I want to use const dataImage = await imaging.encodeImageData(options); for a PNG
This works really well for getting from a layer, a base64 image, that can be used easily later and displayed in an <img>.
Unfortunately it seems there is no documented way to get a PNG.
But it seems it’s actually limited to JPEG, this is a big surprise to me, see:
Photoshop’s imaging types source code:
/**
* This API is exposed to allow image data to be used with UXP image elements. With the current version of UXP
* you must use jpeg/base64 encoding when assigning to an image element.
*
* ```javascript
* const dataImage = await imaging.encodeImageData(options);
* ```
*
* Example:
* ```javascript
* const imageElement = document.createElement('img');
*
* const jpegData = await imaging.encodeImageData({"imageData": imgObj.imageData, "base64": true});
*
* const dataUrl = "data:image/jpeg;base64," + jpegData;
* imageElement.src = dataUrl;
* document.body.appendChild(imageElement);
* ```
*
* @minVersion 24.4
* @async
*/
function encodeImageData(options: EncodeImageDataOptions): Promise<number[] | string>;
Does someone has an idea to get a PNG out of this array from getData()?
const imageObj = await psImg.getPixels({
layerID: 1,
})
const pixelData = await imageObj.imageData.getData({})
Types
/**
* Return pixel information from an `PhotoshopImageData` instance as a typed array.
* The return type depends on the `componentSize` of the image.
*
* | Component Size | Return type |
* | -------------- | ----------- |
* | 8 | Uint8Array |
* | 16 | Uint16Array |
* | 32 | Float32Array |
*
* Example:
* ```javascript
* const pixelData = await imageObj.imageData.getData()
* ```
* @param options
*/
getData: (options: GetDataOptions) => Promise<Uint8Array | Uint16Array | Float32Array>;
