.jpgs插件vs Photoshop gif:从包含一系列gif的文件夹中制作动画gif

Question

客户给了我一个FTP访问，在那里他上传了15张图片(按顺序编号)每个产品。

问题1:有没有人知道Wordpress中有没有可能生成动画gif或通过插件？

问题2:如果没有这样的插件，我将不得不在Photoshop中创建动画gif。我尝试将脚本“加载文件到堆栈”，然后运行一个操作的组合，但这仍然是非常手动的工作。我不熟悉脚本，但也许有人已经用脚本做过类似的工作？

谢谢，米里亚姆

Answer 1

您可以在命令行中使用ImageMagick自动完成此操作，而不需要Photoshop。ImageMagick已经安装在大多数Linux发行版上，并且可以在OSX (最好是通过homebrew )和Windows上使用。

假设你的客户给了你以下37帧，这里所有的画面都被安排成一个大的蒙太奇：

​

​

然后，您可以将它们一起放入一个动画GIF中，在命令行中，两帧之间有10厘米的延迟，如下所示：

convert -delay 10 frame* result.gif

要获得以下信息：

Answer 2

jpgYup，使用ImageMagick会更简单--下面的脚本就行了。我已经为每个帧的持续时间添加了一秒，可以在脚本的optionals部分中调整，就在顶部。该脚本还必须保存出来的PSD创建，然后使用保存为web创建的动画gif。

在这里，ImageMagic是您的明确选择。

// *** MUST HAVE ANIMATION WINDOW OPEN
// *** SCRIPT WON'T WORK OTHERWISE!

//OPTIONALS
var frameTime = 1.0;
var tempName = "temp"; // file name for psd

//pref pixels
app.preferences.rulerUnits = Units.PIXELS;

var baseDocCreated = false;
var baseImage = "";


var inFolder = Folder.selectDialog("Please select folder to process");
if (inFolder != null)
{
  var fileList = inFolder.getFiles(/\.(jpg)$/i);
}

var exportpath = inFolder;
//alert(inFolder)

// main loop starts here
for(var a = 0 ;a < fileList.length; a++)
{
  // load the frames one by one
  var doc = open(fileList[a]);

  var tempImage = app.activeDocument.name
  // alert(tempImage)

  //create the base document to work with
  if (baseDocCreated == false)
  {
    imageW = app.activeDocument.width.value;
    imageH = app.activeDocument.height.value;
    imageRes = 72;
    imageName = "baseDoc";
    createNewDocument(imageW, imageH, imageRes, imageName)
  }


  var moveTo = app.documents.getByName(baseImage);
  var moveFrom = app.documents.getByName(tempImage);
  moveImage(moveTo, moveFrom)

  //close without saving
  app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);

  var rename = tempImage.substring(0, tempImage.length -4);
  app.activeDocument.activeLayer.name = rename
  // alert(app.activeDocument.activeLayer.name)

// now deal with the creation
// of the animated gif
var myPSD = exportpath + "\\" + tempName + ".psd";

// call the source document
var srcDoc = app.activeDocument;

var numOfLayers = srcDoc.layers.length;
srcDoc.layers[numOfLayers-1].remove();

// save the psd
psdIt(myPSD);

// get the file path
var filePath = srcDoc.path;

// create animation frames
createAnimationFromLayers();

// set frame timing
setFrameDuration(frameTime);
