L_INT EXT_FUNCTION L_PicturizeBitmapSingle(pBitmap, pThumbBitmap, uCellWidth, uCellHeight, uLightnessFact)
|
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
|
pBITMAPHANDLE pThumbBitmap; |
/* pointer to the thumbnail bitmap handle */ |
|
L_UINT uCellWidth; |
/* thumbnail width */ |
|
L_UINT uCellHeight; |
/* thumbnail height */ |

L_UINT uLightnessFact; |
/* lightening or darkening value */ |
Picturizes the specified bitmap using the specified thumbnail image.
|
Parameter |
Description |
|
pBitmap |
Pointer to the bitmap handle that references the bitmap to be picturized. |
|
pThumbBitmap |
Pointer to the bitmap handle that references the bitmap used to create the thumbnail. |
|
uCellWidth |
Width of the thumbnail bitmap. |
|
uCellHeight |
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. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The image, or selected region, is broken down into rectangles of size uCellWidth x uCellHeight. For each rectangle, the thumbnail image is corrected to approximate that rectangle, and inserted in the original image. Note that every rectangle is replaced by the same image.
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. Supportfor 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.

Example
/* This example loads a bitmap and picturize it with the same bitmap. */
BITMAPHANDLE LeadBitmap; /* Bitmap handle to hold the loaded image. */
/* Load the bitmap, keeping the bits per pixel of the file */
L_LoadBitmap (TEXT("IMAGE1.CMP"), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
/*Picturize the bitmap */
L_PicturizeBitmapSingle(&LeadBitmap, &LeadBitmap,20,15,200);
