Image Sparkline

The image sparkline can be used to place an image in a cell. The image can be displayed in different sizes by using the display modes of the image sparkline function.


image


The image sparkline function has the following arguments where only 'source' is the required argument:

Argument

Description

source

The URL path, using an "https" protocol, of the image file.

[alt_text]

Alternative text that describes the image for accessibility.

Note that this argument supports the cell filter and find features of the cell.

[sizing]

Specifies the image dimensions as follows:

0 - Keep the aspect ratio to fit the cell.

1 - Stretch the image to cover the entire cell.

2 - Maintain the original image size, even if it exceeds the cell boundary.

3 - Customize the image size by using the height and width arguments.

The default value is 0.

[height]

The custom height of the image in pixels.

[width]

The custom width of the image in pixels.

[clipX]

The x-axis coordinate of the top left corner of the sub-rectangle of the source image to draw into the destination context.

The default value is 0.

[clipY]

The y-axis coordinate of the top left corner of the sub-rectangle of the source image to draw into the destination context.

The default value is 0.

[clipHeight]

The height of the sub-rectangle of the source image to draw into the destination context.

The default value is the height of the image.

[clipWidth]

The width of the sub-rectangle of the source image to draw into the destination context.

The default value is the width of the image.

[vAlign]

Vertical alignment of the image.

0 - Top

1 - Center

2 - Bottom

The default value is 2 (Bottom).

[hAlign]

Horizontal alignment of the image.

0 - Left

1 - Center

2 - Right

The default value is 0 (Left).

The image sparkline formula has the following syntax:

=IMAGE(source, [alt_text], [sizing], [height], [width], [clipX], [clipY], [clipHeight], [clipWidth], [vAlign], [hAlign])

Notes:

  • The source of the image can be a URL or a base64 string.

  • SpreadJS supports the import and export of image functions from Excel. However, import/export will be disabled if the image source is base64.

  • While exporting to Excel, some parameters, such as ([clipX], [clipY], [clipHeight], [clipWidth], [vAlign], and [hAlign], will be discarded.

Use Case Scenario

In the following use case, a list of 10 countries with the largest population in the world, is displayed. The list also displays the images for country flags which are picked through a web URL by using the IMAGE sparkline function.



// initializing Spread
spread = new GC.Spread.Sheets.Workbook(document.getElementById('ss'), { sheetCount: 1 });
spread.suspendPaint();

// set data array

// set value in cells
sheet1.setValue(1, 0, "Flag", GC.Spread.Sheets.SheetArea.dataArea);
sheet1.setValue(0, 0, "Top 10 Populated Countries", GC.Spread.Sheets.SheetArea.dataArea);
// set alignment of header row
sheet1.getRange(-1, 0, -1, 10).hAlign(GC.Spread.Sheets.HorizontalAlign.center);
sheet1.addSpan(0, 0, 1, 5, GC.Spread.Sheets.SheetArea.dataArea);
// add table to sheet1
sheet1.tables.add('tablePopulation', 1, 0, 11, 5);
