Do you use PsdReader or PsdProcessor?

You can extract the rotation angle using the Transform property. The transform matrix contains scale, skew and rotate information, so you need to use math to extract the angle.

As for reading line-spacing please refer to the leading value:

I use PsdReader .
I look the Transform property,but I get the value is
IsIdentity false
IsInvertible true
OffsetX 43.7267075
OffsetY 133.208435

Elements[0] 0.8255737
Elements[1] -0.563502848
Elements[2] 0.563502848
Elements[3] 0.8255737
Elements[4] 43.7267075
Elements[5] 133.208435

How can I extract the angle.
And PsdTextFrame has transform.But PsdSmartFrame have not the property. I want to get angle,too.

rot = Math.Atan2( _
pts(1).Y - pts(0).Y, _
pts(1).X - pts(0).X) * 180.0 / Math.PI
I don't konw this. Which PTS corresponds to?


And the leading property corresponds to line height in css? The value of leading property is sometimes wrong. In ps value:72.02, in leading:314.888855

Here is a code sample based on the above VB one:

Code:
using Aurigma.GraphicsMill.Codecs.Psd;
using System;

class Program
{
    static void Main(string[] args)
    {
        using (var psdReader = new PsdReader("../../BusinessCard.psd"))
        {
            for (int i = 0; i < psdReader.Frames.Count; i++)
            {
                var frame = psdReader.Frames[i];

                if (frame.Type == FrameType.Text)
                {
                    var textFrame = (PsdTextFrame)frame;

                    //The original matrix
                    var matrix0 = textFrame.Transform;

                    //Remove translation
                    var matrix1 = new System.Drawing.Drawing2D.Matrix();
                    matrix1.Multiply(matrix0);
                    matrix1.Translate(-matrix0.OffsetX, -matrix0.OffsetY);

                    //Get rotation
                    var points = new System.Drawing.PointF[2];
                    points[0] = new System.Drawing.PointF(0, 0);
                    points[1] = new System.Drawing.PointF(1, 0);
                    matrix1.TransformPoints(points);
                    var rotation = Math.Atan2(points[1].Y - points[0].Y,
                        points[1].X - points[0].X) * 180.0f / Math.PI;

                    Console.WriteLine(rotation);
                }
            }
        }
    }
}


This code outputs the following result for our test image:

Does the leading property corresponds to line height in css? The value of leading property is sometimes wrong. For example:in ps value:72.02, in leading:314.888855

Leading and line-height in CSS are not the same. Leading is a char property while line-height is a property of a line box. However, they are both related to interline distance.

Please post here PSD file with wrong leading, we'll check it.
