; HBBMP is small library for Harbour dedicated to create and modify
BMP images. It has not any 3rd party libs dependencies.
See readme.txt for more information

+ contrib/hbzebra/tests/bmp.prg
+ added example code which uses HBBMP as backend for HBZEBRA and
creates BMP images with generated barcodes.

Hi Przemek,

Thanks for the new toy hbbmp.

# Two tiny but important fixes / adds

1. Wrapper typo (y argument): In the C wrappers for HB_BMP_PUTPIXEL and HB_BMP_GETPIXEL, the y parameter is parsed as hb_parni( hb_parni( 3 ) ) instead of hb_parni( 3 ). Replace both occurrences (shown below) or you’ll pass garbage for Y:

diff
- hb_retl( hb_bmp_putpixel( pBMP, hb_parni( 2 ), hb_parni( hb_parni( 3 ) ), hb_parnint( 4 ) ) );
+ hb_retl( hb_bmp_putpixel( pBMP, hb_parni( 2 ), hb_parni( 3 ), hb_parnint( 4 ) ) );

- hb_retnint( hb_bmp_getpixel( pBMP, hb_parni( 2 ), hb_parni( hb_parni( 3 ) ) ) );
+ hb_retnint( hb_bmp_getpixel( pBMP, hb_parni( 2 ), hb_parni( 3 ) ) );

Hope this is helpful.

Best regards,

Grigory

Hi Przemek,

Can you add hbbmp to contrib/hbplist.txt, please ?

Thank you.

Hi, for VS C++, build could be fixed using:

diff --git a/src/rtl/filebuf.c b/src/rtl/filebuf.c

Is it not better to use this way?

HB_BOOL hb_fileSave( const char * pszFileName, const HB_BYTE * buffer, HB_SIZE nSize )
