* Allow toString capability to be toggled independent of developer mode.Gravatar commit-bot@chromium.org2014-03-13
| | | | | | | | | | | | This change is motivated by the desire to see the text information in the debugger when not in developer mode. It is structured so user's can disable it if the capability is not wanted. R=bsalomon@google.com Author: robertphillips@google.com Review URL: https://codereview.chromium.org/197763008 git-svn-id: http://skia.googlecode.com/svn/trunk@13795 2bbb7eff-a529-9590-31e7-b0007b416f81
* Add a class to allocate small objects w/o extra calls to new.Gravatar commit-bot@chromium.org2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add SkSmallAllocator, a template for allocating small (as defined by the instantiation) objects without extra calls to new. Add a helper macro to make using it simple. Remove SkTemplatesPriv.h, whose behavior is replaced by SkSmallAllocator. The old SK_PLACEMENT_NEW had the following drawbacks: - Easily confused with SkNEW_PLACEMENT. - Requires passing around lots of void*s along with the storageSize. - Requires using a separate class for deleting it. - We had multiple ways Auto objects for deleting in different places. - It always did a straight heap allocation on Windows, meaning Windows did not get any advantages from the confusing code. The new SkSmallAllocator simplifies things: - It is clear about what it does. - It takes care of the deletion in one place that is automatically handled. Further, the new class can be used to create more than one object. This is in preparation for BUG=skia:1976, for which we would like to create a new object without extra heap allocations. The plan is to create both the blitter and the new object on the stack using the SkSmallAllocator. Add a new test for SkSmallAllocator. SkShader.h: Move the private version of CreateBitmapShader to SkBitmapProcShader (which already has the implementation) and remove the friend class (which was only used to call this private function). This allows SkSmallAllocator to reside in the private src/ directory. SkBitmapProcShader: Move CreateBitmapShader and the macro for the storage size here. With the macro in a (private) header, the (private) headers with function declarations (which now depend on the storage size used) can see the macro. Use SkSmallAllocator in CreateBitmapShader. Change the macro to kBlitterStorageByteCount, since SkSmallAllocator takes a byte count as its template parameter. SkBlitter: Use the SkSmallAllocator. Remove Sk3DShader::fKillProc and SkAutoCallProc. Both of their behaviors have been moved into SkSmallAllocator (SkAutoCallProc was unnecessary anyway, because the only time we ever used it we also called detach(), so its auto behavior never happened). Create the Sk3DShader on the stack, if there's room. Remove the helper version of Choose, which was unused. SmallAllocatorTest: Test for the new class. The rest: Use SkSmallAllocator.

* Refactor read and write buffers.Gravatar commit-bot@chromium.org2014-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer a step each in the hierarchy. What used to be this: SkFlattenableWriteBuffer -> SkOrderedWriteBuffer SkFlattenableReadBuffer -> SkOrderedReadBuffer SkFlattenableReadBuffer -> SkValidatingReadBuffer is now SkWriteBuffer SkReadBuffer -> SkValidatingReadBuffer Benefits: - code is simpler, names are less wordy - the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed - write buffers are completely devirtualized, important for record speed This refactoring was mostly mechanical. You aren't going to find anything interesting in files with less than 10 lines changed.

* Mutexes in pixelrefs were done very sloppily initially. The code (a) assumes allGravatar reed@google.com2012-05-17
| | | | | | | | | | | | | | | | | | | | pixelref subclasses want a mutex to guard their lock/unlock virtuals, and (b) most subclasses use the same mutex for *all* of their instances, even when there is no explicit need to guard modifying one instances with another. When we try drawing bitmaps from multiple threads, we are seeing a lot of slow- down from these mutexes. This CL has two changes to try to speed things up. 1. Add setPreLocked(), for pixelrefs who never need the onLockPixels virtual to be called. This speeds up those subclasses in multithreaded environs as it avoids the mutex lock all together (e.g. SkMallocPixelRef). 2. Add setMutex() to allow a subclass to change the mutex choice. ashmem wants this, since its unflattening constructor cannot pass down the null, it needs to cleanup afterwards.

Perform an unsigned shift during the calculation, so we don't get sign-extension bleed when packing the two values (X,Y) into our 32bit slot.

* call readyToDraw() instead of just checking for null pixels, since we couldGravatar reed@android.com2010-09-10
| | | | | | | | | have a bitmap with pixels, but no (required) colortable. readyToDraw() knows to check for this. git-svn-id: http://skia.googlecode.com/svn/trunk@599 2bbb7eff-a529-9590-31e7-b0007b416f81
* fix overflow in matrixproc, and add debugging code to test thatGravatar reed@android.com2010-04-14

* remove check for filtering. Now if the src is opaque, the filtered resultGravatar reed@android.com2009-10-26
| | | | | | | | always will be too. git-svn-id: http://skia.googlecode.com/svn/trunk@406 2bbb7eff-a529-9590-31e7-b0007b416f81
* don't force bitmapIsOpaque to false if we're instrinsically 16bitGravatar reed@android.com2009-10-14
| | | | | | | | This allows us to take more optimal paths, even when filtering or dithering git-svn-id: http://skia.googlecode.com/svn/trunk@386 2bbb7eff-a529-9590-31e7-b0007b416f81
* expand SkShader's flag kConstInY to 16 and 32 variants, allowing a shaderGravatar reed@android.com2009-08-27
| | | | | | | | | | | | (like gradients) to support predithering. If they do, then they would suppress kConstInY16, since they no longer are const. The blitters now check for each flag separately, so we don't have to give up const-in-Y in the 32bit case, since in that mode we don't care about dithering. git-svn-id: http://skia.googlecode.com/svn/trunk@339 2bbb7eff-a529-9590-31e7-b0007b416f81
* special case 1x1 bitmaps when drawn as a shader (treat as a solid color)Gravatar reed@android.com2009-08-25

* fixes around isOpaque and ditheringGravatar reed@android.com2009-08-22
| | | | | | | | | | | | | | - copyTo() now preserves isOpaqueness, and BitmapCopyTest tests it - bitmap shader doesn't claim to have shadespan16 if dithering is on, since its sampler doesn't auto-dither (note that gradients do auto-dither in their 16bit sampler) - blitter setup just relies on the shader to report if its 16bit sampler can be called (allowing gradients to say yes regardless of dither, but bitmaps to say no if dithering is on) git-svn-id: http://skia.googlecode.com/svn/trunk@331 2bbb7eff-a529-9590-31e7-b0007b416f81
* add method to compute max count for a given buffer size in the bitmap shader.Gravatar reed@android.com2009-08-14
