Function Details

[hide private]

async_events_fd_get(...)

Retrive the file descriptor used to poll for asynchronous events.

If this is >= 0 it represents the file descriptor to poll in your main loop. When there is something to read you should call async_events_process().

Returns:: -1 on failure or the file descriptor on success (>= 0).

Note: ecore.evas already does this for you, you just need this if you are not using ecore.evas.

async_events_process(...)

Process pending asynchronous events.

You should monitor the file descriptor returned by async_events_fd_get() and call this function when there is something to read.

Returns:: number of processed events.

color_argb_premul(...)

Convert color to pre-multiplied format.

Returns: tuple of int: pre-multiplied (r, g, b, a)

Note: Evas works with pre-multiplied colors internally, so every color that comes from or goes to it must be in this format.

color_argb_unpremul(...)

Convert color to regular (no pre-multiplied) format.

Returns: tuple of int: (r, g, b, a)

Note: Evas works with pre-multiplied colors internally, so every color that comes from or goes to it must be in this format.

color_hsv_to_rgb(...)

Convert color from HSV to RGB format.

Returns: tuple of int: (r, g, b)

color_parse(...)

Converts a color description to (r, g, b, a) in pre-multiply form.

is_premul default value will depend on desc type:

desc is string: is_premul=False
desc is integer: is_premul=False
desc is tuple: is_premul=True

Returns: tuple of int: (r, g, b, a) in pre-multiply form.

color_rgb_to_hsv(...)

Convert color from RGB to HSV format.

Returns: tuple of int: (h, s, v)
