Hi,
I try to extract the bitmap of a character (single). Every time I
specify the same Height for the character entered but the bitmap
contains different height for different
Character. I need them to be same since I use the bitmap as lookup
table in my program. Can anybody suggest the way to do it. I'm very new
to freetype (using freetype2). Help required Urgently.
Code I use is,
/* Initialize the free type library */
error = FT_Set_Char_Size (face, /* Handle to face
object */
width * 64, /* char_width in 1/64th of points */
height * 64, /* char_height in 1/64th of points */
72, /* horizontal device resolution */
72); /* vertical device resolution */
//FT_Set_Pixel_Sizes (face,width,height);
/* Get the Glyph Index */
/* Index is used to load the glyph image from the glyph
table */
index = FT_Get_Char_Index(face, /* Handle to the face
object */
char_code); /* Character code , Using Single Character*/
/* Loading the glyph image to the slot */
error = FT_Load_Glyph (face, /* Handle to the
face object */
index, /* index to glyph table */
FT_LOAD_DEFAULT); /* load flag */
if ( error )
return FONT_FAILURE;
slot = face->glyph;
/* Convert glyph image to bitmap */
error = FT_Render_Glyph(slot, /* glyph slot
*/
FT_RENDER_MODE_NORMAL); /* Rendering mode */
if ( error )
return FONT_FAILURE;
/* output variables */
*bmp_width = face->glyph->bitmap.width;
*bmp_hght = face->glyph->bitmap.rows;
buf_size = (*bmp_width) * (*bmp_hght);
/*"I need the Bitmap's Height to be constant for all
characters" */
memcpy (bitmap,face->glyph->bitmap.buffer,buf_size);
FT_Done_Face ( face );
FT_Done_FreeType( library );
Thanks,
Sharath
