尝试绘制字符串然后通过 Amyuni Printer 将其打印为 PDF 时出现以下问题:
在按下 (Ctrl+A) 时无法选择文本的地方,我需要此 PDF 文件将其用于另一个 PDF 阅读器,并且似乎阅读器试图阅读所选区域而不是实际文本区域。
我正在使用以下代码来执行此操作:
Font printFont = new Font("Simplified Arabic Fixed", (float)11, FontStyle.Regular);
StreamReader Printfile;
using (StreamReader Printfile = new StreamReader(@"C:\20_2.txt", Encoding.Default))
{
try
{
PrintDocument docToPrint = new PrintDocument();
PaperSize ps = new PaperSize("A4", 827, 1169);
bool bolFirstPage = true;
docToPrint.DefaultPageSettings.PaperSize = ps;
docToPrint.DefaultPageSettings.Landscape = true;
docToPrint.DocumentName = "docName" + DateTime.Now.Ticks.ToString(); //Name that appears in the printer queue
string FirstLine = Printfile.ReadLine();
bool bIsArabic = true;
docToPrint.PrintPage += (s, ev) =>
{
float nFontHight = printFont.GetHeight(ev.Graphics);
bIsArabic = true;
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = 1008;
float topMargin = 120;
string line = null;
//Calculate the number of lines per page.
linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics) + 2;
Image img = Image.FromFile(@"C:\image.bmp");
ev.Graphics.DrawImage(img, 6, 1, 1095, 728);
//***Image Reslution is Working good -->***
StringFormat format = new StringFormat()/*arabic*/;
line = Printfile.ReadLine();
format = new StringFormat(StringFormatFlags.DisplayFormatControl | StringFormatFlags.DirectionRightToLeft)/*arabic*/;
do
{
yPos = topMargin + ((count) * printFont.GetHeight(ev.Graphics) * (float)0.91);
line = " تجربة تجربة تجربة تجربة تجربة";
ev.Graphics.DrawString(line, printFont, Brushes.DeepPink, leftMargin, yPos, format);
count++;
} while ((line = Printfile.ReadLine()) != null && !line.Contains(''));// lines contains \0 as UniCode
// If more lines exist, print another page.
if (line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
};
docToPrint.Print();
}
catch (System.Exception f)
{
MessageBox.Show(f.Message);
}
}
}
当我使用另一种字体类型(如“Arial”)时,我可以选择接近 90% 的文本,但不幸的是,我只能使用“Simplified Arabic Fixed”字体类型,而且我使用的是 Windows Server 2003。
还有一件事,当我尝试从记事本直接打印阿拉伯语文本时,它工作正常。
