static CreateImage(w, h) → {GdiBitmap}

js/foo_spider_monkey_panel.js, line 804

Parameters:

Name	Type	Description
w	number
h	number

Returns:

GdiBitmap

static Font(name, size_px, styleopt) → nullable {GdiFont}

js/foo_spider_monkey_panel.js, line 817

Performance note: avoid using inside `on_paint`.
Performance note II: try caching and reusing `GdiFont` objects, since the maximum amount of such objects is hard-limited by Windows. `GdiFont` creation will fail after reaching this limit.

Parameters:

Name	Type	Attributes	Default	Description
name	string
size_px	number			See Helper.js > Point2Pixel function for conversions
style	number	<optional>	0	See Flags.js > FontStyle

Returns:

GdiFont - null, if font is not present.

static Image(path) → nullable {GdiBitmap}

js/foo_spider_monkey_panel.js, line 831

Load image from file.

Performance note: consider using gdi.LoadImageAsync or gdi.LoadImageAsyncV2 if there are a lot of images to load or if the image is big.

Parameters:

Name	Type	Description
path	string

Returns:

GdiBitmap - null, if image failed to load.

Example

let img = gdi.Image('e:\\images folder\\my_image.png');

static LoadImageAsync(window_id, path) → {number}

js/foo_spider_monkey_panel.js, line 843

Load image from file asynchronously.

Parameters:

Name	Type	Description
window_id	number	unused
path	string

Returns:

number - a unique id, which is used in on_load_image_done.

Example

// See `samples/basic/LoadImageAsync.js`

static LoadImageAsyncV2(window_id, path) → {Promise.<?GdiBitmap>}

js/foo_spider_monkey_panel.js, line 856

Load image from file asynchronously. Returns a `Promise` object, which will be resolved when image loading is done.

Parameters:

Name	Type	Description
window_id	number	unused
path	string

Returns:

Promise.<?GdiBitmap>

Example

// See `samples/basic/LoadImageAsyncV2.js`
