virtual L_INT LBitmapBase::Resize(pLBitmapDst, uStructSize, uFlags)
Resizes the class object's bitmap and places the resized bitmap in the destination class object.
Pointer to a LBitmapBase bitmap object that will be updated with the resized bitmap.
Size of the BITMAPHANDLE structure used by the object. Pass sizeof(BITMAPHANDLE).
Flags that control the behavior when resizing the bitmap. Use one of the following:
|SIZE_NORMAL||[0x0000] Resize normally.|
|SIZE_FAVORBLACK||[0x0001] (Document/Medical only) Preserve black objects when making the image smaller. This option affects only 1-bit, black-and-white images, where it prevents the disappearance of thin lines. You can use a bitwise OR ( | ) to combine this flag with another one. For example, SIZE_RESAMPLE | SIZE_FAVORBLACK causes color images to be resampled, but applies the favor-black option to 1-bit, black-and-white images.|
|SIZE_RESAMPLE||[0x0002] Use linear interpolation and averaging to produce a higher-quality image.|
|SIZE_BICUBIC||[0x0004] Use bicubic interpolation and averaging to produce a higher quality image. This is slower than SIZE_RESAMPLE.|
|SIZE_SCALETOGRAY||[0x0008] (Document/Medical only). Use interpolation to display black and white images using shades of gray when the image is resized. This improves the readability when the image is scaled up or down. The generated image is 8-bit grayscale, so this option should be used only for black and white images.|
|SIZE_OLD_RESAMPLE||[0x0010] Use the old resample algorithm from LEADTOOLS 14.5.|
|SIZE_PREMULTIPLYALPHA||[0x0020] Premultiply the alpha channel values when performing resize.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function will use the width and height specified in the destination class object for the resize operation.
LBitmapBase MyBitmap, ResizeBitmap;
nRet =ResizeBitmap.Create(100,100,24,ORDER_BGR, NULL,TOP_LEFT,TYPE_CONV);
nRet = MyBitmap.Resize(&ResizeBitmap, sizeof(BITMAPHANDLE), SIZE_NORMAL); //this will resize MyBitmap and put the resized image in ResizeBitmap
