Nuance SDK in Go

This is a wrap of OCR libraries provided by Nuance in their SDK.

The goal is to use the OCR SDK features without polluting the code written in Go with many C calls as well provide a more task-based API, therefore this package does not exposes all nuance C API, instead many calls in C will be condensed in a few Go calls.

Examples

SetLicence and initialise

n := nuveo.New()
err := n.SetLicense("licence.lcxz", "OEM_CODE")
if err != nil {
    error.Fatal("SetLicense failed:", err)
}

err = n.Init("YOUR_COMPANY", "YOUR_PRODUCT")
if err != nil {
    error.Fatal("Init failed:", err)
}

n.Quit()
n.Free()

---

Processes zones

Processes image and template and extract information from zones.

n := nuveo.New()

// load the license
err := n.SetLicense("licence.lcxz", "OEM_CODE")
if err != nil {
    fmt.Fatal("SetLicense failed:", err)
}

// initialize the library
err = n.Init("YOUR_COMPANY", "YOUR_PRODUCT")
if err != nil {
    fmt.Fatal("Init failed:", err)
}

// load the template file.
err = n.LoadFormTemplateLibrary("template.ftl")
if err != nil {
    fmt.Fatal("LoadFormTemplateLibrary failed:", err)
}

// loads and processes the image then returns a
// map with the zone marked in the templete.
var ret map[string]string
ret, err = n.OCRImgWithTemplate("sample.tif")
if err != nil {
    fmt.Fatal("OCRImgWithTemplate failed:", err)
}

// echoes the result on the screen
for k, v := range ret {
    fmt.Println("k:", k, "v:", v)
}

// close the library and frees the memory
n.Quit()
n.Free()

Running the tests

At this point of development to run unit tests is necessary to provide your own license files, templates and samples.

Installation

First install the 19.2 version of Nuance SDK

Debian Linux example:

dpkg -i nuance-omnipage-csdk-lib64_19.2-15521.100_amd64.deb
dpkg -i nuance-omnipage-csdk-devel_19.2-15521.100_amd64.deb

Then download the package

go get github.com/nuveo/nuance

To activate your licenses use the following command

oplicmgr -c OEM_CODE -N licence.lcxz PRODUCT_KEY1 PRODUCT_KEY2 PRODUCT_KEY3

You will need your license file and your OEM code in all the examples and tests.
