ControllerImage_GetSVGForAxis

Get the raw SVG data for one axis on a controller.

Header File

Syntax

const char * ControllerImage_GetSVGForAxis(ControllerImage_Device *device, SDL_GamepadAxis axis);

Function Parameters

ControllerImage_Device *	device	the device object for which to obtain SVG data.
SDL_GamepadAxis	axis	the axis on the device for which to obtain SVG data.

Return Value

(const char *) Returns the raw SVG data for the image on success, or NULL on error; call SDL_GetError() for details.

Remarks

This can be used if the caller intends to render its own images from SVG-format data. Most apps will use ControllerImage_CreateSurfaceForAxis(), instead, which will handle generating the pixels internally.

This returns NULL on error, but also if there is no artwork available. For a controller missing a button, this is not necessarily an error. If the distinction is important, consider calling ControllerImage_DeviceHasArtworkForButton().

The returned string (SVG files are text-based XML files) is owned by ControllerImage, not the caller, and should not be free'd. The pointer remains valid until device is destroyed.

Thread Safety

This function is not thread safe.
