我有一个脚本来调整图像大小。 无论如何让它输出5张图像？

Question

doc = app.activeDocument;  

// these are our values for the END RESULT width and height (in pixels) of our image
var fWidth = 1313;
var fHeight = 1750;

// 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;

// 2012, use it at your own risk;

I want to be able to generate 5 images with 5 different sizes with the same script. Is it just as simple as repeating my code multiple times, or do i need to reset some variables in between?

When I try just duplicating my code and changing the output file name and the sizes, it does it but my canvas size doesn't reset and change based off the current image size. It just keeps getting bigger. Is there anyway to make the canvas size resize based on that current image size?

var sizes = [
{
    width: 1531,
    height: 1948
},
{
    width: 1303,
    height: 1954
},  
{
    width: 1066,
    height: 1909
}
 ];
doc = app.activeDocument;
// looping through all the sizes
for (var i = 0; i < sizes.length; i++)
{
    var cloneDoc = doc.duplicate(); // duplicates current document
    resizeAndSave(sizes[i].width, sizes[i].height); // passes width and height of sizes to function with your code
    cloneDoc.close(SaveOptions.DONOTSAVECHANGES); // closes the clone
    activeDocument = doc; // making sure that foremost document is the original doc
}

function resizeAndSave(fWidth, fHeight)
{
    //your code


// get a reference to the current (active) document and store it in a variable named "doc"




// these are our values for the END RESULT width and height (in pixels) of our image
//var fWidth = 1313;
//var fHeight = 1750;

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

white.rgb.hexValue = "FFFFFF";

Answer 1

You need to reset or clone your original document in the beginning of the each loop. I prefer cloning so I'd do something like this:

// creating array of sizes
var sizes = [
{
    width: 313,
    height: 750
},
{
    width: 413,
    height: 150
}, ];

// looping through all the sizes
for (var i = 0; i < sizes.length; i++)
{
    var cloneDoc = doc.duplicate(); // duplicates current document
    resizeAndSave(sizes[i].width, sizes[i].height); // passes width and height of sizes to function with your code
    cloneDoc.close(SaveOptions.DONOTSAVECHANGES); // closes the clone
    activeDocument = doc; // making sure that foremost document is the original doc
}

function resizeAndSave(fWidth, fHeight)
{
    //your code
};

// get a reference to the current (active) document and store it in a variable named "doc"




// these are our values for the END RESULT width and height (in pixels) of our image

activeDocument = doc;

    doc.resizeImage(null,UnitValue(fHeight,"px"),null,ResampleMethod.BICUBIC);
}
else {
    doc.resizeImage(UnitValue(fWidth,"px"),null,null,ResampleMethod.BICUBIC);
