Public Attributes | |
bool | fSuppressPrints = false |
int | fMaxTextureSizeOverride = SK_MaxS32 |
Overrides: These options override feature detection using backend API queries. More... | |
int | fMaxTileSizeOverride = 0 |
If non-zero, overrides the maximum size of a tile for sw-backed images and bitmaps rendered by SkGpuDevice. More... | |
bool | fSuppressDualSourceBlending = false |
int | fBufferMapThreshold = -1 |
the threshold in bytes above which we will use a buffer mapping API to map vertex and index buffers to CPU memory in order to update them. More... | |
bool | fUseDrawInsteadOfPartialRenderTargetWrite = false |
some gpus have problems with partial writes of the rendertarget | |
bool | fUseShaderSwizzling = false |
Force us to do all swizzling manually in the shader and don't rely on extensions to do swizzling. More... | |
bool | fDoManualMipmapping = false |
Construct mipmaps manually, via repeated downsampling draw-calls. More... | |
bool | fEnableInstancedRendering = false |
Enable instanced rendering as long as all required functionality is supported by the HW. More... | |
bool | fAllowPathMaskCaching = false |
If true this allows path mask textures to be cached. More... | |
bool | fRequireDecodeDisableForSRGB = true |
If true, sRGB support will not be enabled unless sRGB decoding can be disabled (via an extension). More... | |
bool | fDisableGpuYUVConversion = false |
If true, the GPU will not be used to perform YUV -> RGB conversion when generating textures from codec-backed images. | |
bool | fSuppressPathRendering = false |
If true, the caps will never report driver support for path rendering. | |
bool | fWireframeMode = false |
Render everything in wireframe. | |
GpuPathRenderers | fGpuPathRenderers = GpuPathRenderers::kAll |
float | fGlyphCacheTextureMaximumBytes = 2048 * 1024 * 4 |
The maximum size of cache textures used for Skia's Glyph cache. | |
bool | fAvoidStencilBuffers = false |
Bugs on certain drivers cause stencil buffers to leak. More... | |
bool GrContextOptions::fAllowPathMaskCaching = false |
If true this allows path mask textures to be cached.
This is only really useful if paths are commonly rendered at the same scale and fractional translation.
bool GrContextOptions::fAvoidStencilBuffers = false |
Bugs on certain drivers cause stencil buffers to leak.
This flag causes Skia to avoid allocating stencil buffers and use alternate rasterization paths, avoiding the leak.
int GrContextOptions::fBufferMapThreshold = -1 |
the threshold in bytes above which we will use a buffer mapping API to map vertex and index buffers to CPU memory in order to update them.
A value of -1 means the GrContext should deduce the optimal value for this platform.
bool GrContextOptions::fDoManualMipmapping = false |
Construct mipmaps manually, via repeated downsampling draw-calls.
This is used when the driver's implementation (glGenerateMipmap) contains bugs. This requires mipmap level and LOD control (ie desktop or ES3).
bool GrContextOptions::fEnableInstancedRendering = false |
Enable instanced rendering as long as all required functionality is supported by the HW.
Instanced rendering is still experimental at this point and disabled by default.
int GrContextOptions::fMaxTextureSizeOverride = SK_MaxS32 |
Overrides: These options override feature detection using backend API queries.
These overrides can only reduce the feature set or limits, never increase them beyond the detected values.
int GrContextOptions::fMaxTileSizeOverride = 0 |
If non-zero, overrides the maximum size of a tile for sw-backed images and bitmaps rendered by SkGpuDevice.
bool GrContextOptions::fRequireDecodeDisableForSRGB = true |
If true, sRGB support will not be enabled unless sRGB decoding can be disabled (via an extension).
If mixed use of "legacy" mode and sRGB/color-correct mode is not required, this can be set to false, which will significantly expand the number of devices that qualify for sRGB support.
bool GrContextOptions::fUseShaderSwizzling = false |
Force us to do all swizzling manually in the shader and don't rely on extensions to do swizzling.
