# cyVectorToRasterYRes

This is a read and write property.

This property controls the vertical resolution at which presentations and vector graphics are converted. The default value is `0`, which means HTML Export retains the original resolution.

This property is set in conjunction with cxVectorToRasterXRes.

You can specify the resolution as an absolute size in pixels, or as a proportion of the original size.

KeyView always maintains the aspect ratio of the original graphic and does not increase the resolution. If you set values that would enlarge a graphic, KeyView only changes the size of the HTML element.

To set the resolution in pixels

To specify the resolution in pixels, specify the width (`cxVectorToRasterXRes`) and/or height (`cyVectorToRasterYRes`).

To export the largest image that fits within a bounding box, without changing the original aspect ratio, set both the width and height. For example, to export the largest image that fits in an 800x500 bounding box:

    cxVectorToRasterXRes=800
    cyVextorToRasterYRes=500

Alternatively you can fix one of the dimensions. Set one value and set the other to zero. For example, to export images with a height of 1500 pixels and whatever width is necessary to maintain the original aspect ratio:

    cxVectorToRasterXRes=0
    cyVextorToRasterYRes=1500

The maximum size permitted for either dimension is 4000 pixels.

To set the resolution proportionally

To set the resolution proportionally, set `cxVectorToRasterXRes` to a negative value. A negative value represents a percentage of the original resolution. Set `cyVectorToRasterYRes` to `0` (zero). Negative (percentage) values for `cyVectorToRasterYRes` are ignored.

The following example exports a graphic at 50 percent of its original resolution:

    cxVectorToRasterXRes=-50
    cyVectorToRasterYRes=0
