[ATOMIC FE] Problema con colores y layout

Thanks a lot, Youki. I´ll send you in a moment.

The problem is:

1.- I create a background with a png scroll over it.

2.- I want this png to be transparent. I´m not sure what to use alpha channel inside layout editor or just alpha channel from image.

3.- If I launch de layout, it doesn´t work at all.

4.- If I remove the background, and I configure the front-end at 640x480 (the layout is at 1024x768), it works.

5.- But if I leave the front-end at 1024x768, the layout doesn´t work. Actually I can see some white lines moving in the screen from right to left and slowly moving down one pixel when each line ends (it seems memory problem for me, but I don´t know much about programming )

Ok, i wait your layout, i will check that as soon as i receive it.

Can you remind me your configuration ? Computer ? Memory? Graphic card?


For "Transparent" color , there are 3 mode in Atomic .

You have a full transparent color that defined at the layout level. (example, i want Pink (RGB(255,255,0) be transparent for images. You can set that in Layout properties.

You have the Aphablending value on object. This value from 0 to 255 , define the level of transparency for the selected object. 255 not transparence, 0 totally transpanrent. between it will be more or less transparent. The Alpha value acts on the entire object. the same value is applied to each point of the object.

You have the gradual Alpha blending. In this mode for a given image all point can have a different value of Transparency. This mode uses "gradual mask" . a Gradual mask is a image mask of exact size of the displayed image you wan use gradual alpha. This gradual mask is a image done only with gray level. Each level of gray match with one value of transparency. The layout called "Totoleouf16" use that feature on the reflection object , have a look.

AtomicFe doesn't manage alpha channel stored in the png. These alpha channel requires 32bit/pixel image , that's too much. I do almost the same effect with 16bit/pixel image using lot of less memory.

Ok, it helps me a lot

I´m using an AMD ATHLON XP 2400 with 512MB of RAM and a NVidia 5700u with 128MB of RAM.

About transparencies, I was wrong, I though your FE used the alpha channel of png images. By the way, jpg aren´t supported, right?

I´m going to make some tests now.

Thanks again.

By the way, jpg aren´t supported, right?

In fact AtomicFe can load Jpg , but not the layout editor that uses only Png.

So it is better to work only with Png.

Just testing with the background.

I´ve converted the background to 8bit png. If I show it in the layout editor, it looks fine, but when I test it in the FE using the option in the editor, I get this:



This is what happens:

1.- I can see the background right in the layout editor at 1600x1200 and 32bit color desktop

2.- When I press the button to test it in the FE, windows changes the resolution to 1024x768 and the colours of the background are bad, it seems Atomic FE is lowering the colour depth.

3.- I see the background working in the FE but with lower colours as the screenshot shows.

1.- I can see the background right in the layout editor at 1600x1200 and 32bit color desktop

That's normal , the LayoutEditor uses the Window Desktop color depht .

When I press the button to test it in the FE, windows changes the resolution to 1024x768 and the colours of the background are bad, it seems Atomic FE is lowering the colour depth.

AtomicFE runs always in 16bit/pixel mode. So it change the color depht.
For the resolution, The layout Editor use the resolution that is set in current start up config. So try to change with AtomicManager.exe the resolution of the file AtomicFe019.cfg , and put 1600x1200 , i guess there is 1024x768 .

3.- I see the background working in the FE but with lower colours as the screenshot shows.

that's normal , as i said , Atomic works in 16bit/pixel mode , if you give it a 32bit/pixel image it will display it but with lower colours.

Youki, but the image is at 8bit

I just did the same test.

I converted your background in 8 bit. and run it in Atomic. On my machine, there is no problem. Color are the same.

But i guess it could change depending on the graphic card you have and your video driver.

Because windows need to convert your 8 bit image to 16 bit image to display it.
8 bit image is a palettized mode , 16 bit one not. So the drivers is doing some mathematic to convert the image. And may be the result can differ in function depending of the driver.

But as i said , the best thing to do with Atomic , is to work directly with 16bit images. That's the mode where Atomic works.

Hi, Youki, I´ve found that Photoshop 7 (wich is what I use) has a bug working with 16bits png. There is a freeware plugin called SuperPNG wich resolves the bug and gives photoshop more options

I´ll try to test it this night.
