text

Dear sir,

In the C program, how can I,

(a) make the text blinking

(b) manipulate the size of the text

(c) manipulate the background color


Thanks

You'd have to use graphics library.

the first and third you can do with out graphics libraries. the second you do

text way:

1) set up 3 for( ; ; ) statements that contain the rgb values that you will use. increment or set the value each one to a different number and when it gets to a certain value set back to the original 1:


for (r = 0; r < 255; r = 255)
{
if (r = 255)
{
r = 0;
}
}

for (g = 0; g < 255; g = 255)
{
if (g = 255)
{
g = 0;
}
}

for (b = 0; b < 255; b = 255)
{
if (b = 255)
{
b = 0;
}
}


after this you draw the text to the screen and it will flash black and white.

for #3 it would be something like this:


switch(r)
case 0:
r2 = 255;
case 255:
r2 = 0;

switch(g)
case 0:
g2 = 255;
case 255:
g2 = 0;

switch(b)
case 0:
b2 = 255;
case 255:
b2 = 0;


then you draw a primitve rectangle around the text at a point fixed to a certain distance from the text.

the second question of yours i believe must have some special graphics library to do stretching of a animated blinking image with text. if you use C or C++ check out allegro at Allegro (http://www.allegro.cc/). this has a "stretch_blit()" function.
