Constructor Details

Img

public Img(double width,
 double height,
 Path src)
    throws IOException

构造图片对象

该构造器不会输入图片进行解析，直接将图片作为资源使用。

Parameters:

width - 图片在页面内的宽度，单位毫米（mm）

height - 图片在页面内的高度，单位毫米（mm）

src - 图片路径（该构造器不会解析图片大小）

Throws:

IOException - 读取异常

Img

@Deprecated
public Img(Path src)
    throws IOException

Deprecated.

Img(double, double, java.nio.file.Path)

创建图片Div

图片宽度和高度以 每 5pix/mm （像素/毫米）的比例转换。

不建议使用该方式构造图片，图片的宽度和高度应该在由调用者手动指定 建议使用Img(double, double, java.nio.file.Path)方法构造

Parameters:

src - 图片路径

Throws:

IOException - 图片解析异常

Method Details

readImage

public static BufferedImage readImage(File imageFile)
                               throws IOException

尝试读取图片文件为 BufferedImage

首先尝试采用RGB读取，如果失败那么将CMYK进行色彩空间转化为RGB。

Parameters:

imageFile - 图片文件

Returns:

BufferedImage

Throws:

IOException - 操作或转换异常

getSrc

public Path getSrc()

setSrc

public Img setSrc(Path src)

split

public Div[] split(double sHeight)

不允许切分

Specified by:

split in interface ElementSplit

Overrides:

split in class Div<Img>

Parameters:

sHeight - 切分高度

Returns:

根据给定空间分割之后的新元素

elementType

public String elementType()

元素类型

关联绘制器：ImgRender

Overrides:

elementType in class Div<Img>

Returns:

Img
