yagitoshiro / imageasresized Goto Github PK

i've tried this code.

var rate = blob.width / 1024;
blob = androimage.cameraImageAsResized(blob, blob.width / rate, blob.height / rate, 0);

but this did not work as i expected, it croped the image.
the source image is 3264x2448.

this code did not work also.

blob = androimage.cameraImageAsResized(blob, 1024, blob.height * (1024 / blob.width), 0);

this code worked fine.

blob = androimage.cameraImageAsResized(blob, blob.width / 2, blob.height / 2, 0);

i want to limit the image width.
how do i fix this issue?
ImageAsResized v0.5, Titanium SDK 3.1.1.GA

I want to resize and crop a picture in Titanium 3.2, but I ran into a out of memory-error on devices where photos are too big. I was recommended to check this module out. I'm however running into some problems:

var resized_image = e.media;
var rate = 16;
var width = e.cropRect.width / rate;
var height = e.cropRect.height / rate;
resized_image = image_module.cameraImageAsResized(resized_image, width, height, 0);
savedImage = resized_image.imageAsThumbnail(400,0,0);
picture.image = savedImage;

I'm using imageAsThumbnail afterwards to make sure that I'm getting a correctly cropped and sizes image, that will later be sent to an API. However, when I'm doing this I get the following message: RuntimeException: Canvas: trying to use a recycled bitmap

Is there a way to fix this?

When I am using the module and want to resize an image, I get the following error in the Android Monitor:
06-26 14:27:34.154: D/ImageasresizedModule(18881): (KrollRuntimeThread) [97,36079] Bitmap IOException:java.io.FileNotFoundException: file:///mnt/sdcard/app_identifier/preview__tifile54854tmp.jpg

The file path I specify as a parameter is the one returned by calling Ti.Filesystem.File.nativePath. If I call the method with Ti.Filesystem.File.resolve() I get the same error.

At first I thought it might be missing permissions, but in the Android manifest the entry: is set.

I am using Titanium 3.1.0.GA. If this error is not related to the module, could you provide me any hint how I could solve this issue?

Hi,
I think I now why you code sometimes doesn't work. BitmapFactory.decodeByteArray returns smaller image if you pass inSampleSize >1. however later you still use original dimensions to crop the image. You need to recalculate x,y,w,h that you use for cropping (Bitmap.createBitmap) for the new smaller resolution. The matrix in Bitmap.createBitmap happens after the crop and can scale image further. the scale passed to the matrix can be float and works without any issues. But that scale has nothing to do with the crop dimensions you pass to the function.

thank you for your module. I was able to learn from it and write my custom one that does just one thing - centre crop and scale to desired resolution (to create square thumbnails in one operation). Without your code I wouldn't have a clue where to start.

Bitmap image_base = BitmapFactory.decodeByteArray(image_data, 0, image_data.length, opts);
        Matrix matrix = getScaleMatrix(opts.outWidth, opts.outHeight, image_base.getWidth(), image_base.getHeight());
        if(rotate > 0){
          matrix.postRotate(rotate);
        }

        //width, height etc passed here are form original image not scaled down image_base.
        return returnBlob(opts, image_base, matrix, width, height, x, y);

Hello,

I found a problem when trying to compile and use your module.
I had a license issue, telling that I was not allowed to use that module because I was not subscribed.

I solved the issue changing the guid in the manifest.

I presume you are using the same guid for this Open Sourced version and the compiled version in Appcelerator MarketPlace.

Hi there,

Thanks very much for this library it has been a lifesaver!

One problem I am experiencing is that the image doesn't appear to get resized to the dimensions I specify.

For example the following original image is 3264 x 2448:

And when I resize to 450 x 338, it actually goes to 1479 x 1110.

Do you know why this would be? I am using the following method:

resizedImage = androidResizer.cameraImageAsResized(args.media, newImageWidth, newImageHeight, 0);

Thanks in advance, Carl

Looks like Android has this on the newest SDK versions as well: http://docs.appcelerator.com/titanium/latest/#!/api/Titanium.Blob-method-imageAsResized

What is the correct syntax for entering the module into the tiapp.xml file? eg:

imageasresized

My error is:

I need a license to use this module ?, thanks..
