displays Hi c 10 there! If there are insufficient arguments to match the format commands, the output is undefined If there are more arguments than format commands, the remaining arguments are discarded The printf( ) function returns the number of characters actually printed A negative return value indicates an error The format commands may have modifiers that specify the field width, the precision, and left-justification An integer placed between the percent sign and the format command acts as a minimum field-width specifier, padding the output with blanks or zeros to ensure that it is a minimum length If the string or number is greater than that minimum, it will be printed in full The default padding is done with spaces For numeric values, if you wish to pad with zeros, place a zero before the field width specifier For example, %05d pads a number of less than five digits with zeros so that its total length is five digits

The effect of the precision modifier depends upon the type of format command being modified To add a precision modifier, place a decimal point followed by the precision after the field-width specifier For e, E, and f formats, the precision modifier determines the number of decimal places printed For example, %104f displays a number at least ten characters wide with four decimal places However, when used with the g or G specifier, the precision determines the maximum number of significant digits displayed When the precision modifier is applied to integers, it specifies the minimum number of digits that will be displayed (Leading zeros are added, if necessary) When the precision modifier is applied to strings, the number following the period specifies the maximum field length For example, %57s displays a string that is at least

Associated argument is a pointer to an integer into which is placed the number of characters written so far

Mar 7, 2016 · In this article I am going to show how to do OCR using Tesseract in C#.

We ve added a check to see if a parameter has been passed and if the parameter is the string value inverse b. If it is, then we invert the color c before returning it. Pretty easy. Now, when we run, we can always read the text (figure 12.29), although sometimes the colors are a little ugly.

_dos_write( )

14:

Transmit power distributed across hundreds of modes (high modal-dispersion)

Figure 12.29 Using the parameter of the MultiValueConverter, we have the color of our label changing inversely to the color of the background. Better (or at least more diligent) coders might have come up with an algorithm that avoided uglier text colors.

unsigned _dos_setdate(struct dosdate_t *d) unsigned _dos_settime(struct dostime_t *t)

The prototypes for _dos_setdate( ) and _dos_settime( ) are in <dosh> These functions are not defined by the ANSI/ISO C/C++ standard These functions are obsolete and not recommended for future code The _dos_setdate( ) function sets the DOS system date as specified in the structure pointed to by d The _dos_settime( ) function sets the DOS system time as specified in the structure pointed to by t The dosdate_t structure is defined like this:

struct dosdate_t { unsigned char day; unsigned char month; unsigned int year; unsigned char dayofweek; };

We re passing a pretty simple parameter to get our result, but the parameter could be any value and could be used in any way by the converter. One flaw with our display is that it s showing an ugly hex value for our color, whereas, for some colors at least, they have real names. (In our book, of course, the names will always be black, white, or gray still not bitter about the color thing, though.) One way of cleaning this up is by using a StringFormat with our MultiBinding.

Fiber loss (dB/km)

/* Sunday is 0 */

The dostime_t structure is defined as shown here:

It isn t always necessary to build a converter to combine values in some way. You saw earlier how it s possible to format a single bound value using StringFormat;we can do the same thing with a MultiBinding (listing 12.16).
