bool eo_cxx::efl::file::save ( std::string  file_, ::efl::eina::optional< std::string >  key_, ::efl::eina::optional< std::string >  flags_  ) const

inline

Save the given image object's contents to an (image) file.

The extension suffix on file will determine which saver module Evas is to use when saving, thus the final file's format. If the file supports multiple data stored in it (Eet ones), you can specify the key to be used as the index of the image in it.

You can specify some flags when saving the image. Currently acceptable flags are quality and compress. Eg.: "quality=100 compress=9"

Parameters

file	The filename to be used to save the image (extension obligatory).
key	The image key in the file (if an Eet one), or NULL, otherwise.
flags	String containing the flags to be used (NULL for none).

void eo_cxx::efl::file::eject ( ) const

inline

Eject the represented object.

Get rid of and clean the pointed resource.

void eo_cxx::efl::file::file_get ( const char **  file_, const char **  key_  ) const

inline

Retrieve the source file from where an image object is to fetch the real image data (it may be an Eet file, besides pure image ones).

You must not modify the strings on the returned pointers.

Note

Use NULL pointers on the file components you're not interested in: they'll be ignored by the function.

Parameters

file	The image file path.
key	The image key in file (if its an Eet one), or NULL, otherwise.

bool eo_cxx::efl::file::file_set ( ::efl::eina::optional< std::string >  file_, ::efl::eina::optional< std::string >  key_  ) const

inline

Set the source file from where an image object must fetch the real image data (it may be an Eet file, besides pure image ones).

If the file supports multiple data stored in it (as Eet files do), you can specify the key to be used as the index of the image in this file.

Example:

img = evas_object_image_add(canvas);
evas_object_image_file_set(img, "/path/to/img", NULL);
err = evas_object_image_load_error_get(img);
if (err != EVAS_LOAD_ERROR_NONE)
{
fprintf(stderr, "could not load image '%s'. error string is \"%s\"\n",
valid_path, evas_load_error_str(err));
}
else
{
evas_object_image_fill_set(img, 0, 0, w, h);
evas_object_resize(img, w, h);
evas_object_show(img);
}

Parameters

file	The image file path.
key	The image key in file (if its an Eet one), or NULL, otherwise.
