[RESOLVED] PNG & Transparent color

[Fustel]

And now feedling with the RMVX autotiles...

As I am trying to use custom autotiles in RMVX, using some free & easy-to-use tools (Paint, PhotoFiltre), I encouter the following problem: every time I open a .PNG file, its transparent color is replaced with a king of white. 'till then, I may not really a problem, because you always can declare this white-color to be the transparent colorwhen imprting image in the Ressource Manager. Just..... this same color is used as real-colors by some autotiles in the file, like coastal borders in TileA1, snow fields in TileA2, etc..., and therfore some part of thesz tiles also become transparent.

How could I manage this annoying phenomena, and whit what (free & easy-to-use) tool ?

Not THAT user-friendly, but at last, this is a workable solution.

Thanks.

And if someone has a good explanation on the what-and-how of the PNG files and their transparent colore, please tell us. Perhaps this may help on using our prefered image editors.

i personally like using that, it's one of the much more user friendlies
transparency colors are normally not set in rpg maker unless you use the import tool

wade through the text and something might be explained

Some image editors (e.g. Pre-Vista / Win 7 MS-Paint, et.al.) do not support transparency. they replace fully transparent pixels with the current background color, or an arbitrary white, black, or green when you open an image. Get a better image editor (Gimp, PS, PSP, Graphics Gale, ...) or Flood fill the white background with a color that's not used in your image & use the import transparency in RM.

That last solution isn't nearly as pretty, though. I say that because, when you import a PNG with transparency, RMXP uses the full range of transparency, as opposed to the transparent/opaque offered by the import function.

As someone asked for a PNG reference, there's one written by me a few years ago that you can find here. It doesn't hold everything there is to know (man, by know I would've filled pages with my PNG knowledge probably XD ), but it should give you starting ideas... I just edited out a few minor things that were a tad wrong or less clear than they should be. ^^

Ok... to close the subject, and after giving a try to all of the tools, let's say Paint.net is definitively THE solution.

Thanks all for all your wise advices
