Gnostice Document Studio Java is the next-generation
multi-format document-processing component suite for J2SE/J2EE developers.
Currently, it supports viewing, printing, and converting PDF, DOCX,
BMP, JPEG, PNG, JPEG2000 and single-page/multi-page TIFF.
Document Studio can process PDF and DOCX without
requiring external software such as Microsoft Word, Open XML SDK, Adobe PDF
library or GhostScript. (For supporting advanced image formats such as JPEG2000
or TIFF, the library Java Advanced Imaging is required. For processing simple
image formats such as BMP, PNG or JPEG, the Java Advanced Imaging library is not
required.) When converting to PDF (on Windows), Document Studio can perform OCR
text recognition on raster images and create corresponding searchable/selectable
PDF text elements.

Choosing Your License:
For Development: Get one DEVELOPER SUBSCRIPTION for each
developer. With one DEVELOPER SUBSCRIPTION, a developer can
install the GNOSTICE PRODUCT in one desktop and one laptop
that the developer uses. For installing on additional
computers, buy additional DEVELOPER SUBSCRIPTIONS.
Developer licenses are available at discounted prices for purchase
quantities greater than 4. Larger teams are recommended to buy the 5-Developer,
10-Developer and 25-Developer Subscription Licenses.
For Distribution:
To develop/test/deploy/distribute most kinds of software applications using

developer or additional computer. No additional royalty would be required.
If the software that you are creating is a developer tool and
exposes functionality provided by the GNOSTICE PRODUCT using an
application programming interface (API) (say a component library or
a Web API), then get an SDK LICENSE in addition to your DEVELOPER
SUBSCRIPTION(s). You need to mail us describing your product.
If the software that you are creating is a developer tool
(say an IDE) AND bundles the GNOSTICE PRODUCT in a non-compiled

If you are a student and want to use the GNOSTICE PRODUCT
for your project work, then you can get the low-priced STUDENT
ACADEMIC LICENSE instead of the more expensive DEVELOPER
SUBSCRIPTION. You need to mail us describing your project.
