Hi All,

I watch a problem with backgrop in a standalone it work fine on OSX and windows

I set the backdrop to the id on an image of the stack but i see un rectangle 100/80 at the topleft of the screen but there is not backdrop.

What is the best way for a really backdrop on Linux?

Thank

Jean-Marc

Hi Jean-Marc,

Are you sure you used the right dimensions? This is what the documentation says about it:

To be used as a pattern on Mac OS systems, an image must be 128x128 pixels or less, and both its height and width must be a power of 2. To be used on Windows and Unix systems, height and width must be divisible by 8. To be used as a fully cross-platform pattern, both an image's dimensions should be one of 8, 16, 32, 64, or 128.

And of course, pray that it works :-) This kind of features, which involve special windows, can be quite tricky with Linux.

Best,

Mark

Hi Jean-Marc,

It looks like there are a few execution errors in your stack. Sorry, I have no additional information.

At some point, a repeat loops seems to outline object on the screen alternately, with big black borders. This causes processor uses to go up and makes the fan take off sky high. It seems that you need to adjust this to avoid locking up the interface and you'll need to make clear what is going on and how to stop it.

Best,

Mark

Hi Mark,

Thank for this feed-back.

The processLoop is destined to handicaped people

Type optionKey to stop the process loop (or select the btn "mouse" by a mouseup when the processLoop is on)

The vietnamien proverb is only in french. I try a english translation

"Before you go up a tiger, it is a good idea learning to go down"

The btns "mouse" and "Processlopp" (at right of the nousebtn) works like a radiobutton.

If the hilite of btn "Mouse" is true you can use with the mouse or with a joystick. The loop is ooff

If not, the hilite of btn Processlopp is true and the loop is on

When you quit, the navigation mode is saved in one file and read on opnstack to set the preferences.

Hi Jean-Marc,

Thanks for the explanations. Now I understand how it works. I still believe that you need to change the repeat loop though. I guess you need to use the send command instead of a repeat loop. It would avoid a lot of annoyance.

Best,

Mark

Thank one more mark,

In fact, there is several loop with a wait at the end of each.

What is the difference if i send a message at the same rythm

Hi Jean-Marc,

By using the send command (send in 0 millisecs) you give Revolution time to clean up and the processor needs to work less hard.

Best,

Mark

Hi Mark,

We are going out the original topic
I move our exchanges on a new topic "tools to watch the processor work" in "talking revolution"

My experience of the built-in Backdrop has never been very satisfactory, so I tend to use a fake one:
