Failed read Hamamatsu top level region

[zhaoy at motic.com]

Dear All,

Recently, I found a problem with a Hamamastu NDPI slide (https://med2.motic.com/transfer/slide.ndpi).

The OpenSlide SDK failed to call openslide_read_region at top level region (level[8]), and NULL data returned. The last error message is “Corrupt JPEG data: premature end of data segment”. Other level (level[0-7]) region images can be read by SDK. But the viewer of Hamamastu works fine with this slide. There are some other slides from the same scanner. OpenSlide SDK can read all of them. I don’t know what makes this slide file special.

BTW, does anyone use OpenSlide Windows SDK with no-english file path? According to the API document, the file path parameter should be UTF8 encoded. But I found the openslide_open (g_utf8_to_utf16 in the down layer) failed with a UTF8 string. It only accept OEM codepage encoded char*.

Thanks for help

Regards,

Yu
