Gif conversion into PNG using Aspose.Imaging for .NET

Aspose.Imaging Product Family
1

Hello, the conversion of a gif file into png (or pdf) creates a strange final image
(see attached original sample gif and a png + pdf conversion)
gif.zip (98.5 KB)

we can’t tell you when, but previous aspose.imaging dll (3.x maybe) was not affected by this bug (our code is unchanged from years)

here is our code:
Aspose.Imaging.ImageOptions.PngOptions OptionsIM = new Aspose.Imaging.ImageOptions.PngOptions();
OptionsIM.ColorType = Aspose.Imaging.FileFormats.Png.PngColorType.TruecolorWithAlpha;
// OptionsIM.TransparentColor = new Aspose.Imaging.TransparentColorSetting(Aspose.Imaging.Color.Transparent);
Aspose.Imaging.ResolutionSetting oResIM = new Aspose.Imaging.ResolutionSetting(Convert.ToDouble(m_iResolution), Convert.ToDouble(m_iResolution));
OptionsIM.ResolutionSettings = oResIM;
((Aspose.Imaging.Image)m_oDocument).Save(_oOutputStream, OptionsIM);

using (Image m_oDocument = Image.Load(path))
{
int m_iResolution = 98;
Aspose.Imaging.ImageOptions.PngOptions OptionsIM = new Aspose.Imaging.ImageOptions.PngOptions();
OptionsIM.ColorType = Aspose.Imaging.FileFormats.Png.PngColorType.TruecolorWithAlpha;
Aspose.Imaging.ResolutionSetting oResIM = new Aspose.Imaging.ResolutionSetting(Convert.ToDouble(m_iResolution), Convert.ToDouble(m_iResolution));
OptionsIM.ResolutionSettings = oResIM;
((Aspose.Imaging.Image)m_oDocument).Save(path + “.png”, OptionsIM);
