Image Processing
The processing package provides the function TransformImage which takes an Image, and Kernel structs as parameters and returns a pointer to RGBA struct.
TransformImage Type Declaration
func TransformImage(i image.Image, k *kernels.Kernel) *image.RGBA
Image and RGBA structs are provided by the image package from the standard library. Kernel on the other hand is supplied by the kernel package of this library.
Supported Formats
Three formats are supported by the processing package (png, jpeg and jpg). The formats package supplies the function IsSupportedFormat which takes a string and returns a boolean value.
Kernels
Four basic kernels are provided by the kernel package:
Example Transformations
Original Image
Sharpen Kernel
GaussianBlur Kernel
EdgeDetection Kernel
When applied on an image transformation, the resulting image displays the edges of objects in the image.
BoxBlur Kernel
Custom Kernel
A custom kernel can be used by implementing the Kernel struct from the kernels package. This struct contains the field Kernel which is a three by three matrix of float32 values.
