Raspbian CreatePicture problem

[KiPSOFT-zz]

Hi;

I'm getting error this command;

Render.CreatePicture(pict, wid, Render.rgb24);

error message: Bad match

My system raspberry pi B+ and Raspbian Jezzy Lite.

Whats my problem ?

Thanks.

Hi! Could you post output of xdpyinfo command on your system, value of Render.rgb24 and value from Render.QueryPictFormat(callback) call?

The code to choose Render.rgb24 is here - https://github.com/sidorares/node-x11/blob/master/lib/ext/render.js#L599-L600

Also what was the visual and depth used to create win?

Hi again;

Thanks for response.

you haven't posted Render.rgb24 so I used this script to figure it out:

var ext = {};

             for (var i=0; i < formats.length; ++i) {
                    var f = formats[i];
                    if (f[2] == 1 && f[10] == 1)
                        ext.mono1 = f[0] ;
                    if (f[2] == 24 && f[3] == 16 && f[5] == 8 && f[7] == 0)
                        ext.rgb24 = f[0];
                    // 1, 32, 16, 255, 8, 255, 0, 255, 24, 255, 0
                    if (f[2] == 32 && f[3] == 16 && f[4] == 255 && f[5] == 8 && f[6] == 255 && f[7] == 0 && f[9] == 24)
                        ext.rgba32 = f[0] ;
                    if (f[2] == 8 && f[10] == 255)
                        ext.a8 = f[0];
                }

console.log(ext);

It prints { mono1: 34, a8: 35, rgba32: 37, rgb24: 55 }

Could you test what happens if you use 56 instead of rgb24?

Also make sure you don't pass 0 as height or width or els you'll get Match error.

If you create client with debug flag you'll see which request generates error:

x11.createConnection({debug: true}, function(err, display) {
   /// ...
});

[KiPSOFT-zz]

i'm test 56 value on CreatePicture still error.

My height and width not zero. i'm testing this code;

x11.createClient({ debug: true },function(err, display) {
    var X = display.client;
    display.client.require('render', function(err, Render) {
        wid = X.AllocID();
        var root = display.screen[0].root;
        var white = display.screen[0].white_pixel;
        var black = display.screen[0].black_pixel;
        genislik = display.screen[0].pixel_width;
        yukseklik = display.screen[0].pixel_height;
        cidWhite = X.AllocID();
        cidBlack = X.AllocID();
        X.CreateWindow(wid, root, 0, 0, 300, 150, 0, 0, 0, 0, {
            backgroundPixel: white,
            eventMask: KeyPress | Exposure
        });

        X.CreateGC(cidBlack, wid, {foreground: black, background: white});
        X.MapWindow(wid);
        Render.QueryPictFormat(function(deger, formats) {
            var pict = X.AllocID();
            Render.CreatePicture(pict, wid, 56);
            console.log(formats);
        });
    });
});

I'll try to reproduce on Pi. Your example works fine in ubuntu/virtualbox

[KiPSOFT-zz]

Thanks.

[KiPSOFT-zz]

Yes this code work in ubuntu. I'm tested on Ubuntu 15.04.

[sdumetz]

I had the same problem today. Forcing the X server to 24 bit depth apparently solves it.

It looks like the pi's default is simply not to 24 bits (I couldn't find any reliable way to check the actual depth...).

I added this to the /boot/config.txt file (found here ):

framebuffer_depth=24
framebuffer_ignore_alpha=1

Didn't took the time to test the other way around though.
