scala-thumbnailer

A Scala library for generating thumbnails.

The API uses streams rather than files. Supports the following file types:

• PDF
• PNG, JPEG, GIF, BMP
• DOCX
• Plain text files

GPL v2.0

This fork exists to update the following versions:

• Scala - v2.11 family
• Apache PDFBox library dependency to the 2.x family
• Typesafe Scala Logging to the 3.5.x family

No other code has changed.

Usage

Create

val defaultThumbnailer = new Thumbnailer
val thumbnailer = new Thumbnailer(new PDFThumbnailer, new TextThumbnailer)

Output to stream

val thumbnailer = new Thumbnailer
val input = new FileInputStream("input.pdf")
val output = new FileOutputStream("output.png", false)

thumbnailer.generateThumbnail(input, output, "application/pdf")

output.close
input.close

Output to byte array

val thumbnailer = new Thumbnailer
val input = new FileInputStream("input.pdf")

val bytes: Array[Byte] = thumbnailer.generateThumbnail(input, "application/pdf")

input.close

Options

val thumbnailer = new Thumbnailer
thumbnailer.setSize(100, 200)
