Weathermap Editor 0.9 Problem

[Howie]

One could replace the half-red color by magenta :

Code: Select all

$nothing=imagecolorallocate($node_im, 255, 0, 255); 

I doubt there are a lot of images/icons using that one.

No, but it is in the default SCALE, so if you we using node targets, that would become transparent. I suspect the "best" answer is some much more random colour like 13,99,201, but it's still second best to actual working alpha support (not just transparency). I'll add the SET option in 0.91, so folks who are stuck with this can enable it.

This is to fix the Debian GD library problem:

download libgd2-xpm_2.0.34~rc1-2_i386.deb

(it is available from ftp.debian.org/debian/pool/main/libg/libgd2/libgd2-xpm_2.0.34~rc1-2_i386.deb)

run the following:

dpkg -i libgd2-xpm_2.0.34~rc1-2_i386.deb

I then did a reboot and now I can use the original line ($nothing=imagecolorallocatealpha($node_im, 128, 0, 0,127);) and have transparency

Many thanks again!

And without the fixed GD library, the following lines changed/added in Weathermap.class.php (as you suggested) work well too:

(first line is line number 1155)

#$nothing=imagecolorallocatealpha($node_im,128,0,0,127);
#$nothing=imagecolorallocate($node_im, 128, 0, 0);
$nothing=imagecolorallocate($node_im, 255, 0, 255);
imagefill($node_im, 0, 0, $nothing);
imagecolortransparent($node_im, $nothing);

Hi.

I've been busy with that alpha. So I tried to replace the following code :

Code: Select all

// create an image of that size and draw into it
$node_im=imagecreatetruecolor($bbox_x2 - $bbox_x1 , $bbox_y2 - $bbox_y1 );
imageSaveAlpha($node_im, true);
// ImageAlphaBlending($node_im, true);
$nothing=imagecolorallocatealpha($node_im,128,0,0,127);
imagefill($node_im, 0, 0, $nothing);

by this one :

Code: Select all

$temp_width = $bbox_x2 - $bbox_x1;
$temp_height = $bbox_y2 - $bbox_y1;
$node_im=imagecreatetruecolor($temp_width , $temp_height );               

imagealphablending($node_im, FALSE);
imagesavealpha($node_im,TRUE); 
$nothing = imagecolorexactalpha($node_im,128,0,0,127);
imagefilledrectangle($node_im,0,0,$temp_width,$temp_height,$nothing);

It seems to work. Can someone confirm this, please ?

Tested and working - good job!
