Error on use copied TiffFrame

Aspose.Imaging Product Family
#1

Hi.
We use TiffFrame.CopyFrame method to join several tiff to one tiff.
It was working with Aspose.Imaging v19.11 and not working with new versions.
When we call TiffImage.Save (the last line in example) error “Internal buffer is empty” occurs.

Example:

private static void BufferError()
{
  const string filename = "in.tiff";
  TiffFrame copiedFrame;

  // prepare test data
  using (var image = new TiffImage(new TiffFrame(new TiffOptions(TiffExpectedFormat.Default), 100, 100)))
    image.Save(filename);

  // do test
  using (var image = (TiffImage)Image.Load(filename))
  {
    copiedFrame = TiffFrame.CopyFrame(image.Frames[0]);
    copiedFrame.CacheData();
  }
  // error internal buffer is empty
  new TiffImage(copiedFrame).Save("out.tiff");
}

I regret to share that at present the issue is still unresolved. We request for your patience and will share the feedback with you as soon as it will be fixed.

I can add that problem occurs when “source” is disposed (stream, image, etc…).

In this example when you perform Save inside last using block (var image…) all is fine.

@Marcin_Lis

Can you please try using following sample code as you need to save inside using block.

private static void BufferError()
{
  const string filename = "in.tiff";
  TiffFrame copiedFrame;

  // prepare test data
  using (var image = new TiffImage(new TiffFrame(new TiffOptions(TiffExpectedFormat.Default), 100, 100)))
    image.Save(filename);

  // do test
  using (var image = (TiffImage)Image.Load(filename))
  {
    copiedFrame = TiffFrame.CopyFrame(image.Frames[0]);
    copiedFrame.CacheData();
    new TiffImage(copiedFrame).Save("out.tiff");
  }
 }
