Java图像处理库 Sanselan

fmms 13年前

Sanselan 是一个纯 Java 的图形库,可以读写各种格式的图像文件,包括快速解析图片信息例如大小/颜色/icc以及元数据等。尽管因为是Java开发的,在处理速度上会稍微慢一 些,但具备良好的可移植性。虽然尚未发布1.0 版本,但是已经有多个项目在使用 Sanselan 来处理图像文件。

该项目目前还是 Apache 组织的一个孵化项目。

示例代码:

File file = someFile;  BufferedImage image_3 = Sanselan.getBufferedImage(file);  InputStream is = someInputStream;  BufferedImage image_4 = Sanselan.getBufferedImage(is);    // Write an image.  BufferedImage image = someImage;  File dst = someFile;  ImageFormat format = ImageFormat.IMAGE_FORMAT_PNG;  Map optional_params = new Hashtable();  Sanselan.writeImage(image, dst, format, optional_params);    OutputStream os = someOutputStream;  Sanselan.writeImage(image, os, format, optional_params);    // get the image's embedded ICC Profile, if it has one.  byte icc_profile_bytes[] = Sanselan.getICCProfileBytes(imageBytes);    ICC_Profile icc_profile = Sanselan.getICCProfile(imageBytes);    // get the image's width and height.  Dimension d = Sanselan.getImageSize(imageBytes);    // get all of the image's info (ie. bits per pixel, size, transparency, etc.)  ImageInfo image_info = Sanselan.getImageInfo(imageBytes);    if (image_info.getColorType() == ImageInfo.COLOR_TYPE_GRAYSCALE)  System.out.println("Grayscale image.");  if (image_info.getHeight() > 1000)  System.out.println("Large image.");    // try to guess the image's format.  ImageFormat image_format = Sanselan.guessFormat(imageBytes);  image_format.equals(ImageFormat.IMAGE_FORMAT_PNG);    // get all metadata stored in EXIF format (ie. from JPEG or TIFF).  // org.w3c.dom.Node node = Sanselan.getMetadataObsolete(imageBytes);  IImageMetadata metdata = Sanselan.getMetadata(imageBytes);    // print a dump of information about an image to stdout.  Sanselan.dumpImageFile(imageBytes);    // get a summary of format errors.  FormatCompliance format_compliance = Sanselan  .getFormatCompliance(imageBytes);
