Multiple Image Translation Test Cases

[Avey777]

Is it possible to create a test case that translates multiple images, as the current test file contains cases of translating a single image?

[Avey777]

As far as I understand, I can now transfer multiple image file path strings. However, I can only transfer one image file path. In this case, the code of this branch does not need to be modified, but the translation speed of the second and following images has not changed compared to the previous one.

You can write something like that and I don't see the point in covering it with tests.

package main

import (
    "log"
    "os"
    "strconv"
    "sync"

    languagecodes "github.com/spywiree/langcodes"
    "github.com/spywiree/translateimage"
)

func main() {
    ctx, err := translateimage.NewContext()
    if err != nil {
        log.Fatalln(err)
    }
    defer ctx.Close()

    var wg sync.WaitGroup

    imagePaths := []string{} //Your image paths
    var n int
    for _, path := range imagePaths {
        wg.Add(1)
        n++

        go func() {
            img, err := ctx.TranslateFile(path,
                languagecodes.DETECT_LANGUAGE,
                languagecodes.ENGLISH)
            if err != nil {
                log.Println(err)
                wg.Done()
                return
            }

            data, err := img.ConvertTo("image/png")
            if err != nil {
                log.Println(err)
                wg.Done()
                return
            }

            err = os.WriteFile(strconv.Itoa(n)+".png", data, 0666)
            if err != nil {
                log.Println(err)
            }

            wg.Done()
        }()
    }

    wg.Wait()
}

I have tried this, but it does not guarantee that the output names of the images will be named in the order of the image paths I passed in, which will disrupt the order of my images.

[spywiree-priv]

What do you mean? First file should be named 1.png, second - 2.png and so on.

After debugging for a long time, I still don't understand why the example you gave above only outputs the last picture.

[spywiree-priv]

Ok, here is the fixed version.

package main

import (
    "log"
    "os"
    "strconv"
    "sync"

    languagecodes "github.com/spywiree/langcodes"
    "github.com/spywiree/translateimage"
)

func main() {
    ctx, err := translateimage.NewContext()
    if err != nil {
        log.Fatalln(err)
    }
    defer ctx.Close()

    var wg sync.WaitGroup

    imagePaths := []string{} //Your image paths
    for i, path := range imagePaths {
        wg.Add(1)

        go func(i int) {
            img, err := ctx.TranslateFile(path,
                languagecodes.DETECT_LANGUAGE,
                languagecodes.ENGLISH)
            if err != nil {
                log.Println(err)
                wg.Done()
                return
            }

            data, err := img.ConvertTo("image/png")
            if err != nil {
                log.Println(err)
                wg.Done()
                return
            }

            err = os.WriteFile(strconv.Itoa(i+1)+".png", data, 0666)
            if err != nil {
                log.Println(err)
            }

            wg.Done()
        }(i)
    }

    wg.Wait()
}

Perfect!
