Load image in Kroms

[Krom]

Why not
You can load a height map from Google search and use it. Also it could be used to make image-maps, you know, color section into green-yellow-brown-blue to make a sort of picture as well with height

Never used the load image thing... and by the looks of it, probably never will.

Yeah I'm not saying that it isn't usful, but just that I don't think I will ever be in situation where it will be effective.

Hey,

sorry for necroposting in this topic, but can anyone tell me what I'm doing wrong here?

Height directly into color (0-100)


Height*2.55 (0-255 (8bit) radius)


P.S. I'm using m1 (TSK version)

[Krom]

You are doing everything right, but whats the problem?

[Thunderwolf]

The problem is that when I use that load image thingy, it doesn't look like the original (well, it almost looks like the original, but not completely).

Loaded your map editor twice with tsk m1 loaded, then loaded the heightmap in one of them, it looked 'different'...

b.t.w. Does your editor also do something with DirectX? when the overwritten ddraw.dll is in the knights and merchants folder, the map editor doesn't show up... when renaming or removing the file again it works...

[Krom]

Maybe the way you've got the "original" image changed it somehow? I don't remember my code by line, but it's pretty straightforward - replace maps height with data from image. Anyway the thing is to let you create relief in Photoshop and then import it, nothing more. Although it's interesting what else could be done with this function

[Thunderwolf]

I'll try playing around with it for a bit more...

This is my current (C#) code:

  Code:

Bitmap bmp = new Bitmap(width, height); for (int i = 0; i < width; i++) {     for (int j = 0; j < height; j++)     {         //put block data at coords into blockData         offset = (width * i) + j;         for (int k = 8 + (offset * 23); k < 23 + 8 + (offset * 23); k++)         {             blockData[k - (8 + (23 * offset))] = allBytes[k];         }         int heightInBMP = blockData[2];         Color c = new Color();         heightInBMP = Convert.ToInt32(Convert.ToDouble(heightInBMP) * 2.55);         c = Color.FromArgb(heightInBMP, heightInBMP, heightInBMP);         bmp.SetPixel(j, i, c);     } } bmp.Save("heightmap.bmp", System.Drawing.Imaging.ImageFormat.Bmp);[/quote]

  Code:

Convert.ToInt32(Convert.ToDouble(heightInBMP) * 2.55); [/quote] Why??? You don't need doubles, and you certainly don't need to use Convert (which is evil!) [code](heightInBMP * 255)/100[/quote]

[Krom]

Also keep in mind that all values ahould be unsigned.. probably you already did, but just in case

[Thunderwolf]

  Code:

Convert.ToInt32(Convert.ToDouble(heightInBMP) * 2.55); [/quote] Why??? You don't need doubles, and you certainly don't need to use Convert (which is evil!) [code](heightInBMP * 255)/100[/quote][/quote] yeah.. uh.. I did write that code quickly.. updated it now though, it does generate the same image... [code]Also keep in mind that all values ahould be unsigned.. probably you already did, but just in case[/quote] bitmap.setpixel doesn't accept uint (?)... all values are positive though.
