Sample Code: Getting the Page Content Rectangle
The Page class in TX Text Control returns TextBounds covering the full printable area, not just the region containing actual content. This C# method calculates the true content rectangle by combining the page text bounds origin with the bottom coordinate of the last line.
I have just found this code snippet that was provided by our support department to help a user to get a text rectangle of a specific page.
Using TX Text Control's Page class, you can get the page bounds and the text bounds. This, however, is a rectangle of possible text on a page and not the text that has been added to the page. Thankfully, getting the value we want is pretty easy.
The following function returns the actual text of a specific page:
// [C#]
private Rectangle GetPageContentRect(int Page)
{
Graphics g = textControl1.CreateGraphics();
int dpiX = (int)(1440 / g.DpiX);
TXTextControl.Page page = textControl1.GetPages()[Page];
TXTextControl.Line lastLine = textControl1.Lines.GetItem(page.Start +
page.Length - 2);
Rectangle rRect = new Rectangle(page.TextBounds.X / dpiX,
page.TextBounds.Y / dpiX,
page.TextBounds.Width / dpiX,
lastLine.TextBounds.Bottom / dpiX -
page.TextBounds.Top / dpiX);
return rRect;
