* DESCRIPTION |
|
95 |
* mlib_ImageCreateStruct() creates a mediaLib image data structure |
|
96 |
* using parameter supplied by user. |
|
97 |
* |
|
98 |
* mlib_ImageCreate() creates a mediaLib image data structure and |
|
99 |
* allocates memory space for image data. |
|
100 |
* |
|
101 |
* mlib_ImageDelete() deletes the mediaLib image data structure |
|
102 |
* and frees the memory space of the image data if it is allocated |
|
103 |
* through mlib_ImageCreate(). |
|
104 |
* |
|
105 |
* mlib_ImageCreateSubimage() creates a mediaLib image structure |
|
106 |
* for a sub-image based on a source image. |
|
107 |
* |
|
108 |
* mlib_ImageCreateRowTable() creates row starts pointer table and |
|
109 |
* puts it into mlib_image->state field. |
|
110 |
* |
|
111 |
* mlib_ImageDeleteRowTable() deletes row starts pointer table from |
|
112 |
* image and puts NULL into mlib_image->state field. |
|
113 |
* |
|
114 |
* mlib_ImageSetPaddings() sets new values for the clipping box paddings |
|
115 |
* |
|
116 |
* mlib_ImageSetFormat() sets new value for the image format |
