I just started using this library.
How can i position text in a cell at middle and at bottom?
PdfFont font = PdfFontFactory.createFont(StandardFonts.HELVETICA_BOLD);
Paragraph para = new Paragraph("Test").setFont(font);
Table table = new Table(UnitValue.createPercentArray(1)).useAllAvailableWidth();
Cell cell = new Cell();
cell.setMinHeight(100);
cell.setVerticalAlignment(VerticalAlignment.MIDDLE);
cell.add(para);
cell.add(new Paragraph("test")).setVerticalAlignment(VerticalAlignment.BOTTOM);
table.addCell(cell);
Currently setting the vertical alignment the content is aligned to the bottom. The output:
How can I achieve the position of text at middle and bottom?
Like this with in the same cell:
Thanks.
PdfFont font = PdfFontFactory.createFont(StandardFonts.HELVETICA_BOLD);
Paragraph para = new Paragraph("Test").setFont(font);
Table table = new
Table(UnitValue.createPercentArray(1)).useAllAvailableWidth();
table.setHorizontalAlignment(HorizontalAlignment.CENTER);
table.setTextAlignment(TextAlignment.CENTER);
Cell cell = new Cell();
cell.setMinHeight(100);
cell.setVerticalAlignment(VerticalAlignment.MIDDLE);
cell.add(para);
cell.add(new Paragraph("test")).setVerticalAlignment(VerticalAlignment.BOTTOM);
table.addCell(cell);

Cell SubTitle = new Cell().setBold();
Cell CA1Title = new Cell().setBold().setTextAlignment(TextAlignment.CENTER);
Cell CA2Title = new Cell().setBold().setTextAlignment(TextAlignment.CENTER);
Cell ExamTitle = new Cell().setBold().setTextAlignment(TextAlignment.CENTER);
Cell TotalTitle = new Cell().setBold().setTextAlignment(TextAlignment.CENTER);
Cell RemarkTitle = new Cell().setBold();
SubTitle.add("Subject");
CA1Title.add("1st C.A");
CA2Title.add("2nd C.A");
ExamTitle.add("Exam");
TotalTitle.add("Total Score");
RemarkTitle.add("Remark");
The method Cell.add() doesn't accept argument(String).
What is the problem?
In iText, not all elements can accept just "simple" text - some elements are containers for other "Block" elements, whereas the Text is a Leaf element. Actual text is represented by objects of Text or Paragraph type:
Text text1 = new Text("Text 1");
Paragraph p1 = new Paragraph(text1);
Paragraph p2 = new Paragraph("Text 2");
The Cell itself (as its documentation says) is simply a container that holds other elements (and provides col/row spanning for Tables). So to add text to it you need to give it a Paragraph element to hold onto:
Cell myCell = new Cell()
.add(new Paragraph("My Cell Title"))
.setBold()
.setTextAlignment(TextAlignment.CENTER);

Right aligning text in PdfPCell

I have a table where in the first row there are only images and in the second row there are only descriptions of the images. I handle this by creating a table with the size (columns) of the amount of images and then filling the cells with tables with size 1 (2 rows = 1st row the image, 2nd row the description). After setting cell alignment of the 1st row to center, the second row will not apply the align and the description stays on the left ... is this a bug?
Integer size = filepathArray.length;
PdfPTable pdfPTable = new PdfPTable(size);
for (int i = 0; i < size; i++) {
PdfPTable inner = new PdfPTable(1);
try {
PdfPCell image = new PdfPCell();
PdfPCell description = new PdfPCell();
PdfPCell cell = new PdfPCell();
image.setImage(Image.getInstance(getImageAsByteArray(filepathArray[i])));
image.setFixedHeight(32);
image.setBorder(Rectangle.NO_BORDER);
image.setHorizontalAlignment(Element.ALIGN_CENTER);
inner.addCell(image);
description.addElement(new Chunk(filepathArray[i], FontFactory.getFont("Arial", 8)));
description.setBorder(Rectangle.NO_BORDER);
description.setHorizontalAlignment(Element.ALIGN_CENTER);
inner.addCell(description);
cell = new PdfPCell();
cell.addElement(inner); // needed to actually remove the border from the cell which contains the inner table because tables have no setter for the border
cell.setBorder(Rectangle.NO_BORDER);
pdfPTable.addCell(cell);
} catch (Exception e) {
}
}
pdfPTable.setHorizontalAlignment(Element.ALIGN_LEFT);
Result: the image is centered, the text is not, no way, I've tried everything! Also addElement() removes all previously set alignments (table and cell elements, is this a bug?) so I have to set the alignment AFTER I added the content to the cell or table.
This is wrong:
PdfPCell description = new PdfPCell();
description.addElement(new Chunk(filepathArray[i], FontFactory.getFont("Arial", 8)));
description.setHorizontalAlignment(Element.ALIGN_CENTER);
It is wrong because you are mixing text mode:
PdfPCell description = new PdfPCell(new Phrase(filepathArray[i], FontFactory.getFont("Arial", 8)));
description.setHorizontalAlignment(Element.ALIGN_CENTER);
With composite mode:
PdfPCell description = new PdfPCell();
Paragraph p = new Paragraph(filepathArray[i], FontFactory.getFont("Arial", 8));
p.setAlignment(Element.ALIGN_CENTER);
description.addElement(p);
Seems like you have tried everything but using the approaches that are explained in the documentation ;-)
I have used one parent table that is table_body. One child table that is sub_table(as i would like to place this sub_table inside a PdfPCell in the parent table. ). I want to draw a line when a row is complete for the parent table as per my requirement. But, the issue is bottomborder for the subtable and for the general pdfPcell 'body_cell_bottomBorder' is not getting aligned in a single straight line.
PdfPTable table_body = new PdfPTable(2); // main table
table_body.getDefaultCell().setBorder(Rectangle.NO_BORDER); // set border to none
table_body.setWidthPercentage(100.0f);
table_body.setWidths(new float[] {3.0f,1.0f,});
table_body.setSpacingBefore(6);
PdfPTable sub_table = new PdfPTable(1); // sub table
sub_table.getDefaultCell().setBorder(Rectangle.NO_BORDER); // set border to none
body_cell_bottomBorder.setPhrase(new Phrase("Example",font_body)); // this cell has the bottom border only
Image image = Image.getInstance(BarCode.createBarcode("example"));
body_cell = new PdfPCell(image, true); // this cell has no border at all
body_cell.setBorder(Rectangle.NO_BORDER);
sub_table.addCell(body_cell); // added one row in the sub table
sub_table.addCell(body_cell_bottomBorder); // added second row in the sub table and also want a bottom border
table_body.addCell(sub_table); // added subtable into the parent table pdfpcell
body_cell_bottomBorder.setPhrase(new Phrase(RPL,font_body)); // now adding second column value in parent table pdfPcell and want a bottom border only
table_body.addCell(body_cell_bottomBorder); // added to the parent table
Problem is these two cells of parent table do not make a complete single straight line which i want.
One way:
In the 'child' PdfPTable as each PdfPCell is added, explicitly set Rectangle.NO_BORDER.
When you're done with the 'child' table, wrap in a PdfPCell and set border(s), then add to 'parent' PdfPTable.
Example in C#, since this question is tagged w/itextsharp:
string text = "0000";
int topBottomBorder = Rectangle.BOTTOM_BORDER | Rectangle.TOP_BORDER;
using (Document document = new Document()) {
PdfWriter writer = PdfWriter.GetInstance(document, STREAM);
document.Open();
PdfPTable parentTable = new PdfPTable(2);
PdfPCell cell = new PdfPCell() {
Phrase = new Phrase(text), Border = topBottomBorder
};
parentTable.AddCell(cell);
// in 'child' PdfPTable *ALL* PdfPCells set *WITH NO* border
PdfPTable childTable = new PdfPTable(1);
childTable.AddCell(new PdfPCell
(
(new BarcodeQRCode(text, 1, 1, null)).GetImage()
)
{ Border = Rectangle.NO_BORDER, PaddingTop = 1 }
);
childTable.AddCell(new PdfPCell() { // row 2
Border = Rectangle.NO_BORDER, Phrase = new Phrase(text)
});
// 1. wrap childTable in PdfPCell and set top & bottom borders
PdfPCell childTableCell = new PdfPCell(childTable) {
Border = topBottomBorder
};
// 2. add to main PdfPTable
parentTable.AddCell(childTableCell);
document.Add(parentTable);
}
Result:
I am using com.lowagie.text to create PDF in my code. All is working fine except I am trying to align my cell content vertically. I want cell text to be in the middle of the cell height.
This is my code
PdfPCell cell = new PdfPCell(new Phrase(value, fontValueNew));
cell.setBorder(o);
cell.setBackgroundColor(new Color(233,232,232));
cell.setHorizontalAlignment(Element.ALIGN_LEFT);
cell.setVerticalAlignment(Element.ALIGN_MIDDLE);
Here ,horizontal alignment is working fine but vertical alignment is not effective.
I'm not too sure as to why, but this works for me (vertical center alignment):
String headingLabel = "Test";
Paragraph heading = new Paragraph(headingLabel,
new Font(helvetica, 28, Font.NORMAL, new BaseColor(0, 0, 0)));
Float textWidth = ColumnText.getWidth(heading);
Float maxAllowed = 630f;
while (maxAllowed < textWidth) {
fontSize -= 2;
heading = new Paragraph(headingLabel,
new Font(helvetica, fontSize, Font.NORMAL, new BaseColor(0, 0, 0)));
textWidth = ColumnText.getWidth(heading);
}
heading.setAlignment(Element.ALIGN_CENTER);
PdfPCell titleCell = new PdfPCell();
titleCell.setHorizontalAlignment(Element.ALIGN_CENTER);
titleCell.setVerticalAlignment(Element.ALIGN_TOP);
titleCell.addElement(heading);
titleCell.setFixedHeight(65f);
headerTable.addCell(titleCell);
ALIGN_MIDDLE has integer value 5 defined in the the iText code. Please pay attention while you are writing ALIGN_MIDDLE a tip comes up "Possible value for vertical element." It means if your element is in vertical orientation then it will work as it calculates the center of the element. My suggestion is to replace ALIGN_MIDDLE with ALIGN_CENTER so your code will look like:
cell.setVerticalAlignment(Element.ALIGN_CENTER);
Try this:
PdfPCell cell = new PdfPCell(new Phrase(value, fontValueNew));
cell.setBorder(o);
cell.setBackgroundColor(new Color(233,232,232));
cell.setHorizontalAlignment(Element.ALIGN_LEFT);
cell.setVerticalAlignment(Element.ALIGN_CENTER);
Working with iText and using table cells.
I have 25 cells (columns) in a table.
The content of each column is rotated 90 degree and is required to be fitted to the height of each cell.
In some cases when the length of the content exceeds the height of the cell, not all the content is visible (Only the part of content is visible that is fitted to the height of the cell, the rest is dropped). I want to get that dropped content and want to show it in the next adjacent cell.
The following code is used -
PdfPCell cell;
for(int i = 0;i< 25;i++)
{
if(locs.get(i) == null)
{
cell = new PdfPCell();
cell.setBorder(0);
table.addCell(cell);
}
else
{
Font font = new Font(FontFamily.HELVETICA, 9, Font.BOLD, BaseColor.BLACK);
cell = new PdfPCell(new Phrase(locs.get(i), font));
cell.setRotation(90);
cell.setBorder(0);
cell.setFixedHeight(110f);
//cell.setMinimumHeight(10f);
table.addCell(cell);
}
}
So if the value of locs.get(i) is greater then the height of the cell (cell height is fixed to 110f in the above code), some content that doesn't fit gets dropped to be shown in the view.
How to get that content and show it to the adjacent cell ?
The method used that solved the purpose is the following:
PdfPCell cell;
for(int i = 0;i< 25;i++)
{
if(locs.get(i) != null)
{
Font font = new Font(FontFamily.HELVETICA, 9, Font.BOLD, BaseColor.BLACK);
cell = new PdfPCell(new Phrase(locs.get(i), font));
cell.setRotation(90);
cell.setBorder(0);
cell.setFixedHeight(110f);
cell.setColspan(2);
table.addCell(cell);
}
else
{
cell = new PdfPCell();
cell.setBorder(0);
table.addCell(cell);
}
}
So setting the colspan to 2 ensures that if the contents exceeds the length of the first column then move the remaining contents to the next column of the cell (One cell having two columns now after adding the colspan of 2).
If anyone knows the better way to do the same thing then you are welcome!
