.Add(table);
doc.Close();`
My Problem here is that the pdf content has still its margin. Which completely spoils the design. It is so frustrating, I appreciate any help.
You say
My Problem here is that the pdf content has still its margin. Which completely spoils the design.
PDFs (usually) don't know anything about margins. Thus, you have to detect the margins of the page to import first. You can do this by parsing the page content into an event listener that keeps track of the bounding box of drawing instructions, like the TextMarginFinder. Then you can reduce the source page to those dimensions. This can be done by means of the following method:
PdfPage restrictToText(PdfPage page)
{
TextMarginFinder finder = new TextMarginFinder();
new PdfCanvasProcessor(finder).ProcessPageContent(page);
Rectangle textRect = finder.GetTextRectangle();
page.SetMediaBox(textRect);
page.SetCropBox(textRect);
return page;
}
You apply this method in your code right before you copy the page as form XObject, i.e. you replace
PdfFormXObject imagePage = srcDoc.GetFirstPage().CopyAsFormXObject(pdfDoc);
by
PdfFormXObject imagePage = restrictToText(srcDoc.GetFirstPage()).CopyAsFormXObject(pdfDoc);
This causes the Image this XObject will be embedded in to have the correct size. Unfortunately it will be somewhat mispositioned because the restricted page still has the same coordinate system as the original one, merely its crop box defines a smaller section than before. To fix this, one has to apply an offset, one has to subtract the coordinates of the lower left corner of the page crop box which has become the XObject bounding box. Thus, add after instantiating the Image the following code:
Rectangle bbox = imagePage.GetBBox().ToRectangle();
image.SetProperty(Property.LEFT, -bbox.GetLeft());
image.SetProperty(Property.BOTTOM, -bbox.GetBottom());
image.SetProperty(Property.POSITION, LayoutPosition.RELATIVE);
Now the restricted page is properly positioned in your table cell.
Beware: The TextMarginFinder (as its name indicates) determines the margins by text alone. Thus, if the page contains other contents, too, e.g. decorations like a logo, this logo is ignored and might eventually be cut out. If you want such decorations, too, in your overviews, you have to use a different margin finder class.
I have a richTextBox and I add text and image. Text are not the same color and font. I want to convert to all things for doc file. I am using this codes for this.
wordeaktar.Application wordapp = new wordeaktar.Application();
wordapp.Visible = true;
wordeaktar.Document worddoc;
object wordobj = System.Reflection.Missing.Value;
worddoc = wordapp.Documents.Add(ref wordobj);
wordapp.Selection.TypeText(richTextBox1.Text);
wordapp = null;
enter image description here
This is the image of my richTextBox. How can I do that?
#Gserg's Answer is right!
"richTextBox1.SelectAll(); richTextBox1.Copy(); worddoc.Range().Paste();. However if you simply richTextBox1.SaveFile("...", RichTextBoxStreamType.RichText), Word will be perfectly happy with that. – GSerg"
I seem to have an issue after upgrading iText from 2.1.7 where the PDF seems to be missing or the image has shrunk between pages.
I'm wondering if this is a known issue or if there is something that I need to set in order to fix it.
Some context:
no real calculations have been changed when switching libraries.
the general structure is that we have a Document which has a pdfTable which holds a bunch of pdfImages.
changing between landscape and portrait produces different results.
the images are scaled down so that it will fit the page.
Edit: Sorry, my application was pretty big and does a bunch of work. I had to make a simple mock version before posting the problem
Sample Code (So the numbers are just examples that I used. I basically added a 800*600 Image 5 times using landscape position. I end up seeing only 3 pages when I am expecting 5.)
Note: Using portrait page size shows all 5 but it seems that the sizes vary for some reason.
ByteArrayOutputStream baos = createTemporaryOutputStream();
Document doc = newDocument();
PdfWriter writer = newWriter(doc, baos);
writer.setViewerPreferences(PdfWriter.ALLOW_PRINTING | PdfWriter.PageLayoutSinglePage);
//create page rectangle landscape
Rectangle page = new Rectangle(PageSize.A4.rotate());
doc.setPageSize(page);
doc.setMargins((float)36.0, (float)36.0, (float)36.0, (float)36.0);
doc.open();
//create element pdf table.
PdfPTable table = new PdfPTable(new float[]{(float) 770.0});
table.setWidthPercentage(100);
table.setSplitRows(true);
table.setSplitLate(false);
table.setHeaderRows(0);
// in my case I used 5 800*600 images (same picture)
//then I loop through them and create pdfcell
//and then add it to table which then gets added to the document
List<Image> hi = (List<Image>) model.get("images");
for (Image image : hi) {
com.itextpdf.text.Image pdfImage = com.itextpdf.text.Image.getInstance(image.getBytes());
pdfImage.scalePercent((float) (0.8642384 * 100));
PdfPCell cell = new PdfPCell(pdfImage, false);
table.addCell(cell);
}
doc.add(table);
doc.close();
I have a pdf which include text written in Type 3 Font.
I want to get some text from it and write it into other pdf in exactly same shape.
I am using itext. Please give me a tip.
edit: I attached my code.
DocumentFont f = renderInfo.getFont();
String str = renderInfo.getText();
x = renderInfo.getBaseline().getStartPoint().get(Vector.I1);
In this code, I want to write str into x value position.
In Type 3 Font, is it work?
You can copy parts of one page to a new one using code like this:
InputStream resourceStream = getClass().getResourceAsStream("from.pdf");
PdfReader reader = new PdfReader(new FileOutputStream("from.pdf"));
Rectangle pagesize = reader.getPageSizeWithRotation(1);
Document document = new Document(pagesize);
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("areaOfFrom.pdf"));
document.open();
PdfContentByte content = writer.getDirectContent();
PdfImportedPage page = writer.getImportedPage(reader, 1);
content.saveState();
content.rectangle(0, 350, 360, 475);
content.clip();
content.newPath();
content.addTemplate(page, 0, 0);
content.restoreState();
document.close();
reader.close();
This turns your
into
Unfortunately, though, that hidden content is merely... hidden... but it is still there. You can especially mark the lines with that hidden text and try to copy&paste them.
If you want to completely remove that hidden text (or start out by merely copying the desired text), you have to inspect the content of the imported page and filter it. I'm afraid iText does not yet explicitly support something like that. It can be done using the iText lowlevel API but it is quite some work.
I am trying to insert id and name for image inside tinymce.
var content=tinyMCE.get('faq_answer').getContent()+"--img tag is given here--";
I can add image inside tinymce by giving alt, title but i cant add id and name.
If you want to add an element at the end of your editors content i would do something like this (this way you do not have to get all the editors content and set it again):
var doc = ed.getDoc();
// create a new img element
var img = doc.createElement('img');
img.title = 'title';
img.src = '/images/my_image.gif';
img.id = 'my_id';
img.name = 'imagename';
// add the new img element to the dom
ed.getBody().appendChild(img);
Some attributes may vanish (be cleaned up) depending on the configuration of valid elements. If this configuration is not set a standard rule set will apply. You may extend this rule set using the extended valid elements option. There is a nice example concerning img elements :)
