: Image's texture might be stretched? I came over from Stack Overflow, I'm not really sure if this is the right place to ask this question, I'd like to apologize in advanced. I just finished
I came over from Stack Overflow, I'm not really sure if this is the right place to ask this question, I'd like to apologize in advanced.
I just finished a couple of isometric maps, the first map is an image with a 28712x27744 size. I know how big that is. The reason is that my screen (based on the return values of my program) returns a size of 3840x760 (fullscreen), the program (an RPG Game) should be able to project that size from the image and feature scrolling all along the x and y axis of the image since the image acts as a map.
The image was made at inkscape. But I'm planning on making a texture over at GIMP, the thing is that it takes a heck lot of time so I tried to export the image from inkscape at half the size of the original, but GIMP still runs pretty slowly. I was thinking of going smaller but I feared the the image but appear blurry in-game (I'm not using a commercial engine but a personally made engine so I'm trying to make the resources fit easier).
My question is-
Is there a way to texture this without my pc processing like a snail?
OR
If there's no other way then if I were to downsize it, do you guys have any techniques on how I should tackle the texturing so that it won't appear blocky when enlarged? an example would be those old 2d rpg games (usually from the ps2 era), I noticed that no matter how gigantic the screen goes, the texture doesn't really seem like you're looking at a pixel, instead, it seems like you're looking at a proper image.
I'm really sorry if this was the wrong place, I was thinking if I should post this at gamedev or graphicsdesign, though I chose gd since I might get more people who have proper tips.

You can and probably should cut the image up into tiles. This allows your gane to load each segment separately into the graphics cards memory. But as a side effect it makes texturing easier for you.
PS before you go on make sure your game engine wont choke on your texture size. Many gfx systems have a 8k texture limit. (altough it could have several of those)
I am not an expert on game developement. But an image 28712x27744 as 8 bit RGB tif is about 2.2 Gigabytes in Photoshop. I created a test image. On the Mac Os it is 2.4 G on the disk. I was able to open it in Gimp but it took a while. The image crashed the filter plug-in I tried to use. I think GIMP has issues with large file sizes. You might try to find someone who knows GIMP better than me. There may be some settings you could change...
Remember that when you are going from Inkscape to GIMP, you are going from a vector program (I believe) to a bitmap program.
Also I think in games they have a procedural way of switching from lorez images for large scale views and higher rez as you zoom in.
