How to convert PGM to DDS

Converting PGM to DDS is very easy with Image Converter Plus. In Windows Explorer, select a PGM image and click your right mouse button. In the context menu, select Convert to submenu and click Custom convert line.

Add files to Custom conversion.

The list will already contain images selected from Windows Explorer.

To add other files, press Add image button and select some more files in PGM format to be converted to DDS . Select DDS format as target format.

Expand "Save images in DDS format" group and adjust any needed settings. The format settings only support color depth selection: 

      	R8G8B8: (24 bits per pixel, R:8, G:8, B:8)
      	R5G6B5: (16 bits per pixel, R:5, G:6, B:5)
      	A8R8G8B8: (32 bits per pixel, A:8, R:8, G:8, B:8)
      	A8B8G8R8: (32 bits per pixel, A:8, B:8, G:8, R:8)
      	X8R8G8B8: (32 bits per pixel, A:x, R:8, G:8, B:8)
      	X8B8G8R8: (32 bits per pixel, A:x, B:8, G:8, R:8)
      	A1R5G5B5: (16 bits per pixel, A:1, R:5, G:5, B:5)
      	X1R5G5B5: (16 bits per pixel, A:x, R:5, G:5, B:5)
      	L8: (8 bits per pixel, luminance:8)
      	A8L8: (16 bits per pixel, A:8, L:8)
      	DXT1: (compressed, 1-bit alpha)
      	DXT2: (compressed, 4-bit premultiplied alpha)
      	DXT3: (compressed, 4-bit nonpremultiplied alpha)
      	DXT4: (compressed, interpolated premultiplied alpha)
      	DXT5: (compressed, interpolated nonpremultiplied alpha)

  • MIP maps are pre-calculated, optimized collections of bitmap images that accompany a main texture, intended to increase rendering speed and reduce artifacts.

If the texture has a basic size of 256 by 256 pixels (textures are typically square and must have side lengths equal to a power of 2), then the associated mipmap set may contain a series of 8 images, each one-fourth the size of the previous one: 128x128 pixels, 64x64, 32x32, 16x16, 8x8, 4x4, 2x2, 1x1 (a single pixel). If, for example, a scene is rendering this texture in a space of 40x40 pixels, then an interpolation of the 64x64 and the 32x32 mipmaps would be used. The simplest way to generate these textures is by successive averaging, however more sophisticated algorithms (perhaps based on signal processing and Fourier transforms) can also be used.
