Openslide不会显示level_count-1的mmpx属性

Question

属性“ openslide.mmp-x”显示的属性包含级别0的X维度中每个像素的微米数。正如我正在显示的level_count-1，我不希望级别0的属性，但希望level_count的属性-1。如何获得该级别的属性？

slide = openslide.OpenSlide(SVSFileName)

# get width, height of image at low-res reading magnification
lrHeight = slide.level_dimensions[slide.level_count - 1][1]
lrWidth = slide.level_dimensions[slide.level_count - 1][0]

mmx = slide.properties['openslide.mpp-x']

Answer 1

slide.level_downsamples

-> (1.0, 2.0, 4.0, 8.0)

给出电平如何进行下采样，我想我们可以通过下采样度来计算mpp-x / mpp-y。
