Crop&Convert MLx Home | MLx menu | MLx buttons | Widgets | Index | What's New

These are utilities for scaling (and optionally cropping) data, and storing the resulting files in another folder. This allows examination of data using Adobe Photoshop, and making catalogs using utilities such as Aldus Fetch, or Kodak Shoebox. Other image analysis software may use these tools for pre-processing.

The actions are controlled by parameters:

Parameters: set the parameters that are in bold. top

• Clip_new_file_name_from
• crop_bdr - This parameter has been eliminated from crop&scale. Use the MLX crop_bdr parameter, accessed with the Rect... button.
• edenominator_array_name
• file_read_function
• file_type_test
• im_type
• input_dir
• output_dir
• output_file_type
• pct_outliers
• scaling
• transpose
• ~doit - Selecting this is the same as using the Crop/C->Doit menu.

• Getting started
• Time to completion

The output_file_type parameter (see the {... setup} menu) controls the output file type, which defaults to TIFF. Raw 8 bit files is the other option. The image dimensions are printed to the listener - this information is often useful when attempting to read raw formatted images.

Time to Completion top - How long will it take?

Estimate time to completion available with the {MLx - loop monitor} menu.

Getting Started top

To use:

1. Specify the input_dir and output_dir folders {MLx - Crop/Convert - Parameters}.
2. Set other parameters if you want special scaling, transposing, or cropping. Cropping will occur according to the crop_bdr mlx parameter. Set the rectangle using the MLx Rect... button. If this parameter is not set, no cropping takes place.
3. {MLx - Crop/Convert - doit}. Select the desired files. Be sure to omit any .doc files.

Scaling parameter. Scaling... button. | top

• Normal Min and max of each image go to 0 and 255 respectively.
• Pct Outliers Same as the Scale...->Clip button.
• w_limits Manually input limits used. Image pixels outside this range are clipped.
• none Images are not scaled.
• find_global_limitsThis choice makes two scans of all of the selected files. It finds the global min and max in the first pass, then scales all of the files (w_limits) using these limits.
