设置 [`ImageOrPrintOptions.horizontal_resolution`](/cells/python-net/zh/aspose.cells.rendering/imageorprintoptions#horizontal_resolution) 和 [`ImageOrPrintOptions.vertical_resolution`](/cells/python-net/zh/aspose.cells.rendering/imageorprintoptions#vertical_resolution) 
影响输出图像的宽度和高度（以像素为单位）。

### 例子

以下代码将分辨率设置为192，生成的图像的宽度和高度是
分辨率保留为默认值 96。

```python
from aspose.cells import Workbook
from aspose.cells.drawing import ImageType
from aspose.cells.rendering import ImageOrPrintOptions

wb = Workbook("Book1.xlsx")
opts = ImageOrPrintOptions()
# Set output image type: png.
opts.image_type = ImageType.PNG
# Set resolution to 192.
opts.horizontal_resolution = 192
opts.vertical_resolution = 192
# Render Chart to image.
wb.worksheets[0].charts[0].to_image("Chart.png", opts)

```
### 定义：
```python
@property
def vertical_resolution(self):
    ...
@vertical_resolution.setter
def vertical_resolution(self, value):
    ...
