flash - AS3使用“打印作业”来打印影片剪辑

Question

我目前正在尝试创建一个函数，该函数将允许我传递MovieClip并进行打印。

这是该函数的简化版本:

function printMovieClip(clip:MovieClip) {

var printJob:PrintJob = new PrintJob();
var numPages:int = 0;
var printY:int = 0;
var printHeight:Number;

if ( printJob.start() ) {

/* Resize movie clip to fit within page width */
if (clip.width > printJob.pageWidth) {
   clip.width = printJob.pageWidth;
   clip.scaleY = clip.scaleX;
}

numPages = Math.ceil(clip.height / printJob.pageHeight);

/* Add pages to print job */
for (var i:int = 0; i < numPages; i++) {
 printJob.addPage(clip, new Rectangle(0, printY, printJob.pageWidth, printJob.pageHeight));
 printY += printJob.pageHeight;
}

/* Send print job to printer */
printJob.send();

/* Delete job from memory */
printJob = null;

}

}

printMovieClip( testMC );

不幸的是，这无法按预期方式工作，即打印MovieClip的整个宽度并在长度上进行分页符。

我忘了缩放打印区域以匹配要调整大小的影片剪辑。请参阅以下工作解决方案:

function printMovieClip(clip:MovieClip) {

    var printJob:PrintJob = new PrintJob();
    var numPages:int = 0;
    var printArea:Rectangle;
    var printHeight:Number;
    var printY:int = 0;

    if ( printJob.start() ) {

        /* Resize movie clip to fit within page width */
        if (clip.width > printJob.pageWidth) {
            clip.width = printJob.pageWidth;
            clip.scaleY = clip.scaleX;
        }

        /* Store reference to print area in a new variable! Will save on scaling calculations later... */
        printArea = new Rectangle(0, 0, printJob.pageWidth/clip.scaleX, printJob.pageHeight/clip.scaleY);

        numPages = Math.ceil(clip.height / printJob.pageHeight);

        /* Add pages to print job */
        for (var i:int = 0; i < numPages; i++) {
            printJob.addPage(clip, printArea);
            printArea.y += printArea.height;
        }

        /* Send print job to printer */
        printJob.send();

        /* Delete job from memory */
        printJob = null;

    }

}

printMovieClip( testMC );
