已删除API:

  • 无

用法示例:

PSDNET-1755. 在psd文件预览中处理半透明错误

// 在psd文件预览中处理半透明错误。
// BackgroundContents赋值为白色。 透明区域应为白色。

string sourceFile = Path.Combine(baseFolder, "frog_nosymb.psd");
string outputFile = Path.Combine(outputFolder, "frog_nosymb_backgroundcontents_output.psd");

using (PsdImage psdImage = (PsdImage)Image.Load(sourceFile))
{
    RawColor backgroundColor = new RawColor(PixelDataFormat.Rgb32Bpp);
    int argbValue = 255 << 24 | 255 << 16 | 255 << 8 | 255;
    backgroundColor.SetAsInt(argbValue); // 白色

    PsdOptions psdOptions = new PsdOptions(psdImage)
    {
        ColorMode = ColorModes.Rgb,
        CompressionMethod = CompressionMethod.RLE,
        ChannelsCount = 4,
        BackgroundContents = backgroundColor,
    };

    psdImage.Save(outputFile, psdOptions);
}

PSDNET-1897. [AI格式] 添加对含有EPSF标头的AI文件的处理支持

string sourceFile = Path.Combine(baseFolder, "example.ai");
string outputFilePath = Path.Combine(outputFolder, "example.png");

void AssertAreEqual(object expected, object actual)
{
    if (!object.Equals(expected, actual))
    {
        throw new Exception("对象不相等。");
    }
}

using (AiImage image = (AiImage)Image.Load(sourceFile))
{
    AssertAreEqual(image.Layers.Length, 2);
    AssertAreEqual(image.Layers[0].HasMultiLayerMasks, false);
    AssertAreEqual(image.Layers[0].ColorIndex, -1);
    AssertAreEqual(image.Layers[1].HasMultiLayerMasks, false);
    AssertAreEqual(image.Layers[1].ColorIndex, -1);

    image.Save(outputFilePath, new PngOptions());
}

PSDNET-1942. 形状图层渲染部分不正确

string sourceFile = Path.Combine(baseFolder, "ShapeLayerTest.psd");
string outputFile = Path.Combine(outputFolder, "ShapeLayerTest_output.psd");
const int ImgToPsdRatio = 256 * 65535;

PSDNET-1957. 保存文件大小超过200MB且尺寸较大的PSD文件时抛出异常

string sourceFile = Path.Combine(baseFolder, "bigfile.psd");
string outputFile = Path.Combine(outputFolder, "output_raw.psd");

PsdLoadOptions loadOptions = new PsdLoadOptions()

PSDNET-1998. 从23.7升级到24.3后，在将图像保存为PDF时出现保存失败的异常

string sourceFile = Path.Combine(baseFolder, "CVFlor.psd");

using (var psdImage = (PsdImage)Image.Load(sourceFile))

    psdImage.Save(outputFile, saveOptions);
}

PSDNET-2033. 修复获取中文字体信息记录方法中的问题

var fontFolder = Path.Combine(baseFolder, "Font");
string sourceFile = Path.Combine(baseFolder, "bd-worlds-best-pink.psd");

PsdLoadOptions psdLoadOptions = new PsdLoadOptions();
psdLoadOptions.LoadEffectsResource = true;
psdLoadOptions.AllowWarpRepaint = true;
try

    FontSettings.SetFontsFolders(new string[] { fontFolder }, true);
    FontSettings.UpdateFonts();

    using (PsdImage image = (PsdImage)PsdImage.Load(sourceFile, psdLoadOptions))
    {
        foreach (var layer in image.Layers)
        {
            var textLayer = layer as TextLayer;

            if (textLayer != null)
            {
                if (textLayer.Text == "best")
                {
                    // 没有此修复，将会由于中文字体而抛出异常。
                    textLayer.UpdateText("成功");
                }
            }
