The documentation says that it is in reference to level0. Does it mean that if I am retrieving image data from higher levels I have to always map the coordinates to level0 and then make a call? If so, how does this work if the exact mapping does not work. By that I mean, let’s say the downsample for level1 is 4. If I make a call openslide_read_region(slide, buf, 0, 0, 1, 1, 1) I know I will get an approximate aggregate of 4x4 grid of level 0 starting at 0, 0. However I’m not sure what will a call like openslide_read_region(slide, buf, 2, 2, 1, 1, 1)? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks for the help. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>-Sriram<o:p></o:p></p></div></body></html>
