Hi,
My first question is How to get Font Info from pdf.
and how to create pdf column by column .
Hi Devinder,
Thanks for your inquiry.
In reference to your inquiry, you can get fonts from the Resource collection of the Page object and forms(XObject). Please note that the Page object provides the Resources collection and Resources provide the Fonts collection. Enumerate all pages and then all fonts on the pages. Some fonts may be found in forms (XObjects), so also enumerate all the Forms in the Page.Resources and then enumerate xForm.Resources.Fonts. The XForm may contain another form inside the resources, so it is a recursion. Please check the following code for details.
static void Main(string[] args)
{
Document pdf = new Document(myDir + "test.pdf");
Dictionary<string, string> fontNames = new Dictionary<string, string>();
for (int i = 1; i <= pdf.Pages.Count; i++)
{
foreach (Aspose.Pdf.Text.Font font in pdf.Pages[i].Resources.Fonts)
{
if (!fontNames.ContainsKey(font.FontName))
fontNames.Add(font.FontName, font.FontName);
}
if (pdf.Pages[i].Resources.Forms.Count > 0)
ProcessXForms(pdf.Pages[i].Resources.Forms, fontNames);
}
foreach (string fontName in fontNames.Keys)
{
Console.WriteLine("Font {0} on page resource", fontName);
}
pdf.Dispose();
}
public static void ProcessXForms(Aspose.Pdf.XFormCollection forms, Dictionary<string, string> fontNames)
{
foreach (Aspose.Pdf.XForm form in forms)
{
if (form.Resources.Fonts != null)
{
foreach (Aspose.Pdf.Text.Font font in form.Resources.Fonts)
{
if (!fontNames.ContainsKey(font.FontName))
fontNames.Add(font.FontName, font.FontName);
// recursive call
if (form.Resources.Forms.Count > 0)
ProcessXForms(form.Resources.Forms, fontNames);
}
}
}
}
Regarding your second question about creating a PDF column by column, I am afraid that this feature is not currently supported in the new generator. I have logged a new feature request PDFNEWNET-37950 in our issue tracking system for its implementation. Meanwhile, you may use the old generator (Aspose.Pdf.Generator) to create a PDF with columns. Please check the sample code below. We will notify you as soon as it is supported in the new generator.
Aspose.Pdf.Generator.Pdf pdf = new Aspose.Pdf.Generator.Pdf();
// specify the left margin info for the PDF file
pdf.PageSetup.Margin.Left = new Aspose.Pdf.Generator.MarginInfo().Left = 40;
// specify the Right margin info for the PDF file
pdf.PageSetup.Margin.Right = new Aspose.Pdf.Generator.MarginInfo().Right = 40;
Aspose.Pdf.Generator.Section sec0 = pdf.Sections.Add();
Aspose.Pdf.Generator.Section sec1 = pdf.Sections.Add();
Aspose.Pdf.Generator.Section sec2 = pdf.Sections.Add();
sec0.IsNewPage = false;
sec1.IsNewPage = false;
sec2.IsNewPage = false;
Graph graph1 = new Graph(sec0, 500, 2);
// Add the line to paragraphs collection of section object
sec0.Paragraphs.Add(graph1);
// specify the coordinates for the line
float[] posArr = new float[] { 1, 2, 500, 2 };
Line l1 = new Line(graph1, posArr);
graph1.Shapes.Add(l1);
//Create string variables with text containing html tags
string s = "<font face=\"Times New Roman\" size=18>" + "<strong>How to Steer Clear of money scams</strong> </font>";
//Create text paragraphs containing HTML text
Text heading_text = new Text(s);
heading_text.IsHtmlTagSupported = true;
heading_text.TextInfo.Alignment = Aspose.Pdf.Generator.AlignmentType.Left;
sec0.Paragraphs.Add(heading_text);
// Add four columns in the section
sec1.ColumnInfo.ColumnCount = 2;
// Set the spacing between the columns
sec1.ColumnInfo.ColumnSpacing = "5";
sec1.ColumnInfo.ColumnWidths = "105 105";
Text text1 = new Text("By A Googler (The Official Google Blog)");
text1.TextInfo.FontSize = 8;
text1.TextInfo.LineSpacing = 2;
text1.TextInfo.Alignment = Aspose.Pdf.Generator.AlignmentType.Left;
sec1.Paragraphs.Add(text1);
text1.TextInfo.FontSize = 10;
text1.TextInfo.IsTrueTypeFontItalic = true;
// Create a graphs object to draw a line
Graph graph2 = new Graph(50, 10);
// specify the coordinates for the line
float[] posArr2 = new float[] { 1, 10, 100, 10 };
Line l2 = new Line(graph2, posArr2);
graph2.Shapes.Add(l2);
// Add the line to paragraphs collection of section object
sec1.IsNewColumn = true;
sec1.Paragraphs.Add(graph2);
Text text2 = new Text(@"Sed augue tortor, sodales id, luctus et, pulvinar ut, eros. Suspendisse vel dolor. Sed quam. Curabitur ut massa vitae eros euismod aliquam. Pellentesque sit amet elit.

Hi Divender,
Thanks for your patience. As stated above PDFNEWNET-37950 has been fixed in Aspose.Pdf for .NET 10.3.0. Please note we have fixed the issue in new generator. You need to use FloatingBox paragraph for creating a PDF document with multiple columns. Please find attached code for the purpose. It will help you to accomplish the task.
