How else will we rename the attribute?

Not very urgent since I'm not using it. The jni macro was made as a general jni binding lib though. It'll have to be fixed eventually

CLI: convert input.jpg -deskew 40% output.jpg
IMOps.html#deskew - im4java

          Just want to update you. The reason it fails is because the font isn't available. (The Exception message I showed above will tell you that as well)

looking for a good image format envelope library

Cannot config the project, I followed all steps but I still getting this error when I try to call Magick.initialize(). It wuould be great if you can have a full example project on how to setup it. I assume I miss some configs because I have all those .so files in jniLibs folder as you described in /example folder.

When I try to convert JPG to PDF, it throws an exception in some devices

E kmagick::magick_wand: MagickWand::writeImages() threw an exception: MagickError("failed to write images")

D UnableToCreateTemporaryFile 'magick-_CwoAApjRQXS-O121m7hoaSZ8mdSsJ7y': Read-only file system @ error/blob.c/InjectImageBlob/2772

val wand = MagickWand()
wand.readImage(imagePath)
wand.transformImageColorspace(ColorspaceType.CMYKColorspace)
wand.writeImage("path/xxx.pdf")

Hi, could you please help me to translate bellow cmdline command to kotlin api?

convert ori.jpg -resize 50x100% -geometry x684 -rotate 90 tmp.rgb

below is kotlin code

val wand = MagickWand()

wand.readImage(path)

val width = wand.getImageWidth()
val height = wand.getImageHeight()
wand.resizeImage(width / 2, height, FilterType.BartlettFilter)

// missing geometry code here

val pixel = PixelWand()
pixel.color = "transparent"
wand.rotateImage(pixel, 90.00)

wand.writeImage("tmp.rgb")

I don't sure the code of resize, rotate is correct, bacause when I use Mbrush printer to print the generated tmp.rgb file, but it can't print.

please help me, thank you.

Sorry, I just started using your library.
Got some problems, maybe a little stupid.
After I compile it successfully, some functions can be used, and some functions cannot be used.
These are all JNI problems, I hope you can help me if you have time.

 private fun testColor() {
        if (Magick.isInitialized()) {
            val b = MagickWand()
            val path = "${this.externalCacheDir}/test.png"
            b.readImage(path)
            logD(b.getImageAlphaChannel())
            logD(b.getImagePage())
            logD(b.getImageHeight())
            logD(b.getImageResolution())
            logD(b.getImageHistogram().toString())
        }
    }

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest version
• I checked the documentation and examples and found no answer
• I checked that it wasn't user error; it was not an ordinary exception that I could've found out and fixed by running wand.getException()
• I checked that this isn't an ImageMagick bug itself, and is an actual problem with the bindings
• I checked to make sure that this issue has not already been filed
• I'm reporting the issue to the correct repository

Context

Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

• Android SDK version (if using Android): Android 11.0
• Product (Android Studio, Flutter, etc): Android Studio
• Kotlin version: 1.6.21

A 100% working app example would be far more useful than the current sample directory which is just a repeat of the readme instructions.
I've tried changing the name and location of the jni library folder and location of the .so file (libs, jniLibs, jniLibs/arm6-v8a, res, etc...)

}

below is my code:

coroutineScope {
    texts.forEachIndexed { index, text ->
        launch {
            withContext(Dispatcher.IO) {
                transformAndSaveToTmpRgb(context, text, index)
            }
        }
    }
}

fun String.transformAndSaveToTmpRgb(
    context: Context,
    rootPath: String,
    nameOfTmpRgb: String
) {
    // generate tmp.rgb file
    Thread {
        context.getMagick().use {
            val wand = MagickWand()
            wand.readImage(this)

            var width = wand.getImageWidth()
            val height = wand.getImageHeight()

            val scaleHeight = 684f / height
            width = ((width / 5f) * scaleHeight).toLong()
            wand.resizeImage(width, 684, FilterType.BartlettFilter)

            val pixel = PixelWand()
            pixel.color = "transparent"
            wand.rotateImage(pixel, 90.00)

            wand.writeImage(rootPath + File.separator + "tmp${nameOfTmpRgb}.rgb")
        }
    }

}

when I run above code, it will raise error, and app crash:
--> kmagick::magick_wand: Failed to get handle for MagickWand::writeImage(): Field handle is null

but when I remove launch statement, it will work.

coroutineScope {
    texts.forEachIndexed { index, text ->
        withContext(Dispatcher.IO) {
            transformAndSaveToTmpRgb(context, text, index)
        }
    }
}

it looks very weird.

The method is throwing an error by just trying to use it..
