Example a/image_formats: Image reading and writing example.

This example tests the reading and writing of many different image formats. image_formats" /> the tree is from the the Paria River Canyon in Arizona, USA. It makes me think of Jeremiah 17:8.

Screenshot of example a/image_formats

The comfile run by this example is as follows:

#image_formats.com

#For backwards compatibility we force .rgb to be read assuming SGI format.
gfx create texture tree image example tree.rgb linear clamp;
gfx create texture waterfall image example waterfall.tif linear clamp;
gfx create win 1;
gfx mod win 1 layout width 400 height 400;
gfx mod win 1 back texture tree tex_placement 10 -10 380 380;

#The file extension is used to determine the file format.  By
#prefixing a different extension you can override the format without
#changing the filename.
gfx print win 1 file sgi:image1.rgb;
gfx print win 1 file image2.tif;
#When converting to an indexed format, the alpha background gets lost,
#so use rgb to retrieve the image without alpha
gfx print win 1 file image3.gif format rgb;
#Postscript format renders the alpha as nothing
gfx print win 1 file image4.ps format rgb;
gfx print win 1 file image5.bmp format rgb;
gfx print win 1 file image6.jpg;

#Check that we can read these back in
gfx create texture image1 image image1.rgb;
gfx mod win 1 back texture image1;
gfx create texture image2 image image2.tif;
gfx mod win 1 back texture image2;
gfx create texture image3 image image3.gif;
gfx mod win 1 back texture image3;
gfx create texture image5 image image5.bmp;
gfx mod win 1 back texture image5;
gfx create texture image6 image image6.jpg;
gfx mod win 1 back texture image6;
gfx;
