I want to change the border bottom color for the tr tag in html table, which convert the pdf using Itextsharp. it is not working properly. By default black color is coming up as a result. Can any one suggest me how to achieve this uanig Itextsharp.
Thanks in Advance.
Kalai.
Try this out.
StyleSheet style = new StyleSheet();
style.LoadTagStyle("tr", "border-bottom-color", "Yellow");
objects = HTMLWorker.ParseToList(new StringReader("YOUR HTML"), style);
for (int k = 0; k < objects.Count; ++k)
{
document.AddElement((IElement)objects[k]);
}

How can i hide text of small slices in pie chart without to remove the text from the legend in the bottom?
I tried to remove the text like this:
if ((yVal < 5F) {
name = "";
} else {
//Add to y values
}
But then the legent text is empty also. so the users can't really know who is this slice.
My solution is to separate the legend texts and the pie chart slices text.
I set the legend (bottom map for each color) text and colors in this way
- In loop for all the contacts:
List<Integer> colors = new ArrayList<>();
List<String> labels = new ArrayList<>();
labels.add(fullName);
colors.add(METRIC_COLORS[index]);
Legend l = chart.getLegend();
l.setCustom(colors, labels);
In addition I added the text of pie-slices:
PieDataSet dataSet = new PieDataSet(yVals1, "");
dataSet.setColors(METRIC_COLORS);
I have a situation like this:
for (PieEntry pieEntry : leastPieEntries){
if(pieEntry.getValue() < 10)
{
pieEntry.setLabel("");
}
}
Tried to loop through all PieEntries but getValue returns the float value instead of percentage value...how did you do it?
My issue with images and iTextSharp is that I want to put a header in and the have the text below that point.
I can display the image and wrap the text but not get it to display below, even when adding New paragraph.
I am assuming there is some command around the aligmnent but I am struggling to find it even when looking at tutorials such as http://www.mikesdotnetting.com/Article/87/iTextSharp-Working-with-images
'Import Image
Dim vImagePath = "C:\sites\images\" & "Logo.jpg"
Dim jpg As Image = Image.GetInstance(vImagePath)
jpg.ScaleToFit(139.0F, 106.0F)
jpg.Alignment = Image.ALIGN_RIGHT Or Image.TEXTWRAP
jpg.IndentationLeft = 7.0F
jpg.SpacingAfter = 9.0F
jpg.BorderWidthTop = 6.0F
jpg.BorderColorTop = Color.WHITE
document.Add(jpg)
'##Main Document Header
Dim tableHeader As New PdfPTable(1) ' Number in brackets is number of columns
tableHeader.DefaultCell.Border = Rectangle.NO_BORDER
Dim phFirst As Phrase = New Phrase("Title", HeaderFont)
tableHeader.AddCell(phFirst)
document.Add(tableHeader)
I would like to find out information about the layout of text in a PdfPCell. I'm aware of BaseFont.getWidthPointKerned(), but I'm looking for more detailed information like:
How many lines would a string need if rendered in a cell of a given width (say, 30pt)? What would the height in points of the PdfPCell be?
Give me the prefix or suffix of a string that fits in a cell of a given width and height. That is, if I have to render the text "Today is a good day to die" in a specific font in a PdfPCell of width 12pt and height 20pt, what portion of the string would fit in the available space?
Where does iText break a given string when asked to render it in a cell of a given width?
This is with regard to iText 2.1.6. Thanks.
iText uses the ColumnText class to render content to a cell. This is explained in my book on page 98-99. This means that, just like with ColumnText, you need to make the distinction between text mode and composite mode.
In any case, ColumnText measures the width of the characters and tests if they fit the available width. If not, the text is split. You can change the split behavior in different ways: by introducing hyphenation or by defining a custom split character.
I've written a small proof of concept to show how you could implement custom "truncation" behavior. See the TruncateTextInCell example.
Instead of adding the content to the cell, I have an empty cell for which I define a cell event. I pass the long text "D2 is a cell with more content than we can fit into the cell." to this event.
In the event, I use a fancy algorithm: I want the text to be truncated in the middle and insert "..." at the place where I truncated the text.
BaseFont bf = BaseFont.createFont();
Font font = new Font(bf, 12);
float availableWidth = position.getWidth();
int contentLength = content.length();
int leftChar = 0;
int rightChar = contentLength - 1;
availableWidth -= bf.getWidthPoint("...", 12);
while (leftChar < contentLength && rightChar != leftChar) {
availableWidth -= bf.getWidthPoint(content.charAt(leftChar), 12);
if (availableWidth > 0)
leftChar++;
else
break;
availableWidth -= bf.getWidthPoint(content.charAt(rightChar), 12);
if (availableWidth > 0)
rightChar--;
else
break;
}
String newContent = content.substring(0, leftChar) + "..." + content.substring(rightChar);
PdfContentByte canvas = canvases[PdfPTable.TEXTCANVAS];
ColumnText ct = new ColumnText(canvas);
ct.setSimpleColumn(position);
ct.addElement(new Paragraph(newContent, font));
ct.go();
As you can see, we get the available width from the position parameter and we check how many characters match, alternating between a character at the start and a character at the end of the content.
The result is shown in the resulting PDF: the content is truncated like this: "D2 is a c... the cell."
Your question about "how many lines" can be solved in a similar way. The ColumnText class has a getLinesWritten() method that gives you that information. You can find more info about positioning a ColumnText object in my answer to your other question: Can I tell iText how to clip text to fit in a cell
For a game that I am currently making, I have a black background with many white dots, which are being used to represent stars. I have no need for the black color however, and I only wish for the stars to show. My question is this: Is it possible to completely hide the black color without using an image manipulation program, that is, using only code? Any help is appreciated.
This is the form:
// some rgba color representation
struct t_rgba {
uint8_t r, g, b, a;
};
bool SetToTransparentIfPixelIsBlack(t_rgba* const rgba) {
// is it black?
if (0 == rgba->r && 0 == rgba->g && 0 == rgba->b) {
// then set the alpha value to transparent:
rgba->a = 0;
}
}
although the image data you are using will be represented differently.
I have a pie chart and I need to change the size of the symbols in the legend, but there's only setSymbolWidth. How do I change the height of the symbol?
I'm using Moxie Group's GWT highchart, but if there's a way in solving this with the javascript highcharts I'm probably able to do it in the GWT version.
I tried this solution http://jsfiddle.net/MEr2n/ but the series property is returning null (don't know why) even after I add a series to the chart. I'm also not sure this would work because it seems this solution gets the SVG element of the legend from the serie and set its property directly, in my case there is one serie and a symbol for each point in the serie.
I solved it. Unfortunately I needed to create a very ugly workaround for this. At least it worked.
My solution was:
NodeList<Element> gElements = chart.getElement().getElementsByTagName('g');
for (int i = 0; i < gElements.getLength(); i++) {
Element gel = gElements.getItem(i);
if (gel.getAttribute("class").equals("highcharts-legend")) {
NodeList<Element> elements = gel.getElementsByTagName("rect");
for (int j = 0; j < elements.getLength(); j++) {
elements.getItem(j).setAttribute("height", "8");
}
break;
}
}
I guess I could have used gwt-jquery to get the g element with the highcharts-legend class, but I don't want to add another API just for this.
