MBS( "GMImage.GetAttributesJSON"; ImageRef ) More
Parameters
| Parameter | Description | Example |
|---|---|---|
| ImageRef | The image reference number. | 1 |
Result
Returns JSON object or error.
Description
Queries all attributes as JSON.Only attributes created before are visible, so e.g. EXIF data may not yet be loaded and parsed.
e.g. for a PNG this may include the original color type and the bit depth:
{
| "png:IHDR.color-type-orig": | "4", |
| "png:IHDR.bit-depth-orig": | "16" |
For macOS and iOS, also see CGImageSource functions to read metadata like EXIF and IPTC. And also check MetaDataQuery.AttributesForFile function to get generic metadata.
Examples
Show attributes:
Set Variable [ $ImageRef ; Value: MBS("GMImage.NewFromFile"; "/Users/cs/Desktop/image2.png") ]
Show Custom Dialog [ "Attributes" ; MBS( "GMImage.GetAttributesJSON"; $ImageRef ) ]
Set Variable [ $r ; Value: MBS("GMImage.Release"; $ImageRef) ]
