   = IMAGES LOAD([filename]) FRAME SIZE ([w],[h])
   = IMAGES LOAD([filename] AS [alias]) FRAME SIZE ([w],[h])

The IMAGES LOAD command allows you to load an image and to convert in an array of images. Each image will be of [w]x[h] pixels. Offset will be calculated automatically on the base of the original image.

The command support a set of modern image format, like:

• JPEG baseline & progressive
• PNG 1/2/4/8/16-bit-per-channel
• TGA
• BMP (non-1bpp, non-RLE)
• PSD (composited view only, no extra channels, 8/16 bit-per-channel)
• GIF
• HDR (radiance rgbE format)
• PIC (Softimage PIC)
• PNM (PPM and PGM binary only)

The image will be converted into a way that can be efficiently drawn on the screen. It could be converted into indexed palette, and can be rescaled as well.

Since it is possible to load only one file of the same type at a time, it is necessary to be able to indicate an “alias” with which to exceed this limit. In this regard, there is also the AS syntax, which allows you to load the same file several times but with different names.

  starship = IMAGES LOAD("starship.png") FRAME SIZE (8,8)
  alienAt11 = IMAGES LOAD("alien.png") FRAME SIZE (16,16)
  alien2 = IMAGES LOAD("alien.png" AS "alien2") FRAME SIZE (16,16)
