Hello I would welcome some features if possible: 1) I would like to load only even rows or only odd rows of image so only half of the image size would be read. I could then implement it as follows: I would use one thread to load odd rows and second thread to load even rows in common row_pointers buffer. I believe this could increase performance twice. 2) in some cases I may want not to load whole image. In the case that I want to copy just small part of the image I am missing some command which would use offset from left and offset from top. E.g. I could skip 100 rows from top and from left edge. Also I could want to skip some rows or columns from the right edge and from bottom of the image. I have such situation when I need this. Now I must load complete image and then to crop it. |
