About

Although PDF (Portable Document Format) is widely used in the world, its potential ability is not appreciated enough. A various application is achieved if the PDF is generated directly from computer program. One of the remarkable functions is a color management. You can view an OS independent color tone in Acrobat Reader if the image and ICC profile are embedded together in PDF. Recursion's Direct PDF is a high-speed, light-weight PDF generating technology without Adobe's license. You can apply it for image management, internet distribution, or building printing workflow, under various OS platforms. These are some sample utilities.

  1. Jpg2pdf:     Convert JPEG to PDF using ICC profile
  2. Sepia:     Make Masked Sepia image
  3. Dozen:     Tile Dozen images
  4. Index:     Generate Image Index
  5. Combine:     Combine JPEG images into single file
  6. Circle:     Make Circular Chart
  7. AN5:        PDF Cipher

All the binaries above are included. These are freeware.

Platform:    Windows 2000/XP                 pdfunny15.zip (350KB)
                MacOS 9.2, 10.1.5�`            pdfunny14.sit (110KB)

Set screen mode to "True Color(24bit)" or "High Color(16bit)" to view Color-managed image on Acrobat Reader. Input file must have an extension (e.g. ".jpg", ".icc").


Jpg2pdf (JPEG to PDF Converter)

You can embed a JPEG image into PDF file without changing it. Wrapping the image with a little PDF form makes it readable by PDF viewer.
This utility makes use of the color management. It embeds an image and the ICC profile together into PDF form, with the priority below.

(1) Use profile if embedded in JPEG header.
(2) Use profile if dropped into this application with image.
(3) Use default profile if the image color is sRGB or sGray(gamma 2.2).

You can see the name of embedded profile at subject field of [Document Properties].

(Source)         JPEG-Gray, JPEG-RGB,
                    JPEG-CMYK (Use external/embedded profile for JPEG-CMYK )
(Operation)     Drop image file(s) and ICC profile (option) into application icon.
                    Then "image_file_name.pdf" will be generated.


Sepia (Sepia Color Converter)

This utility makes use of the soft masking. It binds image and mask with transparent manner. Modify the mask pattern (data\mask.jpg) at your own. Sepia color profile is embedded with image.

(Source)         JPEG-RGB only
(Operation)     Drop image file(s) into application icon.
                    Then "image_file_name.pdf" will be generated.


Dozen (Dozen Faces Generator)

This sample refers to the same image multiple times. Produce your photograph as much as you want.

(Source)         JPEG-Gray and JPEG-RGB
(Operation)     Drop image file(s) into application icon.
                    Then "image_file_name.pdf" will be generated.


Index (Image Index Generator)

This makes an index of images in folder. The generated PDF is small since it refers to images externally. Using external streams is disabled by default - with a preference on the Trust Manager panel to enable it.

(Source)         JPEG-RGB only
(Operation)     Drop image folder into application icon. Then "index.pdf" will be generated in the folder.


Combine (Image Combined PDF Generator)

This combines images in folder to a single PDF file. It makes easier to view or exchange images. You can extract images by dropping the PDF to application icon again (File creation date will be lost).

(Source)         JPEG-RGB only
(Operation)     Drop image folder into application icon.
                    Then "folder_name.pdf" will be generated in the folder.
(Extract)        Drop the generated PDF file into application icon.
                    Then the original folder (and images) appears.


Circle (Circular Chart)

This makes a circle graph. Print and Mail it to your friend.

(Source)         Tab, comma separated list of "title", "item", and "percentage" (Text file).
(Operation)     Drop text file (e.g. sample.txt)  into application icon.
                    Then "file_name.pdf" will be generated.


An5 (PDF Cipher)

This converts any files to cipher image. You can decode it by dropping the PDF to application icon again, but may not be needed for text  file (?). It uses the world quickest cipher algorithm - PBP. Use it freely for your very important confidential document.

(Source)         Any file except PDF.
(Operation)     Drop image file(s) into application icon.
                    Then "file_name.pdf" will be generated.
(Extract)        Drop the generated PDF file on application icon.
                    Then the original file appears.
                    You can extract image from Jpg2pdf, Sepia, Dozen PDFs too.
