I am developing a 4-way scrolling game which will build constantly off of a tilesheet. However, when I paste an image to the screen, it loses a lot of quality. In fact, it looks terrible. All the fine details disappear and the pixels appear blurred together. This happens when I paste bmps and jpegs.
Am I doing something wrong?

load image "my_image.png", imageID, 1

The final ",1" turns off filtering which causes the blurred texture.

How do you load an image so that the filtering is still on? And why does the number 1 affect it?

Weird, I was wondering about that too.

The one value is just a flag to tell the render engine to not apply mip mapping to the texture. There's no magic to it. TGC routinely adds functionality that way to various commands. Some are documented and others are not.

If you want blurry images (say for terrain), do not use the additional parameters or try ",0".

When I loaded the bitmaps and jpegs to be pasted, I only gave the filename and the image ID. I did not put a third number.

( load image "c:\", 1 )

I tried what you said and appended a "1" to my image-loading statement. They came out pixel-perfect. Thanks!

One question, though. Is more video memory taken up when you load images this way?

Same image size means same memory size. But, I imagine that they should load faster since less processing is required.

Its possible it's even smaller (no Multum in Parvum-map, aka mipmap)
