Hi pauljiao,

Thanks for your answer, but please have a heart and read my specification. There are still alias effects and the ring should be 100% transparent and the surrounding area should not be.

The very simple problem seems to be more and more an unsolvable problem...

@ BRT Community: What does your development team say?

@ all: Does anybody know a solution?

Hi pauljiao,

sorry, my last thank was for the reply from BRT Community. I undesignedly overlooked your reply. Thank you for you reply, but I hope you noticed that I had criticized the alias effects in the example from BRT Community, not that in my example. Yes, the alias effect is absolutely visible on the hardware from the BRT Community's example.

@ BRT Community: I still hope for a good solution :)

Hello,

this is no option because the elements have to move on the screen independently and this is just the basic concept for many more following objects on the screen...

Is there another solution?

Hallo,

Thank you for your answer. But as you can see in your example there are unfortunately alias affects which I have to avoid and you don't use transparency (see picture attached). I thought it is possible to simply create the ring in the alpha channel and then combine the channel using BLEND_FUNC with the gradient background. But this doesn't work. Do you have an other solution?

Hello,

here is my display list. But in the heat of battle it seems I have not stored the version I have sent in the picture. As you can see, in the version below there is a gray dot in the middle.

CLEAR(1, 1, 1)
CMD_GRADIENT(17, 64, 0x0075AF, 230, 226, 0xA6F1FF)

COLOR_MASK(0, 0, 0, 1)
BLEND_FUNC(ONE, ONE_MINUS_SRC_ALPHA)
COLOR_A(255)
BEGIN(POINTS)            
POINT_SIZE(1000)
VERTEX2II(133, 176, 0, 0)

COLOR_MASK(1, 1, 1, 0)   
BLEND_FUNC(ONE_MINUS_DST_ALPHA, SRC_ALPHA)
BEGIN(RECTS)            
VERTEX2II(0, 0, 0, 0)         
VERTEX2II(239, 319, 0, 0)

COLOR_MASK(0, 0, 0, 1)
COLOR_A(128)
BLEND_FUNC(ZERO, ONE_MINUS_SRC_ALPHA)
BEGIN(POINTS)            
POINT_SIZE(500)
VERTEX2II(133, 177, 0, 0)


COLOR_MASK(1, 1, 1, 0)         
BLEND_FUNC(ONE_MINUS_DST_ALPHA, DST_ALPHA)
BEGIN(RECTS)            
VERTEX2II(0, 0, 0, 0)         
VERTEX2II(239, 319, 0, 0)

Hi,

thank you for your answer. But unfortunately it doesn't help me. The gf2book (The Gameduino 2) I already know very well, but it doesn't help me, too. I already programmed complex blending operations, but this problem which I described does not want to be solved... scissor and stencil are not helpful in my case.
I would be very grateful for a principal code for the problem.

In the attachments you can see a screenshot of my principal purpose. But as you can see
- there are alias effects,
- the gradient in the inner circle is not the same like outside the circle

Hello,

I use the EVE Screen Editor v3.1.2 with a FT801 device, and I can not solve the following problem:
I want to paint an image on the screen, which has basically two "layers". On the first, rear (in the background) layer there should be a gradient. On the second, front Layer I want to paint a half transparent (alpha = 128) white surface so that the gradient shines through that surface. That surface should be interrupted by a wide contour of a circle, so that you see the rear layer with the gradient along that contour. All edges should be painted with antialias.
I have tried so many solving approaches and combinations of the standard commands like CLEAR, CMD_GRADIENT, COLOR_MASK, COLOR_A, ALPHA_FUNC, VERTEX2II, ... but dont get it.

Who can help me???
