Methods
-
ApplyAlpha(alpha) → {GdiBitmap}
-
Parameters:
Name Type Description alpha
number Valid values 0-255. Returns:
GdiBitmap -
ApplyMask(img)
-
Changes will be saved in the current bitmap.
Parameters:
Name Type Description img
GdiBitmap Example
<caption>Blur image<caption> // See `samples/basic/Apply Mask.js`
-
Clone(x, y, w, h) → {GdiBitmap}
-
Parameters:
Name Type Description x
number y
number w
number h
number Returns:
GdiBitmap -
CreateRawBitmap() → {GdiRawBitmap}
-
Create a DDB bitmap from GdiBitmap, which is used in GdiGraphics#GdiDrawBitmap
Returns:
GdiRawBitmap -
GetColourScheme(max_count) → {Array.<number>}
-
Parameters:
Name Type Description max_count
number Returns:
Array.<number> -
GetColourSchemeJSON(max_count) → {string}
-
Returns a JSON array in string form so you need to use JSON.parse() on the result.
Each entry in the array is an object which contains colour and frequency values.
Uses a different method for calculating colours than GdiBitmap#GetColourScheme.
Image is automatically resized during processing for performance reasons so there's no need to resize before calling the method.Parameters:
Name Type Description max_count
number Returns:
stringExample
// See docs\Helpers.js for "toRGB" function. img = ... // use utils.GetAlbumArtV2 / gdi.Image / etc colours = JSON.parse(img.GetColourSchemeJSON(5)); console.log(colours[0].col); // -4194304 console.log(colours[0].freq); // 0.34 console.log(toRGB(colours[0].col)); // [192, 0, 0]
-
GetGraphics() → {GdiGraphics}
-
Note: don't forget to use GdiBitmap#ReleaseGraphics after work on GdiGraphics is done!
Returns:
GdiGraphics -
InvertColours() → {GdiBitmap}
-
Inverts the colours in a bitmap, to create a negative image. i.e. White becomes black, black becomes white, etc.
Returns:
GdiBitmap -
ReleaseGraphics(gr)
-
Parameters:
Name Type Description gr
