When creating a FILE_CCITT_GROUP3_1DIM , is the DPI in the header defaulted?  I am creating the new image with the code below and then taking two other images and combining them onto the new one.  The header has a DPI of 150.  I expected and needed it to be 200.

Create the LBitmap

lReturn = bmpOut.Create( lWidth, lHeight * 2L, lBitsPerPixel );

Saving the LBitmap - lImageType = 27(FILE_CCITT_GROUP3_1DIM )

bmpOut.Save( lImageType, lBitsPerPixel, QS );

Hello,

You can change the resolution of the image before saving it by using the LBitmapBase::SetXResolution and LBitmapBase::SetYResolution methods.

The following code shows how to set the resolution of the image to 200 DPI before saving it:
+-------+
L_INT LBitmapBase__SetXResolutionExample(LBitmapBase& Bitmap)
{
if(Bitmap.GetXResolution()<200)
Bitmap.SetXResolution(200);
if(Bitmap.GetYResolution()<200)
Bitmap.SetYResolution(200);

Bitmap.SetFileName(TEXT("c:\\tif.tif"));
Bitmap.Save(FILE_CCITT_GROUP3_1DIM, 1, 0, NULL);

return SUCCESS;
}
+-------+

Thanks,
