Frequently Asked Questions
If you are seeing crashes in the ArtRage Android apps, you may be able to fix this by following the steps below. Android apps can crash for many reasons, such as lack of memory or corrupted data. If your crash is caused by a bug in ArtRage, we will need to know what happened when you followed these steps, so that we can find and fix the problem.
Before doing any other troubleshooting:
- Check to see if there are any updates available for the app (we may have fixed the problem already!).
- Check how much memory is available on your device (both storage and memory usage when ArtRage is active). If you do not have enough memory left, your device will shut ArtRage down to save memory.
If ArtRage crashes randomly, while starting up, or while creating or working on paintings:
Android apps can crash for a lot of different reasons, including bugs or corrupted resources in the app, operating system bugs or conflicts, and lack of memory. You may be able to fix the problem working through these steps, but if you can’t, you will be able to narrow down the cause and help us troubleshoot more effectively.
- Go to Settings > Application Manager > ArtRage and delete the cache (this will delete any unsaved work, so save your painting first!)
- Go back and delete the Settings (this will delete the licence data and personal preferences, like your last used tools and canvas size, but will not affect your actual paintings).
- Reinstalling the app is also a quick way to reset everything (again, you will not lose your paintings).
If clearing out the app data doesn’t help:
- Browse directly to the ‘/ArtRage’ folder on your device and delete or rename it (if you have any custom presets, you should rename the folder, or save them somewhere). This will clear out any corrupted resources. ArtRage will create a new folder when the app restarts.
If ArtRage only crashes when you go to the gallery:
This is usually caused by either a lack of memory or a corrupted painting. There will usually be a warning notice in the gallery itself if your gallery is too large. The fix is the same for both problems, so it doesn’t matter which one it is.
Browse directly to /ArtRagePaintings on your device and delete or rename it (this is where all your paintings are stored. You should save them somewhere or just rename the folder if you do not want to lose your files). ArtRage will create a new folder when the app restarts.
If you stop seeing any crashes, then you can copy some of your paintings back into the new /ArtRagePaintings folder to work on. If you start seeing crashes again, then either you have added too many paintings or one specific painting is causing the problem and needs to be taken back out again.
If ArtRage still crashes after doing everything else:
If you have followed all the steps above, then you probably can’t fix the problem yourself and will need to contact us.
Contact us directly via the support form. Tell us what device you are using, what operating system version, whether you have followed the steps on this page, and if you have submitted a crash report (we will need to know your device details to identify it).
If you get the option to submit a crash report after a crash, please send it. It gives us data that we can’t get otherwise. If you can spot any pattern (e.g. the crash always happens with a certain preset, painting, or action), please let us know.
Your ArtRage paintings on Android devices are not saved inside the app itself. They are located separately in the /ArtRagePaintings folder on your device, just like photos or documents.
This means that you can freely access this folder and copy files in and out of it. The ArtRage Gallery will scan this folder when the app starts up and load any PTG files inside it.
If you need to reset your ArtRage app data or cache in the Application Manager, this will not affect your paintings. The app data only affects your personal ‘set up’ inside the app (e.g. licence, last used canvas size, unsaved work), not any of the files you create in it.
Note: This is NOT the case for iOS apps, which require all data to be saved as part of the app itself. Deleting the data or app on the iPad or iPhone will also delete all the ArtRage paintings. If you need to move a large gallery off your iPad, please see this tutorial.
ArtRage for Android allows you to import images to create new paintings from other apps on your device (for example, the default Gallery and Photos apps, Dropbox, and other apps that support image export, like Autodesk Sketchbook).
Interacting with other apps is controlled by the Android operating system, not ArtRage. If you chose to set one of these options as the default option and now need to use one of the others, you can reset your default settings in the other application’s settings.
For example, if you have set ArtRage to always import from Dropbox, you would reset your Dropbox default settings (note: this will also reset any other apps that default to Dropbox). Simple go to your Application Manager > Dropbox and look for the ‘Default Settings’ section and reset it (you may also be able to go to Settings > Default Applications > Set as default > Dropbox).
Note: The exact names of the menus may vary on different devices, but the path will be the same.
My images are not recognised by the computer when I export by email
If you export a JPEG, PNG, or PTG file by email from your iPad app and the computer cannot recognise or open it properly, check the file name of the image that was sent as an attachment.
We have seen cases where the email app strips the file format from the name when attaching the file, so your computer cannot recognise what kind of file it is and doesn’t know how to open it. It isn’t our app doing it, so we can’t fix it.
This is easy to fix. If your attached file is just called “Painting”, with no file type (e.g. “Painting.jpg” or “Painting.ptg”), then just save the image to your computer and manually rename it to add the file type extension to the name.
If you can’t open your ArtRage Touch painting files, they are probably too large for the app. There is an issue with some devices with larger screen resolutions overriding the canvas size defaults – basically, they have created paintings too large for the app to re-open.
If you have a licence for a desktop version of ArtRage, then just install that on your Surface Pro (or other device), open them, and change them to be 2048×2048 pixels or less and it should solve it. The free demo will work as well, but it will save the files as much smaller paintings (maximum size is 1280×1024).
If you keep an eye on the canvas size when creating new paintings, you can manually change it down to 2048 pixels or less for width and height and avoid this problem.
There are three different ways to import a photograph as paint to work on directly in the iPad app.
1. Start a new painting from an imported photo.
To do this, go to the Gallery view, click the ‘+’ symbol in the top right, and choose ‘Import Image’. This will automatically create a new image as close to the size of the imported image that ArtRage supports (the max size is 2048×2048).
2. Import a photo into a layer in your current painting.
Open the Layers menu, and tap the cog symbol right at the top (the one for ALL layers). Choose ‘Import Layer’.
3. Copy/paste from the iOS clipboard.
If you have copy an image to the iOS clipboard elsewhere (e.g. if you tap the ‘upload’ arrow on a photo in the gallery, one of the options is ‘Copy’), you can then Paste it as a new layer in ArtRage. This is in the same place as ‘Import Layer’ – open Layers > tap the cog symbol at the top > choose ‘Paste from iOS Clipboard’.
Which export file formats support transparency in ArtRage?ArtRage fully supports transparency in its native PTG format, but if you want to export a transparent image, you need to use PNG, PSD or TIFF file formats. ArtRage does not support transparency when exporting to JPG, GIF and BMP.
- Make sure that the layer or canvas you are currently exporting is already transparent in ArtRage.
- TIFF transparency is only supported when exporting individual layers from the layers menu. It is not supported when exporting the entire canvas.
- We recommend using PNG or PSD, as they will retain the most information and print at the highest quality.
Which export file types support layers?While ArtRage’s PTG format fully supports layers, the only file type that will also support layers when exported is PSD (Photoshop). All other file types will flatten the painting down to a single layer when exported.
I can’t preview the thumbnails for my files with my Steam installation of ArtRage?Because ArtRage uses a unique file format, normal operating systems cannot display the thumbnail image when browsing the files in folders. Normally, there is a special thumbnail viewing program installed as part of ArtRage, but it isn’t possible to include this with Steam installations for Windows operating systems.
Instead, you can download the free demo and take advantage of the thumbnail viewer that is installed along with it.
IMAGE SIZE KEY The recommended image size for perfect printing.
2. Minimum recommendedThe lowest recommended file size.
3. Minimum allowed:The lowest size that the website will accept and may not print at perfectly quality. It is there to give you a choice, in case you cannot upload a larger file.
Note:Any image area left blank (ie. top and bottom if an image is set to ‘fill’) will reproduce as unprinted material. This is not recommended on gallery frames or canvas prints as it will create an undesirable finish within the frame mat and canvas edge.

Can I move my ArtRage iPad paintings to a new iPad?
If you purchase a new iPad device, then you may want to continue working on your existing paintings and move some or all of your ArtRage for iPad gallery to the new tablet.
All PTG files (ArtRage’s file format) can be used in any edition of ArtRage as long as the device can handle that size canvas, so your existing paintings should work just fine on another iPad.
There are a couple of ways to do this.
Use the iPad Backup Function
If you set up the iPad Air using the same Apple account as the first iPad, then you can restore the entire contents from a backup made of the first iPad. This includes the ArtRage files.
Manually Transfer With iTunes
The other way to transfer your files is through iTunes, from one iPad to the other (or to the computer, and from there to the iPad).
There are step by step instructions here: How to access iPad paintings with iTunes
How can I rescue a PTG painting that won’t open in ArtRage?
If you receive an error message and are unable to open a PTG file, then it probably means that your ArtRage painting was were corrupted at some point. Damaged PTG files usually result from interrupted saves (for example, if the computer shuts down or ArtRage crashes). We will do our best to help troubleshoot the source of ArtRage errors, but usually cannot fix corrupted or partial files.
However, if you can see the image thumbnail then that means that the PNG preview image is intact. If you use File > Import Image File to open the damaged files, then it will import the PNG thumbnail.
This PNG file is the full size of your painting and high quality. It won’t rescue your layers or other paint information, but it will give you something to work with.
Backup Save Files
If crashes happen frequently for any reason, or you are working on an important painting, we recommend turning on the Store Backup Files option. You can find it by going to Edit > ArtRage Preferences > Advanced > Store Backup Files.
Adjust the slider to the number of backups you would like to keep.
Important: This function does not save a duplicate file. Instead, it keeps a history of previous saved versions.
Every time you save, it will delete the oldest backup file, and save the latest changes as a separate file, so if you have made important changes, save twice to update the older back up and the file you are actually working on.
What is the PTG Extension?
ArtRage paintings all use a unique, proprietary, file type, the .PTG extension. The file type can only be opened by ArtRage and can be used across all the different editions (including the free demos and iOS versions).
The reason we use a special file type is because ArtRage needs a way to preserve all the unique traditional painting aspects of the program, such as paint thickness, canvas texture, realistic colour mixing, lighting and how the different media should interact. It also records more standard attributes, such as layers and transparency, and preserves ArtRage-specific attributes such as pinned References, tracing images and symmetry.
What does “PTG” stand for?
PTG means “Painting” (PainTinG).
How to share paintings from the iPad
Can I transfer between the iPad and the desktop version of ArtRage?
You certainly can transfer to and from the iPad. The iPad has a range of export options in three image formats (JPG, PNG, PTG).
Choose the Export menu (the small arrow in the centre of the bottom menu bar) while in the gallery view to access the options.
- Send to the iPad ‘My Photos’ Folder (JPG)
- Send to iTunes (JPG or PNG)
- Email it from the iPad (JPG, PNG, PTG)
- Upload it to the internet directly by connecting to a supported app
- Submit it to DeviantART (JPG)
- Share it on Facebook (JPG)
- Export it to online storage apps: DeviantART St.ash, Dropbox, Creative Cloud (PTG, JPG, PNG)
- Print Painting (your iPad will need to be connected to a printer)
If you are trying to work on a painting across both the iPad and the desktop, you have two more options:
- Record a Script on the iPad and play it back on the computer.
- You will need to start the script recording when you are creating the painting (in the canvas settings). You can only play it back on the desktop, but you can replay it as often as you need to, and stop it at any point.
- Exporting a script will appear as an option in the Export menu if a Script is available.
- Transfer files in and out of the iPad using iTunes (You can move files onto the iPad as well with iTunes).
About the file types:
- PTG is the ArtRage proprietary file type. This file will contain all the layers, depth and paint effects from your painting. You can import a different image file to work on, but it will not have layers or any of the special effects.
- JPG is the smallest file type and the most suitable to share online. If you edit JPEGs, you will lose a small amount of quality.
- PNG is the best file type if you wish to continue editing the painting in other programs.
There is a diagram of the various export options here: Exportable File Types for the iPad
Opening PTG files in a different version of ArtRage
Yes. All versions of ArtRage, including the iPad and the Demo, create PTG files and can open and edit these. So any paintings you create in one version (e.g. the Demo) can be continued with another version (e.g. the iPad or ArtRage 4).
Note: If you import an extremely large painting to the iPad, then you may run out of memory.
Access iPad paintings
You can find your ArtRage files in iTunes by accessing the app directly through iTunes.
- Launch iTunes.
- Connect your iPad to your computer with the USB dock cable.
- Select your iPad from the Devices list in the iTunes Library column, then click the Apps tab.
- Now scroll to the bottom of the iTunes window to see the File Sharing area.
- Select ‘ArtRage’. You will see a list of files appear in the right hand window. You can transfer files in and out of this folder.
- Your ‘Exported to iTunes’ files will appear in the list as JPEG or PNG versions.
- iTunes is currently the only way to add PTG files to the iPad.
- “Export to iTunes” simply creates a PNG or JPEG copy that you can access via iTunes, it does not actually ‘send’ it anywhere.
- There is a diagram of the various export options here: Exportable File Types from ArtRage for iPad
What image formats does ArtRage use?ArtRage uses the custom file type “PTG”, and all paintings will be saved in this format. It’s always a good idea to keep a copy of your work in Artrage painting format (PTG), as this format supports layers, paint thickness, paint wetness and so on. However you can also import and export your work as other standard image types.
To save a painting in a non-PTG format, go to File > Export as Image (ArtRage 2) or File > Export Image File (ArtRage 3 & later), then select the format you wish to use.
To load a non-PTG file as a new painting or as a new layer in an existing painting, go to File > Import Image File or Import Image File to Layer.
