L_UINT uyDim;

L_UINT uLightnessFact;

L_UINT32 uFlags;

flags

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

Parameter

Description

uxDim

Width of the thumbnail bitmap.

uyDim

Height of the thumbnail bitmap.

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.

pBitmapList

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

uFlags

Reserved for future use. Must be 0.

Returns

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.
