Dear Friends,

I am using LeadTools 13 Pro with Visual Studio 8 (with API). I need to load an image file and obtain the pointer to the pixels. How can I do? Is there somebody who can help me?

Thanks in advanced.

Martín Pastor.

Martín,

There are two ways to do this:
(1) You can create the Bitmap using the L_CreateBitmap and pass TYPE_USER to the uMemory parameter. Then pass your own pointer to the pData parameter. For more information, please read the following help topics in the LEADTOOLS API help file:
- L_CreateBitmap
- L_SetBitmapDataPointer

(2) After loading the image, use the L_GetBitmapRow function to copy the image data from the bitmap to a buffer that you specify.
For more information, please read the following help topic in the LEADTOOLS API help file:
- L_GetBitmapRow

Thanks,
