With other programs (that are not multithreading) I have achieved running many instances simultaneously by copying the. Especially having all the changes updated on the preview window is by far the difference with other programs. Save the master files into a first output, then the second output to a third, the third into a fourth etc.įirst of all, thank you so much for the immediate responce to my post.Īnd, also, congratulations for this incredible program. It would be a life saver if the xnconvert Output tab could have multiple outputs. The final directory tree looks like this: and finally I am merging the 4 root directories, in order for the subfolders to be placed next to each other. The thumb will have the midres converted to jpeg 72 dpi with 280 pixels for the longest side.įor now, I am doing each batch one step at a time with preserving the folder structure, renaming the output folders "tiff" to"hires" etc. The midres will have the hires converted to jpeg 150 dpi with preserving the print size and qith quality 100% The Hires will have the tiffs converted to jpeg 100% quality, I need one of xnconvert/xnview/nconvert to batch process at once these tiff folders and create the following: next to every TIFF folder, I want to create three folders named So, even though I am familiar to batch processing softwares (like irfanview, xnconvert, photoshop, bridge,lightroom, faststone, blah blah blah), I want to simplify my life by being able to convert a set of images located in a root directory with many subdirectories to many other formats.įor example, let's say I have a directory tree like this:Īll of the above "chris" folders have a subfolder named "TIFF", which contais tiff files. tCompression(CompressionType.Hello everyone, I am a new member of the forum and I have no knowledge of script writing. tColorspace(ColorspaceType.GRAYColorspace) ![]() ImageInfo info = new ImageInfo(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+"/output.tiff") ![]() MagickImage image = omBitmap(sizedImage) I know that it must be possible because there are apps on the Play Store for converting image formats which include converting to TIFF, including one from Paul Asiimwe, who published this Android port.īy using the following code I am able to get an uncompressed TIFF that appears to be correct in all other regards, but it just will not compress it to Group 4 compression. Has anyone used ImageMagick in Android to convert to a TIFF, or does anyone know of a clean method of converting to a TIFF in Android that is verified to actually work. If a call to setMagick("TIFF") is made, then when it reaches image.writeImage(info) the app will crash with the following output: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 2283 I have tried various permutations of the different calls to setMagick and setCompression, all of which yield the same result. tCompression(CompressionType.Group4Compression) The relevant code snippet is: MagickImage image = omBitmap(sizedImage) I am able to use it to convert to a couple different image formats, but when I try to convert to a TIFF I receive a SIGSEGV and the app crashes. So far I have set it up in my app and am able to output the image to a file in order to verify the image. OpenCV I also started to implement, but I decided the requirement to install a secondary OpenCV Manager APK in order to use it is not acceptable for my app, in addition to this being significant overkill for solving a simple problem.Ĭurrently I have been working with the Android port of ImageMagick found here and this appears to be a promising approach. Porting libtiff should work, and I have a branch in my code where I have begun this process, but due to the time required to do this I would prefer an alternate solution. JAI imageio is commonly recommend on here as a possible solution, but I found that even when I found a standalone version of JAI imageio that I still had an unmet dependency on javax.imageio and as a result could not build my app. I have tried several different approaches to convert my Bitmap to a TIFF including using JAI imageio in Android, porting libtiff into NDK and using OpenCV. I am working on a project that has an external API that I need to submit an image through, and the requirement of that API is that the image be a TIFF with Group 4 Compression. ![]()
