| | | | | | | | | | | | | | | | | | _mesa_unpack_bitmap() was introduced by commit 02b801c to handle the case when data is stored in PBO by display lists, in the context of this bug: Incorrect pixels read back if draw bitmap texture through Display list https://bugs.freedesktop.org/show_bug.cgi?id=10370 Since _mesa_unpack_image() already handles the case of GL_BITMAP, this patch removes _mesa_unpack_bitmap() and makes affected calls go through _mesa_unapck_image() instead. The sample test attached to the original bug report passes with this change and there are no piglit regressions.

* mesa: Add helpers to extract GL_COLOR_INDEX to RGBA float/ubyteIago Toral Quiroga2015-01-122-0/+99
| | | | | | | | | | | | | | | | | | | | | We only use _mesa_make_temp_ubyte_image in texstore.c to convert GL_COLOR_INDEX to RGBA, but this helper does more stuff than this. All uses of this helper can be replaced with calls to _mesa_format_convert except for this GL_COLOR_INDEX conversion. This patch extracts the GL_COLOR_INDEX to RGBA logic to a separate helper so we can use that instead from texstore.c. In future patches we will replace all remaining calls to _mesa_make_temp_ubyte_image in the repository (related to compressed formats) with calls to _mesa_format_convert so we can remove _mesa_make_temp_ubyte_image and related functions. v2: - Remove ‘for’ loop initial declaration.

* mesa: Add RGBA to Luminance conversion helpersIago Toral Quiroga2015-01-122-0/+224
| | | | | | | | | | | | | | | | | | For glReadPixels with a Luminance destination format we compute luminance values from RGBA as L=R+G+B. This, however, requires ad-hoc implementation, since pack/unpack functions or _mesa_swizzle_and_convert won't do this (and thus, neither will _mesa_format_convert). This patch adds helpers to do this computation so they can be used to support conversion to luminance formats. The current implementation of glReadPixels does this computation as part of the span functions in pack.c (see _mesa_pack_rgba_span_float), that do this together with other things like type conversion, etc. We do not want to use these functions but use _mesa_format_convert instead (later patches will remove the color span functions), so we need to extract this functionality as helpers.

| | | | | | | | | | | | | | | | | We have _mesa_swap{2,4} but these do in-place byte-swapping only. The new functions receive an extra parameter so we can swap bytes on a source input array and store the results in a (possibly different) destination array. This is useful to implement byte-swapping in pixel uploads, since in this case we need to swap bytes on the src data which is owned by the application so we can't do an in-place byte swap. v2: - Include compiler.h in image.h, which is necessary to build in MSCV as indicated by Brian Paul.

* mesa: Add a rebase_swizzle parameter to _mesa_format_convertIago Toral Quiroga2015-01-122-70/+171
| | | | | | | | | | | | | | | | | | | | | The new parameter allows callers to provide a rebase swizzle that the function needs to use to match the requirements of the base internal format involved. This is necessary when the source or destination internal formats (depending on whether we are doing the conversion for a pixel download or a pixel upload respectively) do not match the base formats of the source or destination formats of the conversion. This can happen when the driver does not support the internal formats and uses a different format to store pixel data internally. For example, a texture upload from RGB to Luminance in a driver that does not support textures with a Luminance format may decide to store the Luminance data as RGBA. In this case we want to store the RGBA values as (R,R,R,1). Following the same example, when we download from that texture to RGBA we want to read (R,0,0,1). The rebase_swizzle parameter allows these transforms to happen. Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v2 by Iago Toral <[email protected]>: - When testing if we can directly pack we should use the src format to check if we are packing from an RGBA format. The original code used the dst format for the ubyte case by mistake. - Fixed incorrect number of bits for dst, it was computed using the src format instead of the dst format. - If the dst format is an array format, check if it is signed. We were only checking this for the case where it was not an array format, but we need to know this in both scenarios. - Fixed incorrect swizzle transform for the cases where we convert between array formats. - Compute is_signed and bits only once and for the dst format. We were computing these for the src format too but they were overwritten by the dst values immediately after. - Be more careful when selecting the integer path. Specifically, check that both src and dst are integer types. Checking only one of them should suffice since OpenGL does not allow conversions between normalized and integer types, but putting extra care here makes sense and also makes the actual requirements for this path more clear. - The format argument for pack functions is the destination format we are packing to, not the source format (which has to be RGBA). - Expose RGBA8888_* to other files. These will come in handy when in need to test if a given array format is RGBA or in need to pass RGBA formats to mesa_format_convert. v3 by Samuel Iglesias <[email protected]>: - Add an RGBA8888_INT definition. v4 by Iago Toral <[email protected]> after review by Jason Ekstrand: - Added documentation for _mesa_format_convert. - Added additional explanatory comments for integer conversions. - Ensure that we use _messa_swizzle_and_convert for all signed source formats. - Squashed: do not directly (un)pack to RGBA UINT if the source is not unsigned. v5 by Iago Toral <[email protected]>: - Adapted to the new implementation of mesa_array_format as a plain uint32_t bitfield.

| | | | | | | | | | | | | | | | | | | | | | If we need the base format for a mesa_array_format we have to find the matching mesa_format first. This is expensive because it requires to loop through all existing mesa formats until we find the right match. We can resolve the base format of an array format directly by looking at its swizzle information. Also, we can have _mesa_get_format_base_format accept an uint32_t which can pack either a mesa_format or a mesa_array_format and resolve the base format for either type. This way clients do not need to check if they have a mesa_format or a mesa_array_format and call different functions depending on the case. Another reason to resolve the base format for array formats directly is that we don't have matching mesa_format enums for every possible array format, so for some GL format/type combinations we can produce array formats that don't have a corresponding mesa format, in which case we would not be able to find the base format. Example format=GL_RGB, type=GL_UNSIGNED_SHORT. This type would map to something like MESA_FORMAT_RGB_UNORM16, but we don't have that. Reviewed-by: Jason Ekstrand <[email protected]>
