C++ :: Saving RGB Pixel Data Of JPEG Image In 3D Array
Jan 6, 2015I need to save RGB values of each pixel in a 3D array A[width][height][3]. I found a code online that transfers the bytes into an array but I cant understand how bytes are saved them so i could transfer them into an array. The truth is I dont know much about working with images at all so i have a problem working on them. How to transfer the RGB data from an .jpeg image into a 3D array? This is my code so far:
#include <iostream>
#include <jerror.h>
#include <jpeglib.h>
using namespace std;
int main(){
FILE *pic = fopen( "image.jpeg", "rb+" );

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)

Visual C++ :: MFC DLL To Interact With API - Program Crashes After Displaying 100 Bars?
Apr 27, 2013I have written a MFC dll to interact with an API and it is run by the target program. the first 100 bars are drawn properly but then the program ceases to operate. I am guessing I have a memory leak but I probably just dont understand what I am doing as I am quite new to programming MFC GDI. Here is my code that causes the trouble...
The variables coming in are commented out to facilitate testing and so it would be displaying the same bars over and over because of this. it worrks for 100 bars, then crashes.
void MainDlg::SS_UpdateChart() {
// the chart plot is completely recalculated each time a new bar is shown
// 300 is plottable height
// 400 is plottable width, 39 bars
int displayChartHeight = 300;

Visual C++ :: Nim Project - Not Displaying Matches But Display Correct Number
Apr 9, 2013I am having one issue with my project. We are making a game of Nim code.I'm 99% done with it, i worked hard on it and i feel like i did a good job, however my project is not displaying the matches i want. For example, it display's the inital number of them 23. But once the first player subtracts a number, it doesn't display matches for player 2, just the number of matches remaining. Then as i keep running the program the same thing happens. This is what it's supposed to
output:
"Input/Output sample
WELCOME TO NIM
------- -- ---
Enter the starting player's name (no spaces)-->John
Enter the second player's name (no spaces)-->Mary
There are 23 matches.
ooooooooooooooooooooooo
|||||||||||||||||||||||
Player John please enter the number of matches to remove-->2
There are 21 matches.

Visual C++ :: How To Create Image Buffer In MFC
Jan 27, 2013how to create, initialize, and maintain a memory device context that works as a local buffer for images? The idea is to maintain some large images in local DCs and bitmaps, and only bitblt them to screen in OnDraw().
What I did so far was was to define CDC and CBitmap objects as members of my View class, and then tried to initialize them with the sequence that begins at "// Initialize buffer". I placed that sequence in either OnInitialUpdate, or PreCreateWindow, or OnPrepareDC, or the view constructor, to no avail. The code always crashes in OnDraw, and I've noticed that the m_hDC member of myDevice is zero at that point.
Obviously, the initialization is wrong and MFC does (too many) things in the background which I'm not aware of.... My question was where can I read about that?
Code:
class CMyView : public CScrollView {
// ...
CDC myDevice;
CBitmap bmp;
CBitmap *oldbmp;

Dec 26, 2013I am working on a Windows application using Visual Studio 2012. One of the screens have a text entry field for the user. Instead of using a standard text field control, am placing a image which looks exactly like a text field. Now what i want to do is, capture the key stroke and update this image with the characters entered by user.
The initial image shown to the user is "Blank_Text_Entry.png" and this is added to the resource as IDB_BLANK_TEXT_ENTRY.
This is a rectangular white image with dimensions 153 x 27, with a size of 250 bytes.
My goal is to be able to update this image dynamically based on key strokes by user and display it.
Visual C++ :: Program To Resize Image?
Feb 19, 2013I am currently working on problem set 4 for Harvard's online CS50 course. I am working on a program that resizes a bmp image by a factor of N. N in entered along with an in-file and out-file in a command line argument. The program needs to calculate the header file for the out-file and write it to the out-file. It then needs to actually resize the image and, again, write to the out-file.
The first question I have relates to the header file, here is my code for calculating the header file:
bi2.biHeight = bi.biHeight *n;
bi2.biWidth = bi.biWidth *n;
int padding = (4 -(bi.biWidth * sizeof(RGBTRIPLE))%4)%4;
bi2.biSizeImage = (bi2.biWidth * sizeof(RGBTRIPLE) + padding) * abs(bi2.biHeight);
bf2.bfSize = sizeof(BITMAPFILEHEADER) + sizeof(BITMAPINFOHEADER) + bi2.biSizeImage;
And here is my code for writing the new header file (bi2 and bf2) to the out-file:
fwrite(&bf2, sizeof(BITMAPFILEHEADER), 1, outptr);
fwrite(&bi2, sizeof(BITMAPINFOHEADER), 1, outptr);
At this point I need to actually resize the image. As far as I can tell there are 2 ways to go about this you either have to use an array to store each line you want to print repeatedly (and then you can just write it repeatedly) OR you have to move the pointer back in the input stream and repeat the read/resize/write process each time you need to print the row.
It is this that I am stuck on, first of all, I am not sure what system would be better for resizing the image, although I am leaning towards using an array, and regardless, I don't even know where to begin when in implementing either.
So what I am asking for is, first of all, just a "double check" to make sure my header code makes sense. And second of all, a push in the right direction for actually resizing the image. Here is my complete code:
/****************************************************************************
* resize.c
*
* Resizes a BMP piece by piece, just because.
***************************************************************************/
#include
#include
#include "bmp.h"
int main(int argc, char* argv[]) {
// ensure proper usage
if (argc != 4) {
printf("Usage: copy N infile outfile

Visual C++ :: Updating Image On A Button
Aug 2, 2013I have created an application that has bunch of buttons on top and i want to change the image when I click on the button. But unfortunately I can't get it to work.
Here is the code:
if (serialPort1.IsOpen) {
tsbCommPortOpenClose.ToolTipText = "Open serial port";
closeCommPortToolStripMenuItem.Text = "Open serial port";
tsbCommPortOpenClose.Image = Image.FromFile("Red.bmp");
serialPort1.Close();
[Code] ....
The second one which changes the image to "image2" works fine. Here is the definition of image2:
namespace Regress;
...
private Bitmap image2;
System.Reflection.Assembly myAssembly = System.Reflection.Assembly.GetExecutingAssembly();
StreammyStream = myAssembly.GetManifestResourceStream("Regress.Sharing.gif");
image2 = new Bitmap(myStream);
When I do the same with the other image that I want to use, it won't work! I opened the project properties and added the image into the resources too, and it still doesn't work. It fails and says the file was not there. I've put a copy of the file in the root directory and one in "Resources" folder but it still doesn't work.
