| -Version
|

|
| - Last Modifed Date: April 9, 2012
|

|
| -Dependencies
|
| -
|
| - OpenGL ES 2.0 is required.
|

|
| -Overview
|
| -
|
| - This extension adds the ability to vertically flip texture image data when
|
| - calling TexImage2D and TexSubImage2D.
|
| -
|
| -Issues
|
| -
|
| -
|
| -New Tokens
|
| -
|
| - Accepted by the <param> parameter of PixelStorei:
|
| -
|
| - UNPACK_FLIP_Y_CHROMIUM 0x9240
|
| -
|
| -Additions to the OpenGL ES 2.0 Specification
|
| -
|
| - Modifications to Table 3.1 (PixelStore Parameters)
|
| -
|
| - Add the following entry:
|
| -
|
| - Parameter Name Type Initial Value Valid Range
|
| - ============== ==== ============= ===========
|
| - UNPACK_FLIP_Y_CHROMIUM boolean FALSE {TRUE, FALSE}
|
| -
|
| - Modifications to 3.6.2 Transfer of Pixel Rectangles, in the Unpacking
|
| - section:
|
| -
|
| - Change
|
| - "If p indicates the location in memory of the first element of the first
|
| - row, then the first element of the Nth row is indicated by
|
| - p + Nk (3.9)"
|
| - to
|
| - "If p indicates the location in memory of the first element of the first
|
| - row, then the first element of the Nth row is indicated by
|
| - p + Nk (3.9)
|
| - if UNPACK_FLIP_Y is FALSE. Otherwise, the first element of the Nth row
|
| - is indicated by
|
| - p - Nk (3.10)
|
| -
|
| - After the sentence
|
| -
|
| - "If the number of bits per element is not 1, 2, 4, or 8 times the number
|
| - of bits in a GL ubyte, then k = nl for all values of a."
|
| -
|
| - insert:
|
| -
|
| - "If UNPACK_FLIP_Y_CHROMIUM is FALSE then p is equal to pixels. Otherwise
|
| - p is pixels + (height - 1)k."
|
| -
|
| -Interactions with GL_EXT_unpack_subimage
|
| -
|
| - Do not add the sentence "If UNPACK_FLIP_Y_CHROMIUM is FALSE ..." described
|
| - in this extension. Instead do the following after applying
|
| - GL_EXT_unpack_subimage:
|
| -
|
| - Change
|
| -
|
| - "There is a mechanism for selecting a sub-rectangle of groups
|
| - from a larger containing rectangle. This mechanism relies on
|
| - three integer parameters: UNPACK_ROW_LENGTH, UNPACK_SKIP_ROWS,
|
| - and UNPACK_SKIP_PIXELS. Before obtaining the first group from
|
| - memory, the pointer supplied to TexImage2D is effectively
|
| - advanced by (UNPACK_SKIP_PIXELS)n + (UNPACK_SKIP_ROWS)k
|
| - elements. Then <width> groups are obtained from contiguous
|
| - elements in memory (without advancing the pointer), after
|
| - which the pointer is advanced by k elements. <height> sets of
|
| - <width> groups of values are obtained this way. See figure
|
| - 3.6."
