书接上回：【Unity编辑器扩展】(二)PSD转UGUI Prefab, 图层解析和碎图导出_psd导入unity_TopGames的博客-CSDN博客
先上总结：
工具包含的功能：
1. 支持UGUI和TextMeshProGUI并新增FillColor(纯色)共16种UI类型：
Button、TMP Button、 Dropdown、TMP Dropdown、FillColor、Image、InputField、TMP InputField、Mask、RawImage、Scroll View、Slider、Text、TMP Text、Toggle、TMP Toggle。
2. 支持自定义UI类型匹配词，支持扩展自定义解析器Helper，易扩展。
3. 支持批量导出图片和单独导出某个图层图片，美术仅提供psd，无需切图。
4. 支持自动同步UI元素位置和文本字体、字号、行列间距、字体颜色。解放繁琐的手动调节流程。
5. 自动根据UI类型导出图片为Sprite、Texture2D类型，并支持选择导出后是否压缩图片，若UI需要9宫拉伸自动对Sprite设置9宫边界。
6. 支持编辑(手动调节层级或UI类型)，如果UI设计师有遗漏标记类型，程序可手动点选类型，类型刷新后工具自动绑定UI元素。
7. 支持编辑阶段预览psd图层、组。
8. 支持任意UI类型嵌套组合，psd图层层级导出为UI预制体后保持一致。
Aspose.PSD库虽然很强大，但它毕竟是脱离PS的独立解析库，对于PS的有些功能支持并不完善，比如图层特效(如描边、浮雕、阴影等)，把单个图层转换为图片图层的特效会丢失。对于文本图层，转换为图片后会有字体样式改变的问题。比如PS文本用的是宋体字体，转换为图片后变成了默认的雅黑字体。
好在Aspose.PSD支持半个PS智能对象，为什么说是半个，因为Aspose.PSD完美支持PS智能对象图层，但是，通过Aspose.PSD把带有特效的PS图层转换为智能对象后会丢失图层特效。
为了解决这一问题，不得不对之前的设计做出让步，写一个自动转换图层为智能对象的PS脚本，以避免设计师手动转换会有遗漏。UI设计师交付psd前通过脚本自动把所有文本图层和带有特效的图层转换为智能对象。这样才能绕过Aspose.PSD导出图片丢失图层特效的问题。
尽管有了使用PS脚本这个小瑕疵，但相比让UI设计师单独切图并手动标识各个切图位置大小、字体字号颜色等，他们仍然觉得这是一个巨大的解放。同样，对于技术来说，也节省大量时间。即使设计师遗漏了UI类型标记，也可以通过下拉框选择图层的UI类型，仅需简单标记类型就可以一键生成UI预制体。
Aspose.PSD仍在每月一个版本更新迭代，期待功能完善，摆脱所有瑕疵。
PSD转UGUI功能/工作流及原理:
一、PSD规范要求(UI设计师)
由于UI大多属于复合型UI(如上图)，即由多种UI元素类型组合而成。例如，Dropdown(下拉菜单)，主要由下拉框+下拉列表+下拉列表Item三个主体组成，而三个主体又是由其他多个UI元素组成。
UI是由一个或多个UI元素构成，因此多个元素之间必须有父子节点的关系。而PS图层中没有这种关系，只能通过组(Group)把多个图层包起来，而组本身是一个空图层。
例如一个Button，通常包含一个背景图和一个按钮文本。图层结构如下：
实际上UI设计师原本也是需要用组来管理图层和切图的，这一规范并不是问题。主要是UI类型标记，通过对图层命名以".类型"，工具通过对图层类型的识别以及每种UI有单独的解析Helper，最大程度上智能判定识别UI元素类型，对于无迹可寻的元素仍然需要设计师手动标记UI类型。
例如Button解析器(ButtonHelper), 会依次按类型查找图层, 可以最大化放宽对图层标记类型：
buttonBackground = LayerNode.FindSubLayerNode(GUIType.Background, GUIType.Image, GUIType.RawImage);
buttonText = LayerNode.FindSubLayerNode(GUIType.Button_Text, GUIType.Text, GUIType.TMPText);二、解析规则配置
支持配置文本图层和非文本图层的默认类型，例如文本图层默认识别为Text或TextMeshProGUI类型，普通图层默认识别为Image或RawImage类型。
UI Type: 主UI类型和子UI类型。支持的类型如下：
UIPrefab: UI模板预制体。
TypeMatches：UI类型匹配名, 例如Button的匹配项有.bt，.btn，.button。图层名以这些字符结尾就会被识别为Button。
UIHelper: UI的解析逻辑。不同的UI通过重写解析方法对UI元素和对应PS图层进行绑定，以及生成最终的UI GameObject。
Comment：注释说明，用于一键导出说明文档给UI设计师参考。
总的来说，规则配置文件是为了更灵活宽松，可以自由自定义多个UI类型的别名。
以下是一键导出的文档内容：
使用说明:
单元素UI：即单个图层的UI，如Image、Text、单图Button，可以直接在图层命名结尾加上".类型"来标记UI类型。
如"A.btn"表示按钮。
多元素UI: 对于多个图片组成的复合型UI，可以通过使用"组"包裹多个UI元素。在“组”命名结尾加上".类型"来标记UI类型。
组里的图层命名后夹".类型"来标记为UI子元素类型。
各种UI类型支持任意组合：如一个组类型标记为Button，组内包含一个按钮背景图层，一个艺术字图层(非文本图层)，就可以组成一个按钮内带有艺术字图片的按钮。UI类型标识: 图层/组命名以'.类型'结尾

#endif三、PS脚本编写，一键转换特效图层/文本图层为智能对象
为了辅助UI设计师，避免手动转换智能对象会有遗漏，设计师交付PSD文件前需要执行自动化脚本，把特效图层/字体转为智能对象，这样即使不同设备字库丢失也能保持字体原本样式。PS脚本是用js语言编写，没有代码提示是最大的障碍。好在没有复杂逻辑，只是遍历当前打开的psd文档图层，判断图层是否带有特效或是否为文本图层，把符合条件的图层转换为智能对象:
// 判断图层是否包含特效
function hasLayerEffect(layer) {
app.activeDocument.activeLayer = layer;
var hasEffect = false;
try {
var ref = new ActionReference();
var keyLayerEffects = app.charIDToTypeID( 'Lefx' );
ref.putProperty( app.charIDToTypeID( 'Prpr' ), keyLayerEffects );
ref.putEnumerated( app.charIDToTypeID( 'Lyr ' ), app.charIDToTypeID( 'Ordn' ), app.charIDToTypeID( 'Trgt' ) );
var desc = executeActionGet( ref );
if ( desc.hasKey( keyLayerEffects ) ) {
hasEffect = true;
}
}catch(e) {
hasEffect = false;
}
return hasEffect;
}
function convertLayersToSmartObjects(layers)
{
for (var i = layers.length - 1; i >= 0; i--)
{
var layer = layers[i];
if (layer.typename === "LayerSet")
{
convertLayersToSmartObjects(layer.layers); // Recursively convert layers in layer sets
}
else
{
if (hasLayerEffect(layer)){
if(layer.kind === LayerKind.TEXT)convertToSmartObject(layer); // Convert layers with layer effects to smart objects
else layer.rasterize(RasterizeType.SHAPE);
}
}
}
}
// 把图层转换为智能对象，功能等同右键图层->转为智能对象
function convertToSmartObject(layer) {
app.activeDocument.activeLayer = layer;
// 创建一个新的智能对象
var idnewPlacedLayer = stringIDToTypeID("newPlacedLayer");
executeAction(idnewPlacedLayer, undefined, DialogModes.NO);
}
// 导出处理后的PSD文件
function exportPSD() {
var doc = app.activeDocument;
var savePath = Folder.selectDialog("选择psd导出路径");
if (savePath != null) {
var saveOptions = new PhotoshopSaveOptions();
saveOptions.embedColorProfile = true;
saveOptions.alphaChannels = true;
var saveFile = new File(savePath + "/" + doc.name);
doc.saveAs(saveFile, saveOptions, true, Extension.LOWERCASE);
alert("PSD已成功导出!");
}
}
function convertAndExport(){
convertLayersToSmartObjects (app.activeDocument.layers);
//exportPSD();
}
app.activeDocument.suspendHistory("Convert2SmartObject", "convertAndExport();");
//~ convertLayersToSmartObjects (app.activeDocument.layers);
四、Psd转UGUI编辑器
1. Unity中右键PSD文件把PS图层转换成节点，每个节点绑定一个对应图层。
2. 解析UI设计师为UI标记的类型，自动标识图层是否需要导出，自动绑定UI子元素。
3. 查漏补缺，对于没有标记类型并且没有正确识别绑定的UI元素进行手动选择类型。
编辑器根节点提供各项持久化保存设置，并且支持自动压缩图片。压缩方法可参考之前写过的压缩工具:【Unity编辑器扩展】包体优化神器,图片压缩,批量生成图集/图集变体,动画压缩_unity 图片压缩_TopGames的博客-CSDN博客
4. 解析psd图层：重新解析psd为节点树状图。
5. 导出Images：把编辑器下勾选的图层节点导出为图片资源。
6. 生成UIForm：把当前的节点树解析生成为UI界面预制体。

#endif自动把ps图层导出为Sprite资源，若Image为Sliced模式则自动计算并设置Sprite 9宫边界：

var rawReadable = spImpt.isReadable;
if (!rawReadable)

}
}
return null;
}根据图片的Alpha通道计算出9宫边界，通常设置9宫边界还会考虑图片纹理因素，但程序难以智能识别，这里自动9宫只是适用于普通情况，还需要根据实际效果进行手动调整：
/// <summary>
/// 自动计算贴图的 9宫 Border

int width = texture.width;
int height = texture.height;
Color32[] pixels = texture.GetPixels32();
int minX = width;
int minY = height;
int maxX = 0;
int maxY = 0;
// 寻找不透明像素的最小和最大边界
for (int y = 0; y < height; y++)
{
for (int x = 0; x < width; x++)
{
int pixelIndex = y * width + x;
Color32 pixel = pixels[pixelIndex];
if (pixel.a >= alphaThreshold)
{
minX = Mathf.Min(minX, x);
minY = Mathf.Min(minY, y);
maxX = Mathf.Max(maxX, x);
maxY = Mathf.Max(maxY, y);
}
}
}
// 计算最优的borderSize
int borderSizeX = (maxX - minX) / 3;
int borderSizeY = (maxY - minY) / 3;
int borderSize = Mathf.Min(borderSizeX, borderSizeY);
// 根据边界和Border Size计算Nine Slice Border
int left = minX + borderSize;
int right = maxX - borderSize;
int top = minY + borderSize;
int bottom = maxY - borderSize;
// 确保边界在纹理范围内
left = Mathf.Clamp(left, 0, width - 1);
right = Mathf.Clamp(right, 0, width - 1);
top = Mathf.Clamp(top, 0, height - 1);
bottom = Mathf.Clamp(bottom, 0, height - 1);
return new Vector4(left, top, width - right, height - bottom);
}3. Dropdown解析器，对于多种元素组成的复合型、嵌套型UI，可以很好的支持，并且可以任意嵌套组合，没有限制和约束。例如Dropdown内包含了一个ScrollView和一个Toggle类型的Item，就可以直接用ScrollView Helper和Toggle Helper分别对其解析：
#if UNITY_EDITOR
using UnityEngine;
using UnityEngine.UI;
namespace UGF.EditorTools.Psd2UGUI
{
[DisallowMultipleComponent]
public class DropdownHelper : UIHelperBase
{
[SerializeField] PsdLayerNode background;
[SerializeField] PsdLayerNode label;
[SerializeField] PsdLayerNode arrow;
[SerializeField] PsdLayerNode scrollView;
[SerializeField] PsdLayerNode toggleItem;
public override PsdLayerNode[] GetDependencies()
{
return CalculateDependencies(background, label, arrow, scrollView, toggleItem);
}
public override void ParseAndAttachUIElements()
{
background = LayerNode.FindSubLayerNode(GUIType.Background, GUIType.Image, GUIType.RawImage);
label = LayerNode.FindSubLayerNode(GUIType.Dropdown_Label, GUIType.Text, GUIType.TMPText);
arrow = LayerNode.FindSubLayerNode(GUIType.Dropdown_Arrow);
scrollView = LayerNode.FindSubLayerNode(GUIType.ScrollView);
toggleItem = LayerNode.FindSubLayerNode(GUIType.Toggle);
}
protected override void InitUIElements(GameObject uiRoot)
{
var dpd = uiRoot.GetComponent<Dropdown>();
UGUIParser.SetRectTransform(background, dpd);
var bgImg = dpd.targetGraphic as Image;
bgImg.sprite = UGUIParser.LayerNode2Sprite(background, bgImg.type == Image.Type.Sliced) ?? bgImg.sprite;
UGUIParser.SetTextStyle(label, dpd.captionText);
UGUIParser.SetRectTransform(label, dpd.captionText);
var arrowImg = dpd.transform.Find("Arrow")?.GetComponent<Image>();
if (arrowImg != null)
{
UGUIParser.SetRectTransform(arrow, arrowImg);
arrowImg.sprite = UGUIParser.LayerNode2Sprite(arrow, arrowImg.type == Image.Type.Sliced);
}
if (scrollView != null)
{
var svTmp = uiRoot.GetComponentInChildren<ScrollRect>(true).GetComponent<RectTransform>();
if (svTmp != null)
{
var sViewGo = scrollView.GetComponent<ScrollViewHelper>()?.CreateUI(svTmp.gameObject);
if (sViewGo != null)
{
var sViewRect = sViewGo.GetComponent<RectTransform>();
UGUIParser.SetRectTransform(scrollView, sViewRect);
sViewRect.anchorMin = Vector2.zero;
sViewRect.anchorMax = new Vector2(1, 0);
sViewRect.anchoredPosition = new Vector2(0, -2);
}
if (toggleItem != null)
{
var itemTmp = dpd.itemText != null ? dpd.itemText.transform.parent : null;
if (itemTmp != null)
{
toggleItem.GetComponent<ToggleHelper>()?.CreateUI(itemTmp.gameObject);
}
}
}
}
}
}
}
#endif实现了每种基础UI元素的解析后就可以任意进行UI元素组合，例如Slider中包含Slider背景和填充条，在Slider中添加一个文本图层，解析出来后就是一个内涵Text文本的Slider进度条，解析前后的节点层级始终保持统一：
由于篇幅原因其它UI类型的解析代码就不贴了，UGUI和TextMeshProGUI共16种UI类型全部完美支持。
最后，附上psd源文件效果图和一键生成的UGUI预制体效果对比图，运行时效果(左)，psd原图(右)：
