A bitrate of 0 indicates that all the quantized data should be included in the image. This creates lossless images if the R53 wavelet is chosen Sets the output image bitrate, in bits per pixel. “ –set-output-j2k-bitrate 0” Quoting from the “AccuRad J2KSuite Developer’s Guide”: “Sets the output image bitrate, in bits per pixel.“ –wavelet-transform R53” specifies use of the reversible “integer 5-3 filter” (compression) to produce a losslessly encoded JPEG2000 file.EPH to enable End of Packet Header markers.“ –set-output-j2k-error-resilience ALL” This function will take the following parameters, each explained below by Aware’s Alexis Tzannes.Applying compression to YUV data is more efficient, yielding smaller files than the same compression applied to the unconverted RGB data. This conversion is made prior to compressing the data. The transform referred to here is a colorspace transformation from RGB to YUV. “ – set output-j2k-color-xform YES” I believe that one does not need to call this option explicitly YES seems to be the default value.“ –set-input-image” reads file into the encoder’s memory-buffer and auto-detects the input file format.Too guard against over-compression, we have developed an effective method for dynamically resetting the db value if the file appears to have been too heavily compressed. There are cases (certain kinds of photographs, illustrations with fine thin lines) where a 46 db setting would produce a too heavily compressed file. When we set the pSNR value to 46 db for the page-images that we create, we’ve come to expect a very high-quality encoded image. “ –set-output-j2k-psnr 46” The pSNR function was selected because it effectively, although imperfectly, modulates the level of compression applied to each image based on the image’s particular characteristics: the arrangement and variability of raster values.“–wavelet-transform I97” specifies use of the “irreversible 9-7 filter” to produce a lossy encoded JPEG2000 file.J2kdriver.exe –-set-input-image-file –-set-output-j2k-color-xform YES –-set-output-j2k-error-resilience ALL –-wavelet-transform I97 –-set-output-j2k-progression-order RLCP –-set-output-j2k-psnr 46 –-tile-size 1024 1024 –output-file-type JP2 –-output-file-name J2kdriver.exe –-set-input-image –-set-output-j2k-color-xform YES –-set-output-j2k-error-resilience ALL –-wavelet-transform R53 –-set-output-j2k-bitrate 0 –-set-output-j2k-progression-order RLCP –-tile-size 1024 1024 -–output-file-type JP2 –-output-file-name Lossy encoding We streamline the process it takes to make the right decision on technology and services and reduce the cost and time it takes to deploy.Lossless encoding We pride ourselves on knowing the real needs of all parties. Today J2K is growing by always doing the right thing for our clients and partners. Our clients include some of the fastest-growing businesses in the tri state area. We also helped save time and money spent on acquiring technology using our TALM method. We have saved 10’s of millions of dollars in software maintenance and renewal cost. Our clients range from SMB to fortune 1000 clients.įast forward, we have grown into a solutions and services provider with a strong focus on cost reduction for our clients. This quickly morphed into J2K representing vendors into the NY, NJ, CT, and PA markets. Our company started out advising software companies on how to understand the needs of clients. We are self funded and answer to no investors. J2K is a family owned business with decades of experience in enterprise and SaaS business models.
