Spence's Republic

Taxes collected are not only used for whiskey.

I needed a place to list and share the coding projects I've done and this is it.

Raison d'etre

I look after PastForward, a digital repository about the hisory of Winnipeg. Our major, self-hosted collections are of historical postcards. Some of the work involves scanning postcards and processing those images for publication. Sometimes I write scripts to help with this. These are some of them.

postcardScanSimple.exe - An interface to the Windows command line scanning software, CMDTWAIN that allows for scan approval and automates naming to keep document fronts and backs together.

It asks for a document set (binder) name, creates a folder for it, and outputs scans files following the pattern (x)f.bmp, (x)b.bmp, (x+1)f.bmp, (x+1)b.bmp, ..., (x+n)f.bmp, (x+n)b.bmp.
findDocsInScanAndSeparate.ps1 - A PowerShell script to use ImageMagick to find documents arranged vertically in a scanned image and crop out each into separate images.

It turns this into this given any number and size of cards in the original.
