LEADTOOLS provides several functions for getting information on various aspects of bitmaps. The following functions provide information on bitmap characteristics such as dimension, color order, size, resolution, etc.

LBitmapBase::GetBitsPerPixel

LBitmapBase::GetBytesPerLine

LBitmapBase::GetColorCount

LBitmapBase::GetColorOrder

LBitmapBase::GetHeight

LBitmapBase::GetMemSize

LBitmapBase::GetWidth

LBitmapBase::GetXResolution

LBitmapBase::GetYResolution

Information about the memory associated with a bitmap can be obtained using the following functions:

LBitmapBase::GetMemSize

LBitmapBase::Is1BitCompressed

LBitmapBase::IsAllocated

LBitmapBase::IsMemoryLocked

LBitmapBase::IsUsingConventionalMemory

LBitmapBase::IsUsingDiskMemory

To get information about display characteristics of a bitmap, use the following functions:

LBitmapBase::GetDefaultDithering

LBitmapBase::GetDitheringMethod

LBitmapBase::GetPaintContrast

LBitmapBase::GetPaintGamma
