### Data Structures
`RGBAPixel`
`ImageDataStruct`
```cpp
struct RGBApixel {
unsigned char r = 0;
unsigned char g = 0;
unsigned char b = 0;
unsigned char a = 0;
};
```
```cpp
struct ImageDataStruct {
RGBApixel * imgPixArray;
int imgWidth;
int imgHeight;
};
```
### Methods
`int readImage(std::string);`
`int writeImage(std::string);`
`RGBApixel getPixel(int,int);`
`ImageDataStruct getImageDataStruct();`
`int setPixel(int,int,RGBApixel);`
`int setImageDataStruct(ImageDataStruct);`
`int resizeImage(int, int);`
`int crop(int, int, int, int);`
`int binary(int);`
`int grayscale();`
*reading the image file*
```cpp
IProc ip;
ip.readImage("path/to/source/file.jpg");
```
*getting the pixel value*
```cpp
// pixel in the position (x, y)
RGBApixel pix = ip.getPixel(10,10);
```
*set a pixel value*
```cpp
// set the pixel at position (x, y)
RGBApixel pix;
pix.r = 100;
pix.g = 100;
pix.b = 100;
pix.a = 255;
ip.setPixel(10,15,pix);
```
*get the pixel map of the image*
```cpp
ImageDataStruct imgData;
imgData = ip.getImageDataStruct();
// printing the height and width of the image
std::cout<<"Image height: "<
#include
int main() {
IProc ip;
ip.readImage("imgs/JPEG/input/img5.jpg");
int x = 10, y = 10;
RGBApixel pixel = ip.getPixel(x, y);
std::cout <<"Image("<> Image(10,10) = RGBA( 255 255 255 255 )
>> image height: 250
>> image width: 250
