RenderTarget Bug?

antix

I am drawing 2 bitmaps to a RenderTarget. Before drawing each bitmap I clear the area where it will be positioned inside the RenderTarget. This is causing some issues as some areas outside the bounds of my clear are being cleared. In the image attached you can see the yellow area which should not be filled, but somehow it is.

Can anyone tell me if I'm doing something wrong or if there is a bug in RenderTarget clear?

local bitmap, x, y   local atlas = RenderTarget.new(1536, 1536)   x, y = 512, 0 bitmap = Bitmap.new(Texture.new("blue.png", true)) print("blue, x="..x..", y="..y..", w="..bitmap:getWidth()..", h="..bitmap:getHeight()) atlas:clear(0x008888, 1, x, y, bitmap:getWidth(), bitmap:getHeight()) bitmap:setPosition(x, y) atlas:draw(bitmap)   x, y = 0, 512 bitmap = Bitmap.new(Texture.new("red.png", true)) print("red, x="..x..", y="..y..", w="..bitmap:getWidth()..", h="..bitmap:getHeight()) atlas:clear(0x888800, 1, x, y, bitmap:getWidth(), bitmap:getHeight()) bitmap:setPosition(x, y) atlas:draw(bitmap)   bitmap = Bitmap.new(atlas) bitmap:setScale(320 / 1536) stage:addChild(bitmap)

So is this a bug or am I doing something wrong? I can;t proceed either way until I know (

Moved my thread to the Bugs sub forum in the hope that somebody might respond )

Hi @antix, sorry for not looking at this earlier. I played a little with your sample code and yes it looks like a bug, or rather two bugs: clear size is wrong, and color seems wrong too... I'll have a look at the code in gideros.

Bug confirmed, and now fixed in gideros source code

@hgy29 - Coolness. Would that fix maybe make it into the new release that's due anytime now?

I am afraid it won't, it missed the train by half a day... unless we find out some show stopper the 2016.4 is ready to be published right now

Ahh, well, next release then. I can still workaround it for now by clearing and redrawing the whole RenderTarget, it just won't be as fast or efficient for a while
