Common Error Messages

If Resizer encounters errors as it processes files it will log these and the first 20 errors will be displayed at the end of the job.

Hint

It is in general the case that where there are more than 20 errors for a given job, that they are usually of the same type or of a small number of types that are likely to appear among the first 20 errors. To view the next 20 without fixing the problem for the first 20, you need to remove the first 20 problematic files from the Folder In temporarily. Since the files are processed alphabetically you can usually simply remove all files up to the required point in the alphabet.

Note

If an extension of a filename is not among Resizer’s supported file formats, it will simply ignore these files and will not log these as errors.

The most common error types are listed below.

Memory Error

This will generally affect large files, depending on your computer’s capabitilies. The files need not be a large in size, they can simply have many pixels. The current version of Resizer is not suitable for very large images so other software must be used to bring these to within common sizes.

Hint

Memory Errors on a given image may affect subsequent images in the same job which would otherwise not run into memory problems. It is therefore advisable to run larger images separately to smaller ones. One rough but easily implemented solution is to use Windows Explorer to order your images by Size and then move all those above a certain size into a separate folder, so that you can run two jobs instead of one, thus reducing the number of Memory Errors. However, this will not always guarantee success as file size and pixel size are not always proportional and the size of the input file is not the only cause of Memory Errors.

Unsupported BMP compression

A number of bmp files are compressed using algorithms that Resizer does not understand. We are considering supporting these compression types in future, but for now these are unsupported.

Broken Data Stream when Reading Image File

This error is similar to the MemoryError above and affects larger files.
