VectorShapeTransform.Yx

VectorShapeTransform.Yx property

Hämtar eller ställer in YX-värdet.

public double Yx { get; set; }

Fastighetsvärde

YX-värdet.

Exempel

Följande kod visar möjligheten att ändra storlek på ett formlager som innehåller vektorbanor.

[C#]

string sourceFileName = "vectorShapes.psd";
string outputFileName = "out_vectorShapes.psd";
string sourcePath = sourceFileName;
string outputPath = outputFileName;
string outputPathPng = Path.ChangeExtension(outputPath, ".png");
using (var psdImage = (PsdImage)Image.Load(sourcePath))
{
    foreach (var layer in psdImage.Layers)
    {
        layer.Resize(layer.Width * 5 / 4, layer.Height / 2);
    }

    psdImage.Save(outputPath);
    psdImage.Save(outputPathPng, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
}

Det här exemplet visar hur man får och ställer in nya Transform- och OriginBoxCorners-egenskaper för ShapeOriginSettings i Vogk-resursen för FillLayer i PSD-filen.
