When using jcopy() to transfer rows between files, be sure to check the source and destination file sizes to ensure they are within a single row. libjpeg-turbo works around this issue by checking that the source and destination row numbers do not exceed the max_endian_row_num setting. If they do, a temporary copy is made, and the row is re-calculated.
One of the most common mistakes made when transferring rows between files is to use incorrect row sizes. Make sure to check the size of each row when transferring between files.
If you receive an error from libjpeg-turbo that looks like this: jcopy_sample_rows() received an invalid row size. This could be caused by a bad row size, or a null pointer dereference, or both. The most likely cause is a bad row size. Make sure to check the size of each row when transferring between files. If you have a null pointer dereference, this could be caused by a bad row size, or a null pointer dereference, or both. The most likely cause is a bad row size. Make sure to check the size of each row when transferring between files. If you receive an error from libjpeg-turbo that looks like this: This could be caused by a bad row size, or a null pointer dereference, or both. The most likely cause is a bad row size.

Common bugs and their solutions
When using jcopy() to transfer rows between files, be sure to check the source and destination file sizes to ensure they are within a single row. libjpeg-turbo works around this issue by checking that the source and destination row numbers do not exceed the max_endian_row_num setting. If they do, a temporary copy is made, and the row is re-calculated.
One of the most common mistakes made when transferring rows between files is to use incorrect row sizes. Make sure to check the size of each row when transferring between files.
Wrapping libjpeg-turbo in a Function
Wrapping libjpeg-turbo in a function is an easy way to avoid the need for constantly checking that the source and destination row numbers do not exceed the max_endian_row_num setting.
A common mistake made when transferring rows between files is to use incorrect row sizes, so wrapping libjpeg-turbo in a function can be an easy way to avoid a lot of work.
Avoiding DSEs when transferring rows with jcopy()
If you receive an error from libjpeg-turbo that looks like this: jcopy_sample_rows() received an invalid row size. This could be caused by a bad row size, or a null pointer dereference, or both. The most likely cause is a bad row size. Make sure to check the size of each row when transferring between files. If you have a null pointer dereference, this could be caused by a bad row size, or a null pointer dereference, or both. The most likely cause is a bad row size.
Make sure to check the size of each row when transferring between files.
