ImageCrop is a tool that allows photos to be cropped with a desired aspect ratio. Gamma correction and gray scale conversion as well as basic printing is supported.
Jpegview is a tool that allows easy viewing of JPEG format images.
Files to view are selected using a visual browser that caches small thumbnail
images. Basic printing is supported.
ImgConvert allows multiple files to be selected (using the same visual
browser as JpegView) and then converted to different file formats.
The supported input formats are JPEG, BMP, GIF and PPM. The supported
output formats are JPEG, BMP, GIF, PPM, MPEG movie and animated GIF.
Output options allow the image size to be scaled by a factor or constrained
to fit into a particular window size. The JPEG compression quality
can also be adjusted. This tool is very useful for shrinking a bunch
of images taken from a high resolution digital camera before emailing them.
It is also useful for making stop frame animations as shown below:
ImgPrint makes it easy to print out pictures onto a sheet of printer paper.
The same visual browser as ImgConvert and JpegView is used to select the
images to print. The selected images are rotated to fit onto the
page. Options allow the number of pictures per page to be set.
Color is a tool to teach about the differences between light and color
mixing. Sliders can be manipulated to mix different amounts of light
and color to try to match a random color.
