TIOParams.ImageCount

Declaration

property ImageCount: integer

Description

Returns the number of pages/frames/images in the current file. Many image file formats can store multiple images, including TIFF, GIF, DICOM, DCX, ICO and cursor.

This property is valid for all file formats (i.e. returning 1 for formats that do not support multiple images). It provides generic access to file specific properties: GIF_ImageCount, TIFF_ImageCount, GIF_ImageCount and MEDIAFILE_FrameCount.

You can use Seek to load/navigate images within the loaded file.

Note: If attached to a TImageEnView with the PDFViewer enabled, ImageCount will return the PageCount

Examples

// Show the number of pages in a TIFF
ImageEnView1.IO.LoadFromFile('C:\input.tif');
iPages := ImageEnView1.IO.Params.ImageCount;
ShowMessage('Page Count: ' + IntToStr(iPages));

// Print all pages of a TIFF
Printer.Title := 'TIFF Pages';
Printer.BeginDoc();
for I := 0 to ImageEnView1.IO.Params.ImageCount - 1 do
begin
  ImageEnView1.IO.Params.ImageIndex := I;
  ImageEnView1.IO.LoadFromFile('C:\input.tif');
  ImageEnView1.IO.PrintImage();
end;
Printer.EndDoc();

// Load a GIF and save each of its pages as a BMP File
ImageEnView1.IO.LoadFromFile('C:\input.gif'); // Load first image to get value for Params.ImageCount
for I := 0 to ImageEnView1.IO.Params.ImageCount - 1 do
begin
  ImageEnView1.IO.Params.ImageIndex := I;
  ImageEnView1.IO.LoadFromFile('C:\input.gif');
  ImageEnView1.IO.SaveToFile( format( 'D:\image_%d.bmp', [ I + 1 ]);
end;
