Is there a Java library for rotating JPEG files in increments of 90 degrees, without incurring image degradation?

Suppose the relation R( K, L, M, N, P), and the functional dependencies that hold on R are: - L -> P - MP -> K - KM -> P - LM -> N Suppose we decompose it into 3 relations as fol...

I would like to convert 16 bits grayscale images in an HEVC/mkv video with the x265 encoder without loss, using ffmpeg. I use the monochrome12 profile. My first step is to convert images into yuv f...

I want to rotate a 351K PDF named 08-file.pdf using CLI tools. I've tried imagemagick: convert 08-file.pdf -rotate 90 08-file-rotated.pdf But the original quality: Suffered serious degradatio...

My friend told me it existed but I could never find it, not sure if he was lying but I'm very interested as to how the proof works. (Yes, I'm one of those people who found out about Huffman coding ...

I'm trying to concatenate multiple ogg vorbis files into one. I know that theoretically it should be enough to do: cat 1.ogg 2.ogg > combined.ogg But this has disadvantages: not all player...

I'm currently working on the lossless JPEG files(not JPEG-LS). It's really hard to find any files to test my application on. Particulary I need files that contain reset interval markers, multiple ...

I'd like to decode a JSON blob into a Go struct, manipulate on it, and encode it back to JSON. However, there are dynamic fields in the JSON that aren't relevant to my struct and I want to maintain...

I have a program written in C++ which is generating C source code for mathematical calculations. I have noticed that the constants take up very much space in the generated code and am looking for a...

Is there someone that can tell me how to write 'jpeg' file using lossless compression in java? I read the bytes using the code below to edit the bytes WritableRaster raster = image.getRaster(); ...

I need to rotate some existing JPG images. They have already lost some detail, but I now want to rotate them and lose no further detail. With a little research, it seems the only lossless Image ro...

I'm working on a streaming server that will be capable of broadcasting targetted ads. Basically listeners hear the same music, but every, say, 30 minutes comes a block of ads and every listener has...
