2022-01-12reduce explicit Skia flushingLuboš Luňák
The docs say that Skia handles this itself, and with Vulkan excessive flushing may show up in profiling in some cases, as it's apparently a non-trivial operation in GPU mode. Remove even the two workarounds, I cannot reproduce the problems anymore, so let's assume it's been fixed in Skia. But still keep the flushing after a certain number of operations, as too many pending operations still may overload Skia (or Vulkan?), besides tdf#136369 I can also reproduce it while loading bsc#1183308 which does a large number of tiny VirtualDevice's and does GetBitmap() on them. Also change the counter to be global, as we use just one Skia drawing context.

2021-12-10cache Skia drawing based on checksum of bitmap content (tdf#146095)Luboš Luňák
Previously the caching was based on SkImage's uniqueID(), which detects whether it's the same image. For caching to work based on this it is required that the underlying image does not change, which generally means using the same Bitmap(Ex) for repeated drawing. But e.g. in tdf#146096 canvas (AFAICT) tries to cache bitmaps by copying them around, which generates so many bitmaps that they all do not fit in the cache (helped by the fact that the edit window still animates them too, and bitmap caching in canvas being broken). It feels kinda lame and unnecessary to checksum pixels of many bitmaps to be drawn just to find out whether their drawing can be sped up, and it really should be fixed higher up wherever it's broken, but I've already failed several times trying to fix this in canvas, so let's just roll with this. This is done only for raster-based images, because GPU-backed drawing is fast enough to deal even with expensive drawing (and fetching GPU-backend pixels would be expensive). On my machine this changes showing the slide from not being able to quite keep up to about 20% CPU usage.

2021-12-07Re-Enable DrawTransformBitmapExDirect for render backendsArmin Le Grand (Allotropia)
Unfortunately the add/usage of HasFastDrawTransformedBitmap did disable the system-dependent implementations/fast-path for DrawTransformBitmapExDirect and it's implemenations, except for Skia. This means that the current backends for Windows/Mac/Cairo/headless/Qt5 have to do expensive pixel operations when a Bitmap is 'really' transformed (rotate/shear) since some time. The nine implementations using ::hasFastDrawTransformedBitmap (grep for it) all return false, except the Skia one. Since HasFastDrawTransformedBitmap() uses that and itself is used in the very central mehod OutputDevice::DrawTransformedBitmapEx(...) to decide if that fast-path shall/can be used at all, it was *no longer used* - except for Skia - what makes Skia definitely performing better with transformed Bitmaps, or the other way around - the others worse. HasFastDrawTransformedBitmap() is used in only two places, the second is in the canvas helper to decide if to try to use that fast-path for presentation rendering. A method at OutputDevice to see if that fast-path is implemented is therefore currently needed, but for the canvas helper only. Since this will/should be converted to primitive usage (hopefully) anyways, nine impementations calling these virtual functions often and the danger to produce a mismatch/ error beween implementations of hasFastDrawTransformedBitmap and drawTransformedBitmap (as happened here, but can also happen when someone adds or removes an implementation) I looked for a way to solve that differenly and more safe. Since SalGraphics::DrawTransformedBitmap anyways returns a bool to signal it's success I take this as base to implement a buffered test directly at SalGraphics, also directly set a local flag to detect that functionality if DrawTransformedBitmap is used anyways before the test is/would be needed. Combined wih that small test to check only if this was not yet used and thus tested by DrawTransformedBitmap anyways I can offer a reliable non-virtual method at OutputDevice called ImplementsFastDrawTransformedBitmap() that will be used at the single necessary location - in the canvas helper. Since that small test direcly uses one of the nine implementations of hasFastDrawTransformedBitmap it is fundamenally more reliable and probably the copy bitmap/writeBack never really used (I tested that it works) due to an earlier use of DrawTransformedBitmap did the check potentially already. I also took a look at the cairo version (since I had this one running here) and ensured that the buffering of the system-dependent form of the Bitmap as cairo surface still works. Regarding the newly introduced fAlpha parameter I want to add some remarks: - It should be called fOpacity to make clear that it describes opacity, defining that if 1.0 == fAlpha means *no* transparency. That word is used in other graphic systems and makes more clear what function it has. It is the opposite of transparency, but works the same. - Currently all implementations of ::drawTransformedBitmap - except Skia where it was implemented - do not use it, but return false. It will in most cases not be too complicated to add/implement it, e.g. for cairo anyways a transparency surface will/is created, fAlpha can just be merged in, and the criteria for buffering that may be extended to remember for which value (if at all) of fAlpha that was prepared. I strongly recommend implementing these for our main graphic backends. - The primitive renderer uses another more general way to add an extra alpha channel to paint when needed - it draws the content (any content) that needs to be transparent to a buffer and then that buffer using the intended transparency. This is discussable since may be more expensive, but more general and keeps the interface less complex. We can see here that adding that complexity to the existing interface at OutputDevice makes the implementations more complex what might be the reason his was only implemented for one of nine backends. When adding something like this and extending the complexity I would prefer that at the same time it gets also *implemented* in all or most or at least most used cases. I want to make clear that from my POV in those cases choosing possible runtime speed over complexity is not always preferable.

The code already tries to hide the cost of the high-quality bicubic scaling by caching, but there are still cases where there's too much scaling done. Since this is only drawing to screen, use only bilinear+mipmap scaling in raster mode, which should be good enough (it's what the "super" scaling VCL algorithm for BmpScaleFlag::Default does as well).

Up until now this has been implemented like in almost all other VCL backends by manually xor-ing pixel values. But that required fetching pixel values from the GPU in Vulkan mode, which is relatively slow. Since some time Skia now has supported writing custom blending modes using the SkBlender class, so it's now possible to drop the hack and support xor drawing directly using a blender that does the operation. This should be both faster and simpler.

2021-11-16try to avoid scaling bitmaps twice in Skia when drawingLuboš Luňák
The scenario is that something scales a bitmap and then asks for it to be drawn (possibly drawn scaled again). One example is OutputDevice::DrawBitmap() subsampling the bitmap that according to c0ce7ca4884f7f6d1 is supposed to improve quality with headless(?) backend, but with Skia it's pointless and it breaks things like caching during repeated drawing, because then GetSkImage() will need to generate a new SkImage each time. Since Skia backend uses delayed scaling, these cases can be sorted out by checking the stored SkImage and using it if suitable, as the original image is as good as the rescaled one, but often it's better - it may be cached, sometimes the scaling operations cancel each other out (often the case in HiDPI mode).

2021-11-16implement HiDPI support for Skia/Mac (tdf#144214)Luboš Luňák
The basic idea is the same as the 'aqua' backend, simply set up a scaling matrix for all drawing. That will take care of the basic drawing everything twice as large, which is twice the resolution. And then blit this data to the window, which expects data this way. Converting back from backing surface needs explicit coordinate conversions, and when converting to a bitmap the bitmap needs to be scaled down in order to appear normally sized. Fortunately I've already implemented delayed scaling, which means that if the bitmap is drawn later again without any modifications, no data would be lost (to be done in a follow-up commit). Unittests occassionally need special handling, as such scaling down to bitmap not being smoothed, because they expect exact color values.

2021-04-06vcl: use PixelFormat enum in SalBitmap interface and backendsTomaž Vajngerl
This changes all backends to use PixelFormat as the input to the SalBitmap::Create method (and all the backends). This is the first part as we need to make sure to also limit the use of GetBitCount method and also use of it in SalGraphics.

2021-03-16fixes for SkiaSalBitmap delayed scaling (tdf#140930)Luboš Luňák
The original idea for delayed scaling was that if a bitmap is to be scaled, only the parameters will be saved and the pixel buffer mBuffer will be resized only on-demand. But this gets complicated by mImage sometimes not being just a cache of mBuffer, but sometimes it is the only data. This is needed so that e.g. OutputDevice::GetBitmap() can operate only on SkImage without possibly ever needing a conversion to the pixel buffer, thus even keeping the data only on the GPU in the Vulkan case. Together with delayed scaling this means that the size of mImage can be either the original size (if Scale() is called with mImage already valid) or the final size (if mImage is created in GetSkImage()). Thus relying on 'mPixelsSize != mSize' as a detection of pending scaling does not always work for mImage. Handle this by using mImage dimensions in cases where relevant.

2021-03-03try to avoid skia alpha blending with fully opaque bitmapsLuboš Luňák
E.g. the document in tdf#140753 has a PNG which technically has an alpha channel, but it's actually completely opaque. Doing this avoids having the pixel data for the separate alpha bitmap, and it also avoids the pointless (somewhat costly in the raster case) alpha blending.
