C# :: Compare The Image Of A Button To Another Image In Visual Studio
Jul 3, 2014Im trying to compare the image of a button to another image in Visual Studio like so...
//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)

C :: How To Work With 2D Arrays And Image File
Jun 3, 2013This is the first time I'm working with 2d arrays and I have to read the pixels in the input file, then store the pixel from the input image file into the array. And there is a maximum width and height of 500. If the file's too big, then I have to print an error message. Also, my array should only be filled up to the dimensions of the input image file.
I have the code for everything up to that point but I'm not too sure how to approach this. I've defined max_width and height at the top of my file as 500 and I'm thinking of putting this part of the program into a new helper function. But I'm not completely sure how to start, I do know that the array would look something like this though:
int array[max_height][max_width].
1) the syntax of printing the error message/storing the values and 2) the values for my pixels in the input file are all in a single column; each value after the ppm format header is on a new line.
what the input file looks like:
Code:
P3
493 401
255
71
0
0
76
4
5
87
11
NOTE: First three lines are the header information for the ppm format; the numbers that follow go like this: red, green, blue, red, green, blue, etc.
C++ :: Manipulate Image File At Runtime
Oct 20, 2013I've come to a point where I want to manipulate an image file at run time or with pre-determine sizes and have to be applied when the windows is moved or through in program options.
I know I can do the applying part. However I am a little unsure of how to tackle the image manipulation. I want to make it so that it is not os dependant. So I know I can not rely on any os functions. The only other thought that came to mind was to deal with the video card itself.
So the main question after all of that is said and done. How is c++ able to interact with the video card directly for images? Or if there are existing function I can use. How do they do that? If I can use existing function I would like to be able to manipulate it myself.
C/C++ :: Reading And Writing PPM File Image

C/C++ :: Create Image And Output It As PPM File
Jan 26, 2015I have an assignment where I have to create an image and output it as a .ppm file. It has to have a black background and have some letters in a different color. My professor told me that my .ppm header should have p3 600 300 255 and P6 600 300 255(what this means, think it sets up the width x height which should be 300 x 600).
This is what I have so far:
#include <iostream>
#include <fstream>
using namespace std;
int main() {
struct pixel {
unsigned char red;
[Code] ....
Problem in first for loop and what it should look like inside of the for loop, after that I should be able to figure this out... with the fstream (how to output the results in a .ppm file).

C/C++ :: Convert 256 Color BMP Image To TXT File Of Array Of 0 - 255

Visual C++ :: Unable To Read LCT File To BMP Image

Find the attachment. change the file extension *.lct instead of *.txt. I like to read ASCII Data into Hex, Example : Data "A" as "41" (Refer the jpeg image). How is possible?
C++ :: Scanning A Header File To Save Image Data
Jun 11, 2013I'm trying to read from a header file to take the image dimensions and other variables but I don't understand how to iterate through the "key" so it saves each line.
This is what the header file will always look like:
!INTERFILE :=
!imaging modality := nucmed
!version of keys := 3.3
;
!GENERAL DATA :=
[Code].....
Ideally it would just skip the keys that aren't wanted and keep moving through the lines. Should there be a for loop for the key (and if so, how does that work with pointers?) or should this method just be scratched...
C++ :: Convert File (Audio / Image / Video) To Base64?
Sep 7, 2014I'm looking to convert audio, images, video to base64 in c++, and through many searches on the web I've only seem to come up with string > base64.
When I view a .mp3 file for example, there are many characters there that are not available to be used in my string to encode.
[URL] ....
I have this code set up in my project, and all I want is to be able to give the location of any file and have it encode (could just encode to a string, I can handle writing it to a file), and then give a location to put the decoded file as well.
I'm not sure exactly where to even start.
C Sharp :: How To Access Raw Image Data In Resource File
Nov 14, 2012I have a .png file that my console app reads and puts into a structure that is saved as a file. The png is always the same so I thought I could just add it as a resource image to a resource file so it would be included in my program and not as a separate file. When I did that, the png shows up as a "SystemDrawingBitmap". If I examine this resource in a watch I see "Base" and "Static" members. Expanding those properties does not give me anything useful such as a pointer to the raw png data and its length in bytes.
If worse comes to worse, I can always make a hex dump of the png contents and then put the hex code into a CS file using static initialization.
Surely there is some way I can access the raw data internally and read the bytes into a byte array using C#
C++ :: Image / Video Compression Project - Error In Reading File
Apr 3, 2012I have this image/video compression project that is to be done in C. I've been given this source code by my supervisor which is supposed to be a working one.
Assuming I have a sequence of 5 images in .pgm format (image41.pgm, image42.pgm .... image45.pgm). Some of the code involved is
Code:
#define START_FRAME 41
#define END_FRAME 45
#define SKIP_FRAME 1
#define INPUT_STRING "/home/folder/image%03d"
int main(){
int frameNo = START_FRAME
nx=1920, ny=1080;
char fileName[128];
[Code] ....
When I tried to compile the code using make file (shell script), I got this error message "In function 'readPgm' format '%d' expects argument of type 'int *', but argument 3 has type 'unsigned char *' "
Can identify what the problem is and how to rectify it?

C :: Editing Image In PPM Format
Mar 10, 2014I'm trying to edit an image by multiplying the red component of each pixel by 10 and leaving the other components (green and blue) untouched. I'm not really sure how I'm supposed to edit the pixels one by one. I have this so far. I think there is something wrong with my ppm header as well. Is there a way to make a ppm header without specifying the bounds so that it conforms to the image you are putting in?

#include <stdlib.h>
#include <stdio.h>

#define MIN_ARGS 2

C :: Read A 24 Bit Image Using 2D Array
Oct 29, 2013I am trying to read a 24 bit image but I'm getting errors when I'm tryting to read the pixels.
-The reading part looks bad because I'm reading both headers field by field. But I'm sure that it is reading both headers correctly.
-Right now my biggest concern is to get it to read successfully an entire bmp image
I'm using this calculation to get my padding bytes:
padding bytes = [4-(3*width)mod 4]mod 4
When I use a 2x2.bmp file to test it, I get an error that the [1][1] pixel was not read. When I use a bigger image it gives me the same error after about 100 rows and then every pixel is an error from that point on. This is what I got so far:
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
const size_t cSizeofPixel = 3; //size of struct tPixel
typedef struct{
unsigned char blue;
unsigned char green;
unsigned char red;
[Code]...
I read this post Reading 24 bit BMP file into a 2d array.
I still don't know if my error is when I allocate memory to my 2d array, or if I'm doing the padding bytes wrong or if it is something else.
