Invalid Parameter Used. at System.Drawing.Image.Save

[Prasad More]

Hello,
I am trying to write a text on Multi-page TIFF image using C# and .NET GDI+. I have written following code to do this. When I execute this code I get "Invalid Parameter User. at System.Drawing.Image.Save" error.

public void addAnnotationStampOnImage()
{
string strStamp = Path.GetFileNameWithoutExtension(_ImageFileName);
Size dSize;
Image iMulti = Image.FromFile(_ImageFileName);
Font Fnt;
string [] FontColor;
FontStyle FntStyle;
float FontSize, LeftPos, TopPos;
string FontName, FontColors;
int intPageCount, intP;
EncoderParameters encParamsCompress, encParamsMulti, encParamsAddFrame, encParamsCloseFrame;
Encoder encCompress, encSave;
encParamsCompress = new EncoderParameters(1);
encParamsMulti = new EncoderParameters(2);
encParamsAddFrame = new EncoderParameters(1);
encParamsCloseFrame = new EncoderParameters(1);
encCompress = new Encoder(Encoder.Compression.Guid);
encSave = new Encoder(Encoder.SaveFlag.Guid);

encParamsCompress.Param[0] = new EncoderParameter(encCompress, (long)EncoderValue.CompressionCCITT4);
encParamsMulti.Param[0] = new EncoderParameter(encSave, (long)EncoderValue.MultiFrame);
encParamsMulti.Param[1] = new EncoderParameter(encCompress, (long)EncoderValue.CompressionCCITT4);
encParamsAddFrame.Param[0] = new EncoderParameter(encSave, (long)EncoderValue.FrameDimensionPage);
encParamsCloseFrame.Param[0] = new EncoderParameter(encSave, (long)EncoderValue.Flush);

FrameDimension oFDimensionM = new FrameDimension(iMulti.FrameDimensionsList[0]);
intPageCount = iMulti.GetFrameCount(oFDimensionM);

dSize = new Size(iMulti.Width, iMulti.Height);

iMulti.SelectActiveFrame(oFDimensionM, 0);
Bitmap iICN = new Bitmap(iMulti, dSize);
Graphics gImage = Graphics.FromImage(iICN);
FontSize = 28F;
FontName = "Microsoft Sans Serif";
FntStyle = FontStyle.Italic;
FontColors = "00,00,00";
FontColor = FontColors.Split(",".ToCharArray());
Fnt = new Font(FontName, FontSize, FntStyle);
TopPos = 10.0F;
LeftPos = 650.0F;
gImage.DrawString(strStamp, Fnt, new SolidBrush(Color.FromArgb(Convert.ToInt32(FontColor[0]), Convert.ToInt32(FontColor[1]), Convert.ToInt32(FontColor[2]))), new PointF(LeftPos, TopPos));
iICN.Save(_ImageFileName.Replace(".", "temp."), GetEncoderInfo("image/tiff"), encParamsCompress);
for (intP = 1; intP < intPageCount; intP++)
{
iMulti.SelectActiveFrame(oFDimensionM, intP);
iICN.SaveAdd(iMulti, encParamsAddFrame);
}
iICN.SaveAdd(encParamsCloseFrame);
iICN.Dispose();
}

If I change the above function to use
iICN.Save(_ImageFileName.Replace(".", "temp."), ImageFormat.Tiff); instead of
iICN.Save(_ImageFileName.Replace(".", "temp."), GetEncoderInfo("image/tiff"), encParamsCompress); then I get the following " a generic error occurred in GDI+. at System.Drawing.Image.SaveAdd.

Please help.

CCITT4 compression only works on 1 bit per pixel fax type files.

I didn't get you. Can you please explain me what do I need to
modify in my program so that it works.

Best Regards,

I usually get that error when the bitmap im trying to save is disposed.

Are you calling Bitmap.dispose anywhere before calling this?

Hi Bob,

I am also getting the same error.

My first frame with Encoder parameter

ep.Param[0] = new EncoderParameter(Encoder.SaveFlag,(long)EncoderValue.
MultiFrame);
ep.Param[1] = new EncoderParameter(Encoder.Compression,(long)System.Drawing.
Imaging.EncoderValue.CompressionCCITT4);

is saved properly but facing the same error when i try to saveadd another
frame with Encoder Param[0] = ep.Param[0]=new EncoderParameter(Encoder.
SaveFlag,(long)EncoderValue.FrameDimensionPage);

and Param[1] same as above...

( written the code referring ur FAQ http://www.bobpowell.net/onebit.htm )

Please reply ...

Thanks..
