LBitmap::PicturizeList

#include "ltwrappr.h"

virtual L_INT LBitmap::PicturizeList(uxDim, uyDim, uLightnessFact, pBitmapList, uFlags = 0)

Picturizes the class object's bitmap using thumbnail images created from the specified bitmap list.

Parameters

L_UINT uxDim

Width of the thumbnail bitmap.

L_UINT uyDim

Height of the thumbnail bitmap.

L_UINT uLightnessFact

Value that represents how much to lighten the thumbnail bitmap. Valid values are between 0 and 1000. This value is divided internally by 1000. Values between 0 and 499 darken the image. Values between 500 and 1000 lighten the image.

LBitmapList * pBitmapList

Handle to the list of bitmaps used to create the thumbnail images which are in turn used to picturize the specified image.

L_UINT32 uFlags

Reserved for future use. Must be 0.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

The class object's bitmap, or selected region, is broken down into rectangles of size uxDim x uyDim. For each rectangle, the image in the list that best approximates that rectangle is inserted in the original image. The thumbnail image may be corrected, to approximate a rectangle.

The uLightnessFact parameter can be used to change the lightness of the big image by changing the lightness of each rectangle.

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
