i'm using websupergoos abcpdf to convert html pages to pdf via addimageurl.
Works great, but the resulting pdf does not allow the user to select text and copy. All is one 'image'.
Is it possible to do this? Which are the settings to use?
This is my current code. The commented "flatten" does not seem to do anything relevant. The HttpStream simply forewards the pdf to users as a doc.
var doc = new Doc();
doc.HtmlOptions.UseScript = true;
doc.Units = "mm";
doc.MediaBox.String = "0 0 210 297";
doc.Rect.String = doc.MediaBox.String;
doc.Rect.Inset(10.0, 10.0);
doc.SetInfo(0, "License", abcpdfkey);
doc.HtmlOptions.UseScript = true;
doc.HtmlOptions.AddMovies = true;
doc.HtmlOptions.RetryCount = 0;
doc.HtmlOptions.ContentCount = 1;
doc.Page = doc.AddPage();
for (int i = doc.AddImageUrl(url); doc.Chainable(i); i = doc.AddImageToChain(i))
{
doc.Page = doc.AddPage();
}
int pageCount = doc.PageCount;
for (int j = 1; j <= pageCount; j++)
{
doc.PageNumber = j;
// doc.Flatten();
}
this.HttpStream(doc.GetData(), filename);
Before sending the PDF to the HTTP stream, you can set the encryption properties
The CanCopy Property sets if the user can copy text from the PDF
To set it add the following code:
doc.Encryption.CanCopy = true;
You may need to set doc.Encryption.CanExtract as well

ABCpdf is not supported the https images , when we generate the pdf we will get the cross symbols.
Please help me .
Thank You

I have been successful in creating image from PDF using iTextSharp. It creates images equal to number of pages in PDF but generated images does not preview in any image viewer software. It says image is corrupted. Below is the code I have created.
try
{
PdfReader reader = null;
int currentPage = 1;
int pageCount = 0;
string destinationFolderPath = string.Format(#"{0}PageImages\{1}", BaseDataPath, Convert.ToString(documentId));
if (!Directory.Exists(destinationFolderPath))
{
Directory.CreateDirectory(destinationFolderPath);
}
reader = new PdfReader(filePath);
reader.RemoveUnusedObjects();
pageCount = reader.NumberOfPages;
string ext = ".png";
for (int i = 1; i <= pageCount; i++)
{
PdfReader reader1 = new PdfReader(filePath);
string destinationFilePath = string.Format(#"{0}/{1}{2}", destinationFolderPath, Convert.ToString(i), ext);
reader1.RemoveUnusedObjects();
Document doc = new Document(reader1.GetPageSizeWithRotation(currentPage));
PdfCopy pdfCpy = new PdfCopy(doc, new FileStream(destinationFilePath, FileMode.Create));
doc.Open();
for (int j = 1; j <= 1; j++)
{
PdfImportedPage page = pdfCpy.GetImportedPage(reader1, currentPage);
//pdfCpy.SetFullCompression();
pdfCpy.AddPage(page);
currentPage += 1;
}
doc.Close();
pdfCpy.Close();
reader1.Close();
reader.Close();
}
}
catch (Exception ex)
{
throw ex;
}
Could someone please suggest what is wrong here?
Thanks
You are creating a PDF file using PdfCopy, but you are storing that PDF as if you were creating a PNG file:
string ext = ".png";
string destinationFilePath =
string.Format(#"{0}/{1}{2}",
destinationFolderPath, Convert.ToString(i), ext);
PdfCopy pdfCpy = new PdfCopy(doc,
new FileStream(destinationFilePath, FileMode.Create));
You can't open a .png file in a PDF viewer. Your operating system will try to open the file you're creating as if it were an image, but the bytes of that "image" will be PDF bytes and your image viewer won't recognize it.
Change this line:
string ext = ".png";
To this:
string ext = ".pdf";
And you'll be able to open your file in a PDF viewer.
By the way: your code is awkward. For instance. I don't understand why you'd create a look to execute something only once:
for (int j = 1; j <= 1; j++)
Also: if it's your intention to convert PDF pages to PNG, reconsider. iTextSharp doesn't convert PDF to images.
Using C#, which is the best and easiest way to export all the data from a datatable to an excel to get it downloaded?
I use Microsoft Interop.
Here is some sample code to get you started.
There are probably hundreds of tutorials which are better than the below. I have removed much of the code I use so I doubt the following will compile, but with careful reading, and some investigation into tutorials, you should be able to accomplish what you need.
public static void ExportToExcel(DataSet dsTodo, string strPathToSaveFile)
{
try
{
int numSteps = (dsTodo != null ? dsTodo.Tables.Count * 2 : 1);
Microsoft.Office.Interop.Excel.ApplicationClass ExcelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
Workbook xlWorkbook = ExcelApp.Workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
if (dsTodo.Tables.Count > 0)
{
for (int i = dsTodo.Tables.Count; i > 0; i--)
{
Sheets xlSheets = null;
Worksheet xlWorksheet = null;
//Create Excel Sheets
xlSheets = ExcelApp.Sheets;
xlWorksheet = (Worksheet)xlSheets.Add(xlSheets[1], Type.Missing, Type.Missing, Type.Missing);
System.Data.DataTable table = dsTodo.Tables[i - 1];
xlWorksheet.Name = table.TableName;
for (int j = 1; j < table.Columns.Count + 1; j++)
{
ExcelApp.Cells[1, j] = table.Columns[j - 1].ColumnName;
}
var excelData = new object[table.Rows.Count, table.Columns.Count];
for (int rowJ = 0; rowJ < table.Rows.Count; rowJ++)
{
for (int colI = 0; colI < table.Columns.Count; colI++)
{
excelData[rowJ, colI] = table.Rows[rowJ][colI];
}
}
int startCol = 1;
int endCol = startCol + table.Columns.Count - 1;
int startRow = 2;
int endRow = startRow + table.Rows.Count - 1;
string startLoc = GetCellFromCoords(startCol, startRow);
string endLoc = GetCellFromCoords(endCol, endRow);
//ExcelApp.get_Range(startLoc, endLoc).Value2 = excelData;
try
{
Range valRange = ExcelApp.get_Range(startLoc, endLoc);
valRange.Value2 = excelData;
}
I have a problem with charsets.
I parsed a csv file in google-app-engine and I'm posting to an uiapp table.
But I checked special characters like áéíóú and those are not well displayed (?square symbol).
When I was setting up my code I played writing the string imported to a google docs document and it worked the same.
some advice please?
I search for:
a global charset definition to the code. or
string var transformation that makes the chars appear like I want to. (avoiding html &number definitions.
Is this related to the blob object?
The thing is important i come from spain and we need such characters.
app that get's a csv ';' delimited file and shows it's content
I post all my code, it's barely as the tutorial that is given.

};
}

I found it, we need to get the content of the file first with a Blob object.
This function is the one I use to parse some csv info into an array:
function parsedCSV(){
//searching the file. This gets only one file in var origen
var listaArchivos = DocsList.getFolderById('XXXXXXX').getFiles()
for (var i = 0; i < listaArchivos.length; i++) {
if (listaArchivos[i].getName() == 'baul.csv'){
var origen = listaArchivos[i];
};
}
// HERE IS THE GOOD DEFINITION OF CHAR:
var texto2= origen.getBlob().getDataAsString('ISO-8859-1');
// I put all the corrected text in an array
var arra = Utilities.parseCsv(texto2,";");
return(arra);
}
This is the solved thing: https://script.google.com/macros/s/AKfycbyHa-bLWBHBr3qifbvzxecqGgGUYX8mhyo-TKoyfGvy/exec
The trick:
var textVariableName = fileObjectVariableName.getBlob().getDataAsString('ISO-8859-1');
I need to list detailed information about the fonts used in a set of inDesign documents. The information I need is essentially accessible through the menu item Type › Find Fonts… (as explained here) but going through each font in every document and writing down the information is not feasible.
I can find much of the information in the Font objects underdocument.fonts and my question is how to access or generate the extended properties found in the panel below:
Character count for the given font
Pages where the font occurs
Edit: The document.fonts array also doesn't seem to include missing fonts.
Well, here's a brute-force strategy for character counting. It iterates through every character textStyleRange in the document and checks its applied font. Edit: Updated to use textStyleRanges. Much faster than going through every character.
var document = app.open(new File(Folder.desktop.fsName + "/test/test.indd"));
try {
var fontMultiset = countCharsInFonts(document);
// For each font, display its character count.
var fonts = document.fonts.everyItem().getElements();
for (var i = 0; i < fonts.length; i++) {
var fontName = fonts[i].fullName;
$.writeln(fontName + ": " + fontMultiset[fontName]);
}
}
finally {
document.close();
}
function countCharsInFonts(document) {
// Create the font multiset.
var fontMultiset = {
add: function add(fontName, number) {
if (this.hasOwnProperty(fontName)) {
this[fontName] += number;
}
else {
this[fontName] = number;
}
},
};
// For every textStyleRange in the document, add its applied font to the multiset.
var stories = document.stories.everyItem().getElements();
for (var i = 0; i < stories.length; i++) {
var story = stories[i];
var textStyleRanges = story.textStyleRanges.everyItem().getElements();
for (var j = 0; j < textStyleRanges.length; j++) {
fontMultiset.add(textStyleRanges[j].appliedFont.fullName, textStyleRanges[j].length);
}
}
// For any fonts that aren't applied in the document, set the character count to 0.
var fonts = document.fonts.everyItem().getElements();
for (var i = 0; i < fonts.length; i++) {
var fontName = fonts[i].fullName;
if (!fontMultiset.hasOwnProperty(fontName)) {
fontMultiset[fontName] = 0;
}
}
return fontMultiset;
}
