Using Petmate to edit Dir Art

Petmate 0.7.0 adds experimental support for editing directory art in C64 .d64 disk image files.

The process of making directory art with Petmate is as follows:

  1. Create a 16xN screen in Petmate. (Or alternatively, load in a .d64 that already contains several directory entries.)
  2. Export the 16xN screen as a .json file.
  3. Use c1541js to patch your art into a .d64 file. The .d64 file must contain an appropriate amount of directory entries, you can use f.ex. VICE’s c1541 tool to author such .d64 files.

A command line example for step #3:

Let’s say you have a .d64 file called demo1.d64 and your dir art is exported into a file called dirart.json. Run the following command:

At the time of writing (2019-03-16), Petmate doesn’t validate that the contents of your dir art make sense as directory entries. It will just write whatever screencodes you used in your Petmate screen. The special character control codes will be shown more prominently in future Petmate versions.

Processing PETSCII content

Petmate 0.7 adds a new .json export format. It is intended to stay unchanged across Petmate versions and its intended to be easy to consume by content processing scripts written in say Python or JavaScript.

The structure of Petmate’s .json export format is pretty simple:

Importing PETSCII from PNG image files

As of version 0.6.0, Petmate supports importing PETSCII from PNG images. This import feature matches pixel data against the C64 ROM charsets (upper and lower case fonts). There is no “fuzzy” machine vision style matching, the code doing the import is looking for a pixel perfect match. This means images that have been scaled (double pixeled or other scale ratio) cannot currently be imported. The PNG importer also expects the image dimensions and borders to match those of VICE:

  • 320x200 for borderless images
  • 384x272 for images with border (left and right border width 32 pixels, top border 35 pixels, bottom 37 pixels).

Colors are matched by quantizing the input pixels into indexed color by looking at the closest mean square error against all the color palettes supported by Petmate, and picking the match that has the smallest mean square error. If the input image contains colors that are wildly different from the Petmate prebaked palettes, some colors may come out wrong. Please report any problems via GitHub issues.

Preferences

The settings are saved in the following location:

  • macOS: ~/Library/Application Support/Petmate/Settings
  • Windows: %APPDATA%/Petmate/Settings
  • Linux: $XDG_CONFIG_HOME/Petmate or ~/.config/Petmate

Petmate 0.8.2 (2020-02-11)

  • Add an integer scale PNG export option for allowing to scale width/height up by an integer. Previously only doubling width and height was supported. Thank you https://github.com/Krad23 for the pull request! (#187)
  • Custom fonts are now supported in PRG export (#183)
  • Add an about menu item for Linux and Windows. Handy for looking up the current Petmate version. (#186)
  • Upgrade to Electron 8.0.

Petmate 0.8.1 (2020-01-04)

  • Add support for setting up custom fonts when exporting a stand-alone assembly file.
  • Add CA65 and c64jasm support for assembly export (#166)
  • Fix gif export bug with more than 64 frame gif anims (#166)

Petmate 0.8.0 (2019-12-17)

  • Add custom charsets (#174). You can load .64c font files from http://kofler.dot.at/c64/font_01.html. Fonts cannot be edited within Petmate – but this will probably get added in later releases.
  • Increase the size of gif Frame delay input width (#165)
  • Choose different outline color for a defined brush opposed to an empty one (#163)

Petmate 0.7.1 (2019-06-03)

  • Add SEQ file format import and export. Thanks @sixofdloc and @manuelvio for your contribution!
  • Fix a bug that caused most keyboard shortcuts from not working when loading a file. Affected platforms: Windows and Linux. This was a mega irritating bug that was possible to work-around by switching to another app and then back to Petmate. (#161)

Petmate 0.7.0 (2019-03-16)

  • Arbitrary sized PETSCII canvas (edit the 40x25 text below the new screen + button and hit +) (#20)
  • Pan/zoom the PETSCII canvas
  • A new .json export format intended to be easy to consume by content processing scripts.
  • Prompt for cancel/quit if unsaved changes when closing the main window or quitting. (#33)
  • Support importing Dir art from .d64 files.
  • Register recently opened/saved .petmate to the OS to make recently edited .petmate files show up on macOS Dock or Windows JumpList. (#133)

  • Make open/save dialogs modal (#136)
  • Display decimal value of a char in addition to hex. (#141)
  • Bug fix: disable GPU rendering. This caused slowdown with larger than 40x25 canvases and forced bilinear filtering instead of nearest-neighbor for scaled canvas.

Petmate 0.6.1 (2019-02-12)

  • Bug fix: PNG export crashed Petmate on Windows. Fixed by upgrading Electron to version 4.0.4.
  • Bug fix: screen name editing only ever updated the currently selected screen name. (#128)

  • Remove screen name validation pattern (#124)
  • Port all code to TypeScript. This was a really big change – found and fixed some bugs but may have introduced new ones. Please report any findings!
