Sets the size of image file in the horizontal direction in pixels (number of columns). By setting the X and Y image size properties prior to getting a reader for the data, the client application can control the density of pixels fetched by the provider, which may reduce the amount of data shipped by the reader and reduce processing time significantly. For example, a certain query in the coordinate system of the raster object class returns a FdoIRaster object with image size 12091 by 8043. But the image only needs to be displayed in an area 1167 by 776 on the users monitor.
- Note:
- The aspect ratios are the same because the query is constructed based on the display area).
- Parameters:
-
| size | The desired horizontal image size in pixels (number of columns). |
