This function creates a “blank” Media object of the speciﬁed dimensions and fully supports
the CMYK color-space.

Syntax

makeCanvas(

[Xs @ <width in pixels>]

[Ys @ <height in pixels>]

[Rtype @ <bit-depth>]

[FillColor @ <color in hexadecimal or rgb>]

[Transparency @ <true, false>]

Parameters

and

- specify the width and height of the canvas in pixels. If Xs or Ys is not speciﬁed,

a 1x1 canvas is created. If only one of Xs and Ys is speciﬁed, the unspeciﬁed parameter is
assumed to be the same as the speciﬁed one (a square canvas is created).

Rtype

- speciﬁes the bit-depth. Supported bit-depths are: “RGB-24”, “RGBA-32”, “CMYK-

32”, “CMYKA-40”, “Gray-8”, “RGB-15”, “RGB-16”, “RGBA-16”, “RGB-18”, “Alpha-8”,
“HLS-24”, and “HSV-24”. The default bit-depth is “RGBA-32” (RGB, 32-bit).

NOTE:

The 16-bit type, is 5-6-5, while the 16a-bit is 1-5-5-5 with the top bit as an alpha channel.

FillColor

- determines the color value given to each pixel in the generated canvas. If

FillColor is not speciﬁed, each pixel is set to black.

Transparency

- set to “true”, the canvas’ pixels are all set as transparent and FillColor is

used as both the foreground and background color. If Transparency is set to false, the
canvas’ pixels are set as solid. FillColor is used for the foreground color, and the
background color is black. Transparency is set to false by default.

Example

var image = new Media();

var text = new Media();

image.makeCanvas(Xs @ 200, Ys @ 150, FillColor @ 0x0000ff);

text.makeText(text @ "hello world", font @ "Arial", style @ "Bold",
size @ 24, smooth @ true, color @ 0xffffff);

image.composite(source @ text);

image.save(type @ "jpeg");
