Java圖像處理庫 Sanselan

Sanselan 是一個純 Java 的圖形庫，可以讀寫各種格式的圖像文件，包括快速解析圖片信息例如大小/顏色/icc以及元數據等。盡管因為是Java開發的，在處理速度上會稍微慢一 些，但具備良好的可移植性。雖然尚未發布1.0 版本，但是已經有多個項目在使用 Sanselan 來處理圖像文件。

該項目目前還是 Apache 組織的一個孵化項目。

示例代碼：

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);
