Question

Answer 1

我在网上搜索了很多可能的解决方案，但其中 100% 都转换为正方形尺寸。所以，我收集了一些并自己解决了这个问题。

将下面的代码保存为 Photoshop \Presets\Scripts 文件夹中的 .jsx 文件。然后，如果要对多个文件使用它，请执行操作。

// get a reference to the current (active) document and store it in a variable named "doc"
doc = app.activeDocument;  

// change the color mode to RGB.  Important for resizing GIFs with indexed colors, to get better results
doc.changeMode(ChangeMode.RGB);  

// these are our values for the END RESULT width and height (in pixels) of our image
var fWidth = 320;
var fHeight = 350;

// do the resizing.  if height > width (portrait-mode) resize based on height.  otherwise, resize based on width
if (doc.height > doc.width) {
    doc.resizeImage(null,UnitValue(fHeight,"px"),null,ResampleMethod.BICUBIC);
}
else {
    doc.resizeImage(UnitValue(fWidth,"px"),null,null,ResampleMethod.BICUBIC);
}

// Makes the default background white
var white = new SolidColor(); 
white.rgb.hexValue = "FFFFFF";
app.backgroundColor = white;

// Convert the canvas size as informed above for the END RESULT
app.activeDocument.resizeCanvas(UnitValue(fWidth,"px"),UnitValue(fHeight,"px"));

// our web export options
var options = new ExportOptionsSaveForWeb();
options.quality = 70;
options.format = SaveDocumentType.JPEG;
options.optimized = true;

var newName = 'web-'+doc.name+'.jpg';

doc.exportDocument(File(doc.path+'/'+newName),ExportType.SAVEFORWEB,options);
