Ah, you are drawing a completely transparent bitmap - are you sure your png is black and not transparent (it will look black in some viewers like IrfanView)? |

Can you upload the real svg (not the png image) to be able to reproduce this? |

Ok, I checked your image, and get the same result, though I'm not sure what you want to accomplish with this code. |

Same issue here, can anybody point in the right direction on how to make transparent background turn to white instead of black when saving to PNG? |

Fill white in advance. var size = svgDoc.GetDimensions();
var image = new System.Drawing.Bitmap((int)Math.Round(size.Width), (int)Math.Round(size.Height));
using (var g = System.Drawing.Graphics.FromImage(image))
using (var brush = new System.Drawing.SolidBrush(System.Drawing.Color.White))
{
g.FillRectangle(brush, 0, 0, image.Width, image.Height);
}
svgDoc.Draw(image); |
