# wasmCV
Generated Go bindings for wasmCV WebAssembly interfaces to computer vision systems.
See https://github.com/wasmvision/wasmcv for information about wasmCV.
## How to use
This example Go module exports a `process()` function to the WASM host application. When the host calls the processor, it passes in the wasmCV image `Mat` to be processed. The wasmCV module then calls functions on that `Mat` which are handled by the host application, by calling OpenCV to actually perform the operations.
```go
package main
import (
"github.com/hybridgroup/mechanoid/convert"
"wasmcv.org/wasm/cv/mat"
)
//go:wasmimport hosted println
func println(ptr, size uint32)
//export process
func process(image mat.Mat) mat.Mat {
println(convert.StringToWasmPtr("Cols: " +
convert.IntToString(int(image.Cols())) +
" Rows: " +
convert.IntToString(int(image.Rows())) +
" Type: " +
convert.IntToString(int(image.Mattype()))))
return image
}
```
Install the `wasmcv` package into your Go package:
```shell
go get wasmcv.org/wasm/cv
```
You can then compile this module using the TinyGo compiler.
```shell
tinygo build -o processor.wasm -target=wasm-unknown processor.go
```
Note that the `wasm-unknown` target can be used with wasmCV to produce very lightweight guest modules. The example above compiles to around 31k, including debug information.
```shell
-rwxrwxr-x 1 ron ron 31248 sep 11 11:00 processor.wasm
```
