/**
|
|
* @defgroup Evas_Object_Image Image Object Functions
|
|
*
|
|
* Functions used to create and manipulate image objects.
|
|
*
|
|
* Note - Image objects may return or accept "image data" in multiple formats.
|
|
* This is based on the colorspace of an object. Here is a rundown on formats:
|
|
*
|
|
* EVAS_COLORSPACE_ARGB8888:
|
|
*
|
|
* This pixel format is a linear block of pixels, starting at the top-left row
|
|
* by row until the bottom right of the image or pixel region. All pixels are
|
|
* 32-bit unsigned int's with the high-byte being alpha and the low byte being
|
|
* blue in the format ARGB. Alpha may or may not be used by evas depending on
|
|
* the alpha flag of the image, but if not used, should be set to 0xff anyway.
|
|
*
|
|
* This colorspace uses premultiplied alpha. That means that R, G and B cannot
|
|
* exceed A in value. The conversion from non-premultiplied colorspace is:
|
|
*
|
|
* R = (r * a) / 255; G = (g * a) / 255; B = (b * a) / 255;
|
|
*
|
|
* So 50% transparent blue will be: 0x80000080. This will not be "dark" - just
|
|
* 50% transparent. Values are 0 == black, 255 == solid or full red, green or
|
|
* blue.
|
|
*
|
|
* EVAS_COLORSPACE_YCBCR422P601_PL:
|
|
*
|
|
* This is a pointer-list indirected set of YUV (YCbCr) pixel data. This means
|
|
* that the data returned or set is not actual pixel data, but pointers TO
|
|
* lines of pixel data. The list of pointers will first be N rows of pointers
|
|
* to the Y plane - pointing to the first pixel at the start of each row in
|
|
* the Y plane. N is the height of the image data in pixels. Each pixel in the
|
|
* Y, U and V planes is 1 byte exactly, packed. The next N / 2 pointers will
|
|
* point to rows in the U plane, and the next N / 2 pointers will point to
|
|
* the V plane rows. U and V planes are half the horizontal and vertical
|
|
* resolution of the U plane.
|
|
*
|
|
* Row order is top to bottom and row pixels are stored left to right.
|
|
*
|
|
* There is a limitation that these images MUST be a multiple of 2 pixels in
|
|
* size horizontally or vertically. This is due to the U and V planes being
|
|
* half resolution. Also note that this assumes the itu601 YUV colorspace
|
|
* specification. This is defined for standard television and mpeg streams.
|
|
* HDTV may use the itu709 specification.
|
|
*
|
|
* Values are 0 to 255, indicating full or no signal in that plane
|
|
* respectively.
|
|
*
|
|
* EVAS_COLORSPACE_YCBCR422P709_PL:
|
|
*
|
|
* Not implemented yet.
|
|
*
|
|
* EVAS_COLORSPACE_RGB565_A5P:
|
|
*
|
|
* In the process of being implemented in 1 engine only. This may change.
|
|
*
|
|
* This is a pointer to image data for 16-bit half-word pixel data in 16bpp
|
|
* RGB 565 format (5 bits red, 6 bits green, 5 bits blue), with the high-byte
|
|
* containing red and the low byte containing blue, per pixel. This data is
|
|
* packed row by row from the top-left to the bottom right.
|
|
*
|
|
* If the image has an alpha channel enabled there will be an extra alpha plane
|
|
* after the color pixel plane. If not, then this data will not exist and
|
|
* should not be accessed in any way. This plane is a set of pixels with 1
|
|
* byte per pixel defining the alpha values of all pixels in the image from
|
|
* the top-left to the bottom right of the image, row by row. Even though
|
|
* the values of the alpha pixels can be 0 to 255, only values 0 through to 32
|
|
* are used, 32 being solid and 0 being transparent.
|
|
*
|
|
* RGB values can be 0 to 31 for red and blue and 0 to 63 for green, with 0
|
|
* being black and 31 or 63 being full red, green or blue respectively. This
|
|
* colorspace is also pre-multiplied like EVAS_COLORSPACE_ARGB8888 so:
|
|
*
|
|
* R = (r * a) / 32; G = (g * a) / 32; B = (b * a) / 32;
