I want to use a new color for BaseColor in iTextSharp.
I can easily set a new color using RGB values from 0 to 255.
However, if I want to adjust the alpha value (and I know alpha ranges from 0 to 1), I can't make the alpha 0.5 because it's not an integer in the definition of BaseColor.
public BaseColor(int red, int green, int blue, int alpha);
So I can set my BaseColor like below:
static BaseColor newColor = new BaseColor(192, 192, 192);
but I can't use a non-int value for alpha. How can I easily convert double alpha values to integer values? What would be the range for alpha in int values and how do I, e.g., set the alpha value to 0.5 in int values?
EDIT: btw, I found online something like this: int alpha = (pixel >> 24). I don't understand why 24 and how can I break that into chunks I understand?
I found a targa loader that works great and implemented it in my code.
But for some reason, the alpha region of my texture , just won't be alpha when I load the Texture in my code.
If I make a texture that is a full purple colored rectangle, and carve out the central part with an alpha zone, in-game the quad is all full purple, instead of having the central part being transparent.
I tried the following code too, and it doesn't work, I don't understand
//NPC glEnable(GL_BLEND);// Enable Blending NPC00->Draw(); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);// Set The Blending To A Nice 50/50 Mode glDisable(GL_BLEND);// Disable Blending
Draw Function, basically draws a Quad and applies the texture to it.
I'm just trying to get textures with alpha to work, I usually work with targas, so thats why I got a targa loader.
I am currently using Dev-C++ 4.9.9.2 compiler for creating a C project. I need few strings to be printed in a different color.
Code: #include<stdio.h> #include<conio.h> int main(void) { textcolor(RED); cprintf("Hello world "); system("pause"); }
While I use " textcolor(RED) " it says: 'RED' undeclared, first use in this function.
If i make it: " textcolor(3) ", it says: [Linker error] undefined reference to textcolor & undefined reference to cprintf.
have been searching for a solution on google since morning. At last I could make out that it is not the correct compiler with suitable library or outdated <conio.h> header file.
I had switched from turbo(or borland, I don't remember) to Dev-C++ compiler due to some kind of library issue. Now I guess I'll have to switch to some other IDE. Which one is that, I don't know yet. There was another thread also about this topic, but didn't provide any solution.
Is there any method to upgrade certain header file (I don't think so)? What would be the best IDE with updated libraries?
I want to write a function called DrawLineSegments.This function must change the color of lines at every corner where the corner angle is greater than 60 deg (Assume that there is a function called checkangle). The color sequence must be black, red, green, blue, and repeat this sequence after the fourth color.
void generate_all_color_pairs(){ int foreground; int background; int i = 0; for(foreground=0; foreground<8; foreground++){ for(background=0; background<8; background++){ i++;
[code]....
but according on several sources, some terminals suport more colors.Is there any way to determine how many colors the current terminal supports?
I'm trying to make colors transparent in c++ using a 3rd party library. I've successful made my background transparent but I feel I'm cheating by not understanding how I entered the value.
"0xff, 0xff, 0xff" is the color white but i'm not sure how it's the color white like with RGB values.
Basically I am making a console RPG (isn't every beginner nowadays?) and I am having an incredible amount of trouble assigning specific characters their own color. e.g. monsters being red, cash being green, etc.
I took out Left, Right, and Down controls because of character constraint.
#include <iostream> #include <windows.h> //%%%%%%%%%%%%%% COLOR CALL %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% void setcolor(unsigned short color) { HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE); SetConsoleTextAttribute(hcon,color);
Why the first code snippet inserts properly into a list and the second code snippet does not. The position of the bold expressions are the only differences. iter, s and LS were declared elsewhere in main().
snippet 1.) while (true) { cout << "Enter string (ENTER to exit): "; getline(cin, s); if (s.size() == 0)
I am currently starting to attempt to make a program that can move my cursor to certain colors on my monitor. The problem is this seems like it will be 10x harder than I first thought.
Suppose I have a txt file that I want the contents printed to the console in such a way that every five words are colored blue and the following five are red. How do I accomplish such a task? I am currently only able to print the contents of the file in regular color using ifstream.
I have a template mock up view using xaml. I have a viewmodel that raises the message property. I binded the message property to a textblock inside my xaml.
Since my messages are different for every viewmodel I have.
E.g.in every viewmodel, I have something like
messagewindow.Message = "This is a new message"; dialogService.ShowDialog(Success, messageWindow);
In one of my messages, I want to make the font bold and different color for a specific message segment.
How can I do that without messing up with the other messages that inherit from the xaml or code behind?
Currently, I'm not using any code behind and a lot of the examples online I've seen use code behind and/or don't have dynamic message textboxes.
I want to create 2 functions to (1) convert a passed string into proper case (capitalize the first alpha character of a string and every alpha character that follows a non-alpha character); (2) sort the array of names (after it has been converted to proper case).
I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
changing a 9 digit integer into a new 9 digit integer through simple mathematical operations. For example, I need to change 123456789 into the new digit 456123789. Sometimes I need to change a 9 digit integer into an 8 digit integer. An example is 789062456 into 62789456. I can ONLY use simple mathematical operations (addition, subtraction, multiplication, division and modulo).
I have an assignment that calls for a C program using a for loop AND a while loop that will receive an integer (called daNumba) and double it -- Using the integer the program will call the sumFor function and then the sumWhile function. These functions will both sum the values from daNumba to (daNumba * 2) ifdaNumba is positive. If daNumba is not positive it will add the values from (daNumba*2) to daNumba. Both functions will receive the value of daNumba and return a summed value. The only difference between the 2 functions is that sumFor will only use for loops and sumWhile will only use while loops. We are not to use arrays.
The program compiles without error. So far my while loop works for positive integers, but not with a negative integer (I have it commented out) I cannot get the for loop to work properly This is what I have so far -- I am stuck....
Code: #include<stdio.h> #include<stdlib.h> #include<math.h> int main () {
i have the following problem to solve.... im unable even to start with an idea....can anybody help me giving an idea how to do this problem?
the problem is: ___*****____ Write a C++ program that factorize an integer n into p and q. Step1. reads an integer n from the keyboard. Step2. Write a for loop as below to check if there is any factor j > 1.
for (int j = 2; j <= square root of n; j ++) { If (n % j == 0) { factorizable = true; break; } }
Step3. If there is no such factor, print the message n is not factorizable. If there is such a factor j, check programmatically if j is a prime and n / j is a prime Also check if j and n / j are the same.
