Image Options
Barcode Xpress works with 1-bit black and white images, 8-bit grayscale images, and 24-bit color images. To convert other image formats use the ImagXpress ColorDepth method or other methods with the included ImagXpress component. If you use ImageGear, use the ConvertColorSpace method.
| C++ Example - Minimum C++ code to load an image using Accusoft.ImagXpress11.ActiveX |
 Copy Code |
//load a 1BPP, black and white image into the ImagXpress control
m_pImagXpress->FileName = “C:\\testbarcodeimage.tif”;
// Copy the hDib
long hDib = m_pImagXpress->CopyDIB();
// Analyze the barcode
m_pBarcodeXpress->AnalyzehDib(hDib);
// Free the hDib
GlobalFree(LongToHandle(hDib));
|
| VB Example - Minimum VB6 code to load an image using Accusoft.ImagXpress11.ActiveX |
Copy Code |
' Load the image
ImagXpress1.FileName = "C:\testbarcodeimage.tif"
' Copy the hDib
hDib = ImagXpress1.CopyDIB
' Analyze the barcode
BarcodeXpress1.AnalyzehDib hDib
' Free the hDib
GlobalFree hDib

| C++ Example - Minimum C++ code to load an image using ImageGear |
Copy Code |
// Create an ImageGear page
GearCORELib::IIGPagePtr page;
page = g_pIGCore->CreatePage();
// Load the page from file
m_pIGFormats->LoadPageFromFile(page, fileName, 0);
// Export the page to a dib
GearCORELib::IIGPlatformDIBPtr platformDib = page->PlatformDIBExport(GearCORELib::IG_DIB_EXPORT_FORMAT_WINDOWS, false, 0, 0, page->ImageWidth, page->ImageHeight, 0);
HGLOBAL hDib = LongToHandle(platformDib->DIBPtrGet());
// Read the barcodes
pBarcodeXpress->AnalyzehDib(HandleToLong(hDib));
|
| VB Example - Minimum VB6 code to load an image using ImageGear |
Copy Code |
' Load the Page
Dim page As New IGPage
IGFormatsCtl1.LoadPageFromFile page, fileName, 0
' Export the platform dib from the page
Dim platformDib As IGPlatformDIB
Set platformDib = page.PlatformDIBExport(IG_DIB_EXPORT_FORMAT_WINDOWS, False, 0, 0, page.ImageWidth, page.ImageHeight, 0)
' Get the dib handle
Dim hDib As Long
hDib = platformDib.DIBPtrGet
' Read the barcodes on the image
bcx8.AnalyzehDib hDib
