<return type="Image" />
|
|
<description>
|
|
Returns an image of the same size as the bitmap and with a [enum Image.Format] of type [code]FORMAT_L8[/code]. [code]true[/code] bits of the bitmap are being converted into white pixels, and [code]false[/code] bits into black.

<description>
|
|
Creates a bitmap with the specified size, filled with [code]false[/code].

|
|
<description>
|
|
Creates a bitmap that matches the given image dimensions, every element of the bitmap is set to [code]false[/code] if the alpha value of the image at that position is equal to [code]threshold[/code] or less, and [code]true[/code] in other case.

|
|
<description>
|
|
Applies morphological dilation or erosion to the bitmap. If [code]pixels[/code] is positive, dilation is applied to the bitmap. If [code]pixels[/code] is negative, erosion is applied to the bitmap. [code]rect[/code] defines the area where the morphological operation is applied. Pixels located outside the [code]rect[/code] are unaffected by [method grow_mask].
