Convert PICT to APX

Understanding PICT and APX file formats

PICT is a graphics file format developed by Apple for Macintosh computers. It was widely used for storing both bitmap and vector images, especially in early Mac applications. PICT files typically have the .pict or .pct extension and are now considered legacy formats.

APX is a file extension most commonly associated with ArcPad Layer files, used in GIS (Geographic Information Systems) applications, particularly by Esri's ArcPad software. APX files store map layer data, including spatial and attribute information, and are not standard image files but rather specialized for mapping and geospatial data.

How to convert PICT to APX

Direct conversion from PICT to APX is not straightforward because these formats serve different purposes: PICT is for images, while APX is for GIS data. To achieve this conversion, you must first convert the PICT image into a GIS-compatible raster format (such as TIFF or JPEG), then import it into a GIS application and save or export it as an APX layer.

Recommended software for conversion

• Adobe Photoshop or IrfanView (for converting PICT to TIFF/JPEG):
  File → Save As → TIFF or File → Save As → JPEG
• Esri ArcPad (for creating APX from raster image):
  Layer → Add Layer → [Select TIFF/JPEG], then File → Save Layer As → APX
• QGIS (open-source alternative):
  Layer → Add Layer → Add Raster Layer, then use plugins or export tools to create APX-compatible files

Step-by-step conversion process

1. Open your PICT file in an image editor like Adobe Photoshop or IrfanView.
2. Save the image as a TIFF or JPEG file using File → Save As.
3. Open ArcPad or QGIS and import the saved raster image as a new layer.
4. In ArcPad, use File → Save Layer As → APX to export the layer in APX format.

Tips and considerations

• Ensure your image is georeferenced if you want it to align correctly in GIS software.
• APX files are not standard image files; they are used for mapping and spatial data.
• If you need to convert many files, consider batch processing tools in Photoshop or IrfanView.
