Coding
Please customize util/ImageReader.m for easy coding.
Initialization
#import "ImageReader.h"
call npeInitializeImageLibrary() once.
npeInitializeImageLibrary();
Create a UIImage with Main Bundle
NSString *path = [[NSBundle mainBundle] pathForResource:@"test.png" ofType:@""];
UIImage *image = [ImageReader createUIImage:path];
Create a CGImageRef with Main Bundle
NSString *path = [[NSBundle mainBundle] pathForResource:@"test.png" ofType:@""];
CGImageRef image = [ImageReader createCGImage:path];
Create a PixelImage with Main Bundle
support dds/psd/tga only
NSString *path = [[NSBundle mainBundle] pathForResource:@"test.tga" ofType:@""];
NetNpeImagePixelImage *image = [ImageReader read:path];
Create a UIImage from a PixelImage
NetNpeImagePixelImage *pixelImage = ...;
UIImage *image = [ImageReader createUIImageFromPixelImage:pixelImage];
Create a CGImageRef from a PixelImage
NetNpeImagePixelImage *pixelImage = ...;
CGImageRef image = [ImageReader createCGImageFromPixelImage:pixelImage];
Customize memory management
customize allocateMemory/freeMemory methods if needed.
+ (void *)allocateMemory:(size_t)size {
return malloc(size);
}
+ (void)freeMemory:(void *)memory {
free(memory);
}
