XlsChart.GetImageAlternate Method
Returns an image and its type. Currently this method is the same as ExcelChart.GetImage for all images except SVG. For SVG images, xlsx files store both a PNG and SVG image. In those cases, this method will return the SVG image. To get the PNG, call ExcelChart.GetImage
Syntax
Namespace: FlexCel.XlsAdapter
public override void GetImageAlternate(Int32 imageIndex, String objectPath, out TXlsImgType imageType, Stream outStream, Boolean usesObjectIndex)Parameters
| <-> | Parameter | Type | Description |
|---|---|---|---|
| imageIndex | Int32 | Index of the image. (1 based) | |
| objectPath | String | Object path to the image when it is a grouped image. For toplevel images you, can use String.Empty. In other case, you need to use the value returned by ExcelChart.GetObjectProperties If it is "absolute" (it starts with "\"), then the path includes the objectIndex, and the objectIndex is not used. An object path of "\1\2\3" is exactly the same as using objectIndex = 1 and objectPath = "2\3" |
|
| out | imageType | TXlsImgType | Returns the image type for the data returned. (If it is a bmp, jpg or other) |
| outStream | Stream | Stream where the image data will be copied. | |
| usesObjectIndex | Boolean | If false (the default) then imageIndex is an index to the list of images. When true imageIndex is an index to the list of all objects in the sheet. When you have the object id, you can avoid calling ObjectIndexToImageIndex which is a slow method, by setting this parameter to true. |
