本文整理了Java中org.eclipse.swt.graphics.Image.getImageData()方法的一些代码示例，展示了Image.getImageData()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Image.getImageData()方法的具体详情如下：
包路径：org.eclipse.swt.graphics.Image
类名称：Image
方法名：getImageData

Image.getImageData介绍

[英]Returns an ImageData based on the receiver. Modifications made to this ImageData will not affect the Image.
[中]基于接收方返回一个ImageData。对此ImageData所做的修改不会影响图像。

代码示例

private void repaint( GC gc, int width, int height ) {
 ImageData imd = image.getImageData();
 double sizeOnPaperX = imd.width * factorx;
 double sizeOnPaperY = imd.height * factory;
 double actualSizeX = sizeOnPaperX * scale / 100;
 double actualSizeY = sizeOnPaperY * scale / 100;
 // What % of the screen is filled?
 // The canvas is nrcols * nrrows nr of pages large.
 double percentScreenX = actualSizeX / ( page.x * nrcols );
 double percentScreenY = actualSizeY / ( page.y * nrrows );
 gc.drawImage(
  image, 0, 0, imd.width, imd.height, 0, 0, (int) ( width * percentScreenX ),
  (int) ( height * percentScreenY ) );
 StringBuilder text = new StringBuilder();
 text.append( nrcols ).append( "x" ).append( nrrows ).append( " @ " ).append( scale ).append( "%" );
 gc.drawText( text.toString(), 0, 0 );
 for ( int c = 1; c < nrcols; c++ ) {
  gc.drawLine( c * ( width / nrcols ), 0, c * ( width / nrcols ), height );
 }
 for ( int r = 1; r < nrrows; r++ ) {
  gc.drawLine( 0, r * ( height / nrrows ), width, r * ( height / nrrows ) );
 }
}
