The WorkShop Visual Pixmap Editor can read and write a variety of format types.
However, not all types written by the Pixmap Editor can be read back in. In particular, although WorkShop Visual can write XPM 1 and XPM 3 format, together with Microsoft Windows bitmaps and icons, the Editor can only read XPM 3 format and/or X bitmap format files.
You may have attempted to read and XPM 1 or Microsoft Windows image which the Editor cannot handle.
