Hi There, Please refer to your following page: FreeType Tutorial / I<https://freetype.org/freetype2/docs/tutorial/step1.html>
Please confirm/explain if the part that I’ve highlighted in Red below, is in error? I mean... please kindly explain what it’s trying to say? “expressed in 1/64th of a pixel”, but then specifically... for “a character size of 12 points”? What about point sizes other than 12? (Sorry if I’m missing something, but that has me quite confused 😊) Thank you in advance, cheers, Gary. FreeType 2 uses size objects to model all information related to a given character size for a given face. For example, a size object holds the value of certain metrics like the ascender or text height, expressed in 1/64th of a pixel, for a character size of 12 points (however, those values are rounded to integers, i.e., multiples of 64). When the FT_New_Face function is called (or one of its siblings), it automatically creates a new size object for the returned face. This size object is directly accessible as face−>size. NOTE: A single face object can deal with one or more size objects at a time; however, this is something that few programmers really need to do. We have thus decided to make this feature available through additional functions. When a new face object is created, all elements are set to 0 during initialization. To populate the structure with sensible values, you should call FT_Set_Char_Size<https://freetype.org/freetype2/docs/reference/ft2-base_interface.html#ft_set_char_size>. Here is an example, setting the character size to 16pt for a 300×300dpi device: error = FT_Set_Char_Size( face, /* handle to face object */ 0, /* char_width in 1/64th of points */ 16*64, /* char_height in 1/64th of points */ 300, /* horizontal device resolution */ 300 ); /* vertical device resolution */ Some notes. * The character widths and heights are specified in 1/64th of points. A point is a physical distance, equaling 1/72th of an inch. Normally, it is not equivalent to a pixel. * Value of 0 for the character width means ‘same as character height’, value of 0 for the character height means ‘same as character width’. Otherwise, it is possible to specify different character widths and heights. * The horizontal and vertical device resolutions are expressed in dots-per-inch, or dpi. Standard values are 72 or 96 dpi for display devices like the screen. The resolution is used to compute the character pixel size from the character point size. * Value of 0 for the horizontal resolution means ‘same as vertical resolution’, value of 0 for the vertical resolution means ‘same as horizontal resolution’. If both values are zero, 72 dpi is used for both dimensions. * The first argument is a handle to a face object, not a size object.
