Coming up pretty soon, Android will require apps to be 64bit.

Hi,

Let me check about the license.
Beyka-san is written as
https://github.com/Beyka/Android-TiffBitmapFactory/issues/7

In future I will try to remove GPL code from project to use MIT license

Is it MIT license now?

If it is not MIT license,
what does "licences = ['MIT']" in build.gradle mean?

Regards.

I have a question when I used the old demo; error log is

Hi Team,
Getting bmp value null for below implementation.

String filePath = "file:///data/user/0/com.app.doctor/cache/com.ciscowebex.sdk.downloads/thumb-c0d0e7e6-0e90-43e6-b36a-2ad684b0f5fd-file_example_TIFF_1MB1402900616ORIGINAL_Aircraft_Rescue_Firefighting_training.tiff";

Bitmap bmp = TiffBitmapFactory.decodePath(filePath);
imageView.setImageBitmap(bmp);

kindly help me with this.

I am comparing results of CCITTFAX4 compression of the same black-and-white 59 KB PNG scan file converted to TIF using TiffBitmapFactory against Imagemagick (Windows platform). TiffBitmapFactory gives a 107 KB file while with Imagemagick it is just 43 KB.
Can that be because NativeTiffSaver.cs seemingly only implementing a 1 row per strip for TIFFS?
Would appreciate any insight.

I have experienced a permanent OutOfMemory calling this method:
TiffBitmapFactory.decodePath(path);

It happens only on the following devices that I use to test Android 4.:

• Android 4.1.2 device (Galaxy Win)
• Android 4.4.2 (PadFone S - PF500KL)

This is the stack trace of the java.lang.OutOfMemoryError:

android.graphics.Bitmap.nativeCreate (Bitmap.java)

  | android.graphics.Bitmap.createBitmap (Bitmap.java:817)
  | android.graphics.Bitmap.createBitmap (Bitmap.java:794)
  | android.graphics.Bitmap.createBitmap (Bitmap.java:761)
  | org.beyka.tiffbitmapfactory.TiffBitmapFactory.nativeDecodePath (TiffBitmapFactory.java)
  | org.beyka.tiffbitmapfactory.TiffBitmapFactory.decodePath (TiffBitmapFactory.java:157)

I succeeded to avoid the OutOfMemory crash by setting this attribute of Options:
options.inAvailableMemory = 20000000;

But the returned Bitmap is null.

How can I find a runtime value of options.inAvailableMemory that will work without returning a null bitmap?

Should I use this information?

Hi,
Thank you for this great library.
I am using it with Graddle: compile 'com.github.beyka:androidtiffbitmapfactory:0.9.7.2'
My Compile SDK version is 21 and targetSdkVersion is 19.

It is working fine on my Nexus 9 runnig Android 7.1.1 that I use for testing when I run my app in debug mode.
When I generate a signed apk in release mode, it fails with the following error code.

hi is there an option where i can create a multi paged tiff depending on the number of png images?

Hi, I have a problem when running in a Moto Droid Turbo 2:

Any chance someone could explain me what is missing?

Thank you for your time.

The TiffConverter retuns false. I have provided the input bmp path and output tiff path . and i get 8-byte image in the destination folder. where as the bmp file is around
300kb.

Is it possible to create multi page tiff image using this library ?

I see a lot of chatter back in 2020 but nothing this year. Is this project now deprecated/unsupported?

Please help me!

Can you please tell me why the LZWcompression is generating images less compress that CCITTFAX4, since we need the best compression without lossing the quality.

Hi i am trying to convert tiff to jpeg format but my output is showing last captured image only,how i get both files converted,
and also please help me to convert tiff to base64 format

do you have a link to the library already compiled and ready to add to a android project?

Hi!
Recently I upadted to the last version com.github.beyka:androidtiffbitmapfactory:0.9.7.4, but when I try to save the JPG image to Tiff isn't converting like the older version. Attached you will find the original and how is converted. Also here is the code I'm using it.

                  //Open some image
                  debugLog("Loading jpgBitmap ..");
                  Bitmap jpgBitmap = loadImage(resultImgUri.toString());

                  if(jpgBitmap != null) {

                    debugLog("jpgBitmap loaded");
                    //Create options for saving
                    TiffSaver.SaveOptions options = new TiffSaver.SaveOptions();
                    //By default compression mode is none
                    options.compressionScheme = CompressionScheme.LZW;
                    //By default orientation is top left
                    options.orientation = Orientation.LEFT_TOP;


                    //Add author tag to output file
                    options.author = "UPS";
                    //Add copyright tag to output file
                    options.copyright = "UPS Copyright";

                    //Save image as tif. If image saved succesfull true will be returned
                    debugLog("start saving tiff");

                    File tiffFile = sdkWrapper.generateTifFile();

                    boolean saved = TiffSaver.saveBitmap(tiffFile, jpgBitmap, options);

                    debugLog("finish saving tiff");

Please advice!!

Output image file when saved as .tif then its resolution size saved to small size. 3000X4000 images are saved in 183X250 with file size 184kb. I want to save in same resolution as image is taken.

First, I want to thank you for such a great and useful library :) it is an excellent job.

I just recently needed to convert a TIFF image to PNG, and found that it can be done using TiffConverter.convertTiffPng().

I proceeded to run such method, providing the default ConverterOptions and without listener (null). After the process finishes, the .png image is successfully (no errors thrown, correct height/width) converted, but it is different than the original .tiff image.

The way it is different is that, in the pixels where there should be nodata values (transparent) they seem to "take the pixel value" of nearby pixels. In other words, in a pixel where it should be nodata, it has the value of (say) the pixel N units above it, like it were "filling" the nodata values with the closest chunk or region of pixels closest to the nodata chunk.

Funny analogy: it looks really similar to when you dragged your window on the screen and it "lagged", leaving a trail among the path (which was a copy of one of the edges of the image), on old Windows OS.

Here are some more technical specs (if more are needed will provide them gladly):

• Library Version: 0.9.8.7
• Using Android Studio, with Kotlin
• Using Gradle to get the dependency.
• Device: Samsung Galaxy Tab A

Also, did some testing with other images, and found that other, smaller images are converted without this issue. For example:

-Image without issue: 2334x2154, 20.1MB
-Image without issue: 3830x3999, 61.3MB
-Image with issues: 4862x5065, 99.6MB
-Image with issues: 13225x7753, 415.8MB

Both have the same Spatial Reference (WGS84), nodata values, etc., so perhaps the issue has something to do with the size (fails somewhere between 61-99 MB) or the dimensions (perhaps the ones greater than 4096 on either width or height?).

Thanks in advance, and if you need anything else I'll gladly provide.

Hi Aleksey,

First of all, thanks for the effort Implementing on version 0.9.6 Group 4 compression.

I have a problem, but I guess it is not related to this version (as it happens also on 0.9.5 for me). Testing TiffBitmapFactory on the emulator works fine but when I try to do it in the mobile, i get an error during saveBitmap in the line System.loadLibrary("tiff")

The mobile is an Android 6.0 MTK6580 Quad-Core

any help? Please...

Only applications should define this attribute. They need to decide whether they want to allow users to backup their app, and if it's true, what to back up. Please remove this attribute so that it doesn't leak into applications: imagine if an app doesn't declare this attribute, but it uses your library. They'll have their allowBackup set to some value they didn't decide on.

In our case we were lucky that we defined the value and it conflicted yours, so we were alerted to the change.

> Task :app:processReleaseManifest FAILED
app/src/main/AndroidManifest.xml:11:9-36 Error:
        Attribute application@allowBackup value=(false) from AndroidManifest.xml:11:9-36
        is also present at [com.github.beyka:androidtiffbitmapfactory:0.9.8.7] AndroidManifest.xml:12:9-35 value=(true).
        Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:9:5-26:19 to override.

Note: we didn't even use this tiff library, we got it through a transitive dependency!
We just added implementation("com.thirdparty:library:1.2.3") and it pulled in this tiff library:

+--- com.thirdparty:library:1.2.3
|    +--- ... lots of other dependencies
|    \--- com.github.beyka:androidtiffbitmapfactory:0.9.8.7

There's no easy workaround for this other than every single user of your library and every single user of any library that depends on yours having to be aware of this leaked allowBackup attribute and use tools:replace.

How to build project for signed apk?. When I generate signed apk. It doesnt install on device. Im thinking about this is occurring because the library didn't build for release. How can i build for release mode?

Hi!,

I'm trying to use the decode process, but returns null the bitmap.

File file = new File("/storage/emulated/0/Android/data/Temp/50a.tif");

TiffBitmapFactory.Options options = new TiffBitmapFactory.Options();
options.inJustDecodeBounds = true;

        Bitmap bmp = null;
        bmp = TiffBitmapFactory.decodeFile(file, options);

Can you please tell me if I missing something.

tiffTest111.zip

I dont know why this picture cause crash ! can you give me some suggest?

Branch x64-support has supporting for all abies.
All who can test this branch on real device with abi arm64-v8a, x86_64 please do this.
Building of native is described in readme file of master branch.
If all works good please leave comment to this issue with next data: Device(nexus, smasung etc.), Abi(arm64-v8a, x86, etc.), API version or name (API21 or Lollipop, etc). is all compression mods from TiffSaver.CompressionMode works while saving and is TiffBitmapFactory can open saved files or else tiff images.
For now it tested on real devices with abi armeabi-v7a and x86 and emulators with abi arm64-v8a, x86_64, mips.
Thank you. After testing new build will be available in repositories

Hi ,
i am merging 2 jpeg files to single tiff file. but the property of tiff file Photometric Interpretation is coming as RGB but in jpeg Photometric Interpretation is coming null

please help to remove the Photometric Interpretation value while creating the tiff file

Hi,

I tried to read a gray scale tiff image with RGB_565 image config option because the image pixels in stored in two bytes (16bit), when i read pixel value from the bitmap the value doesn't seem to be an elevation value.

how can i use the library for reading such files ? below is example:

TiffBitmapFactory.Options options = new TiffBitmapFactory.Options();

options.inJustDecodeBounds = false;
options.inPreferredConfig = TiffBitmapFactory.ImageConfig.RGB_565;
options.inDirectoryNumber = 0;

Bitmap bmp = TiffBitmapFactory.decodeFile(file, options);
bmp.getPixel(1800, 3400);

This is my code, and i can only find one image in the tiff file.
java ArrayList<String> fileArray = new ArrayList<>(); fileArray.add("/sdcard/Pictures/edu.jpg"); fileArray.add("/sdcard/Pictures/beifeng.jpg"); fileArray.add("/sdcard/Pictures/tashigan.jpg"); for (int i = 0; i < fileCount; i++) { Bitmap bitmap = BitmapFactory.decodeFile(fileArray.get(i)); TiffSaver.SaveOptions options = new TiffSaver.SaveOptions(); options.compressionScheme = CompressionScheme.NONE; options.orientation = Orientation.LEFT_TOP; options.author = ""; options.copyright = ""; boolean saved = TiffSaver.saveBitmap(filePath + File.separator + fileName, bitmap, options); }
Does some one also have this problem?

sorry for my poor English.

In x86_64 Device, Some Tiff has image noising.

x86 device)

x86_64 device)

How can i fix it? Should i write some code to fix it??

I am calling:

TiffSaver.saveBitmap(file, bitmap);

Bitmap is a gif image loaded with Android's BitmapFactory.decodeStream. It seems that everything is fine with the gif image as it is properly decoded and encoded to other formats supported natively by Android.

However, the call results with the following error:
A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 3220 (Thread-2250)

The error can not be caught with a catch clause in java code, the app just crashes immediately. I am attaching the gif file:

on every meizu device i got the error : org.beyka.tiffbitmapfactory.exceptions.NoSuchFileException
The native method TIFFOpen(strPath, "w") always returns null.
do you know this kind of issue?

Hi,
Thank you so much for the awesome library. Unfortunately when I tried to get bitmap from a tiff file using TiffLoader.getBitmap(int dir,int sampleSize) , but the color of the bitmap is changed from red to blue. I checked the config it is ARGB_8888. Can you please suggest a solution on this issue?

There's a version 0.9.8.8 artifact available on bintray - https://bintray.com/beyka/maven/androidtiffbitmapfactory/0.9.8.8 - but I can see no traces of that in this source repository here.

What's up with that?

The above are executed still I'm getting the following error:

Hi Beyka,

I am now having issue getting decodeFile to work. I used a test Tiff (1640x1240), set options.inJustDecodeBounds = true, and called decodeFile(file, options). There was no exception, but the Bitmap returned was null.

I then tried importing your source as module (not from gradle), but same result. However, android studio warned that it could not resolve corresponding JNI function of nativeDecodePath in TiffBitmapFactory.java.

I am using NDK 10e for the native code compilation (which also warns of non-system libraries in linker flags for libjpeg-x86.a and libjpeg.a.

Do you know how I can resolve this issue?

Thanks,
Devin

Is arm64-v8a supported?

Hi again :) how to delete appended bitmap on created tiff file?

Is it possible to convert Raw Data from camera feed into Tiff 16 bit linear version? I have a requirement to convert the raw output of the camera into Tiff format. Will that be possible with this?

Hi,

I was using your excellent library since many many months ago. After relaunching the app I was developing and updating to the latest version of the library (I was using 0.9.7.5 or lower), I found that the conversion of a single JPG is not ok.
I´m getting a noise unreadable image.

I´m using the piece of code explained in the example and tutorial. And I hardly beleive that this piece of code was working before...

any help?

Hi , is there any possibility to use this great library for commercial use ?

Because the problem is the gpl license.

 I am converting jpg image to tiff group 4 format with 96 dpi & 2000 x 40000 resolution using this library, but the output tiff file size varies for different mobile devices. Is there any possibility to reduce the tiff image size(lesser than 200kb) without reducing height and width?

Hi!
I am building an Android App and I need to compress an image in group 4. But I am not seeing the option in TiffSaver.CompressionMode. Is there any way I can call COMPRESSION_CCITTFAX4 ??

Fatal signal 8 (SIGFPE), code -6, fault addr 0xee5 in tid 4032 (Worker Thread)

How can i handle this?

Hi,

I noticed that I was creating an application using this library.
If you import a file compressed in fax format (CCITT), it will introduce noise.
A similar phenomenon was also seen in "B Tiff Viewer" you developed.

The files used are as follows

• G31DS.TIF
• G32DS.TIF

Please tell me how to eliminate the noise.

Hi Beyka,

I am having issue using your module. I tried to install it through gradle dependencies (compile 'com.github.beyka:androidtiffbitmapfactory:0.6'), then following the usage sample you wrote. However, I couldn't access the options properties or decodeFile in the TiffBitmapFactory object. Do you know what could be the issue?

Thanks,
Devin

According to JFrog, the JCenter repository ceased serving packages on February 1st 2022, which means your library is no longer accessible and now gives the following error in when syncing Gradle dependencies in Android Studio: "Failed to resolve: com.github.beyka:androidtiffbitmapfactory:0.9.8.8"

The artifact is still searchable in Maven, giving the URL https://mvnrepository.com/artifact/com.github.beyka/androidtiffbitmapfactory/0.9.8.8
However, the link to the library on JCenter https://jcenter.bintray.com/com/github/beyka/androidtiffbitmapfactory/0.9.8.8/androidtiffbitmapfactory-0.9.8.8.aar gives a 403 Forbidden error, confirming that the JCenter repository has been closed down.

Can you advise if you are intending to migrate the library to MavenCentral to keep your library alive, or perhaps make the library available as a direct download from the GitHub repository.

Thanks in advance.

We use com.sun.imageio.plugins.jpeg.JPEGImageReader to decode the TIFFs we receive in one portion of our app. I'm using TiffBitmapFactory to generate multipage grayscale TIFFs and using CompressionScheme.COMPRESSION_JPEG when saving them. JPEGImageReader is complaining about an unsupported image type, and the one that it's getting from the image is com.sun.imageio.plugins.jpeg.JPEG.JCS_CMYK, which it doesn't handle.

Is there a way to make TiffBitmapFactory emit RGB? Alternately, could TBFactory be outputting CMYK because of anything I'm doing?
