What is the difference between the demo version and the registered version?
The demo version enables you to try the application before actually buying it. There's neither use limit nor time limit for trying the demo version. Here are the only limitations:
For outputting an image file: you will see the words "Unregistered copy" written in white and the Prizmo icon on the output image.
For outputting a text file or a business card: some words are replaced by the following characters ●●●●●●●. These characters will appear both in the preview, and in the output document.
Prizmo keeps asking me to connect to the Internet in order to register. I checked my connection several times. What am I doing wrong?
Internet connection is established when you first activate the application. This problem usually occurs when you type something wrong in the activation code (e.g. problem with the case, missing number or letter or an additional blank after the code). Try again to copy and paste your activation code because it is case sensitive.
Entering the activation code did not activate Prizmo. I tried downloading a fresh copy, but this did not help. When I restart I get the message that Prizmo is not registered.
Please try again. As the activation code is case sensitive, it is usually better to copy/paste it. Please be careful not to enter leading or trailing spaces.
Mac App Store Version
I purchased Prizmo on the Mac App Store but didn't receive any serial. Can you send one to me?
Apple relies on another licensing system for activating applications available on the Mac App Store. You don't need any code to register it. After purchasing an application, it is fully functional right away. Moreover, the purchase is saved in your iTunes account history. It means that if you want to install Prizmo on your new Mac, you only have to download a fresh copy from the Mac App Store (and you won't be charged a second time by the way).

What is the difference between Prizmo sold on the Mac App Store, and Prizmo sold through Creaceed's website?
First, the licensing system: you need a serial for registering applications sold through Creaceed's website, but you don't need one if it was downloaded from the Mac App Store (Apple relies on another licensing system). Besides, the major difference is that only the Mac App Store version of Prizmo supports iCloud.
How can I make sure I already own Prizmo 2 with the Pro Pack?
Open Prizmo's Preferences, and click the Pro Pack tab. You can check there if the Pro Pack is activated or not.
Is Prizmo compatible with Snow Leopard (OS X 10.6)?
No, it isn't. Prizmo relies on some technologies only available in Lion and Mountain Lion. It would be very difficult and time-consuming to develop exactly the same application compatible with previous versions of OS X. And the output images wouldn't be as good as they are under Lion or Mountain Lion.
Do you plan to release Prizmo for Windows?
Creaceed is specialized in Mac and iPhone development. We started over 10 years ago to work with all Mac-related technologies (Cocoa, Objective-C, OpenGL...), and we think they are great. So, we want to go on this way. We have no plan for a Windows version at this time.
Which scanners are supported?
A list of supported scanners is available on Apple's website. The word "Scan" is mentioned next to all scanners which are supported by OS X.
Is there anything I can do to check my scanner is supported before purchasing a license?
Yes, there is.
Open the Preview application. Click File, and then Import from Scanner. If your device is listed there, it is supported by OS X.
And don't forget Prizmo's trial version is fully functional. So, you can also check if your scanner is supported by importing a document into Prizmo right from your device.
Do you have a list of cameras supporting full tethering?
We rely on the tethering function as implemented in OS X, and Apple does not provide an official list of supported devices. However, we think that Nikon and Canon DSLRs are a safe bet.
Can I perform OCR on screenshots?
Yes, you can. Prizmo automatically detects you imported a screenshot, and applies a specific processing in order to increase the screenshot resolution, and therefore its readability. As a result, OCR should be nearly as accurate on a screenshot as on a page coming from a scanner.
Besides, you can perform OCR on text visible on your screen even without making a screenshot! Click the prism icon in the status bar (upper right corner of your screen), draw a rectangle around the text to select it, select the language and click the Copy Text button. The text is copied to the clipboard, and you can paste it wherever you want.
Can I automate the actions so that many book page pictures are processed in a similar fashion?
Yes, you can. Put your DSLR on a tripod, connect it to your Mac, and keep the book in the same position when you take pictures. You'll be able to use full tethering, and therefore to take pictures right from within Prizmo, without even touching your camera!
Selection and Preview
I imported a photograph into Prizmo but it is upside down. How can I correct that?
You can rotate the input photograph without any problem in Prizmo. Click the Left or Right button in the bottom toolbar.
I am trying to move the grid corners to fit the page corners, but the grid remains a rectangle. What can I do to change it into a parallelogram?
Perspective is currently locked in the document. You can resize the grid, but you can't correct perspective indeed. To fix this, open the Crop window, and click the Frame tab. Click the icon showing a document viewed in perspective (next to the Auto Detect button), and it will enable freeform frame reshaping. Alternatively, you can hold the Command key while dragging one of the frame handles.
This UI detail states that perspective is locked.
How can I position the grid accurately in the Crop window?
In the lower right corner, you can move a slider to set the zoom level applied on the previewed picture. Besides, there are several zoom options available in the View menu:
Zoom in or Command and + keys
Zoom out or Command and - keys
Zoom to Selection or Command and * keys: zoom is applied to preview only the selected region.
Zoom to Actual Size or Command and 0 keys: zoom is applied to preview the input picture at 100% (the previewed image might be really big as a consequence).
Zoom All or Command and 9 keys: zoom is applied to preview the whole input photograph (the previewed image might be small as a consequence).
Moreover, you can move the previewed picture within Prizmo: click the picture, press the Alt key and move until the picture is where you want it to be.
How can I change the preview format?
You can change it in a very accurate way in the Dimensions window. Choose a standard preset like US Letter or opt for a custom format. For the latter, you can type a number in the fields "Width" and "Height". Besides, you can choose the preferred unit in Prizmo's Preferences (pixel, inch, centimeter or millimeter).
Is it possible to use Prizmo for correcting distortion on panoramic images made of several shots?
Prizmo’s purpose is to correct the distortion of a single image using the data coming from camera calibration. And Prizmo’s calibration assistant is for standard camera images only.
Is it possible to process several images in a single document?
Yes, it is but document type must be the same. It means that all input images must be either business cards, or text documents, or regular images in a single Prizmo document. If you need to process several text documents and an image, you'll have to create a Prizmo document for the text documents on the one hand, and another Prizmo document for the image on the other hand.
Optical Character Recognition (OCR)
You announce 40 languages for OCR, but there are only 10 available in Prizmo.
There are indeed 10 built-in languages in Prizmo (English, German, French, Italian...). It means you can perform OCR in these languages as soon as Prizmo is installed. The 30 additional languages (Russian, Finnish, Korean...) need to be downloaded first. Don't worry, you don't have to download all these languages if you only need one of them. Open Prizmo's Preferences, and click the OCR tab. Select the OCR language to be downloaded in the list. The language is available in Prizmo as soon as the download is complete (no need to restart Prizmo).
How to Improve OCR Accuracy?
Here is a tip to get better OCR results: before performing OCR, move the readability slider in the OCR window, and check if you can read the text previewed in Prizmo. This feature shows you exactly what the OCR engine gets as input when it launches. If the input is good (i.e. if the text is neither too bright nor too dark), recognized text will be highly accurate.
I tried Prizmo's OCR but I got poor results. What can I do?
We checked the accuracy of the OCR engine in the 40 available languages. Even with pictures taken in poor circumstances (document on several other documents, picture taken in front of the document rather than above...), we got very good results.
Here are some recommendations for improved OCR results:
you should be right above the document you want to photograph.
use the camera flash when you take a picture.
when you select the text, check the grid is larger than the text to be recognized.
make sure the top and bottom lines of the grid are parallel to the text to be recognized.
choose the language of the document in the list (you can recognize a letter in Spanish while using Prizmo in English).
zoom in to get the text regions in close-up, and play with the Readability slider. You should be able to read the text on the whole page.
Is the quality of my images good enough to perform OCR?
Image quality is a major issue indeed. OCR results will most likely be disappointing if the input image quality is poor. Here are a few examples of what should be avoided:
The image is blurry. Check you are able to read the text on the picture. You can't in this example. Please take a new picture of better quality.
The ticket is crumbled.
It is a double-sided document. Characters, lines and colors which are printed on the other side could hinder OCR.
How to perform OCR on multipage documents?
Prizmo 2 is able to perform OCR on multipage documents, and export the whole recognized text in a single document. After importing the document into Prizmo, select all pages in the left column, choose the OCR language, check the text readability, and click the Recognize button. You can preview the OCR results for each page individually by selecting the related page in the left column. When ready, click the Export button. You can output either all pages, or only the selected page(s).
Which file types are available for saving OCR results?
Besides the usual image files (jpeg, tiff and png), there are several text files available:
PDF: text is formatted (columns, character size, bold, italic...), and it creates a new clean document.
PDF (Image + Searchable Text): it is made of formatted text (columns, character size, bold, italic...) in addition to an image of the input document. Recognized text is Spotlight-indexable. It's the best file type for archiving purposes.
Rich Text or RTF: text is partially formatted (only bold, italic...). Very handy if you want to copy/paste text in Pages, Mail, OpenOffice...
Regular Text or TXT: it's raw text without any formatting. For people who want to modify the lay-out of an existing text.
How do I install custom scripts?
You can download and install these sample scripts by clicking here. Install the package by double-clicking it.
This installs scripts in your $HOME/Library/Application Scripts/ folder.
If you got Prizmo from the Mac App Store, the scripts will be in the com.creaceed.mas.prizmo2 subfolder.
If you got Prizmo from our store, the scripts are located in the com.creaceed.prizmo2 subfolder.
All the scripts you make must be located in this specific subfolder.
This subfolder contains 2 scripts (one AppleScript, one shell script). You'll notice that these scripts also appear in Prizmo Preferences > Export Options > Script, where you can select them. Once selected, the script is invoked when you export your document with the script option.
Please refer to the provided sample scripts to see how arguments are passed (this depends on whether the script is a shell script or an AppleScript).
Calibrating your Camera
Is camera calibration mandatory?
No, it isn't. Before calibrating your camera, check if a calibration model is already available on Creaceed's servers. Many users have already shared their calibration results to Prizmo's database, and they are available to all Prizmo users.
Import your picture into Prizmo, open the Lens window, and check the "Lens Correction" box.
A model is available: several calibration models are listed in the drop-down menu. Besides, some information about your camera, lens and zoom is mentioned in the window header. Great! You don't actually need to calibrate your camera (but you can if you really want to).
No model is available: a pop-up window warns that no model is available ("Optics not found"), and asks you either to use Prizmo without correcting lens distortion, or to calibrate your camera. We advise you to take a few minutes for calibrating your camera as it will help Prizmo correct lens distortion more efficiently. You can notice lens distortion on objects near picture's sides. For instance: a wall or a tree will look like curved, rather than straight.
Prizmo rejects the pictures of the pattern I shot with my camera. Why?
It seems that Prizmo didn't manage to locate the pattern on the pictures. There are several rules to follow when you take pictures of the pattern if you want to create a reliable calibration model.
the pattern should be as big as possible (taking a picture of the pattern at 6 feet from the flat screen is useless)
the whole pattern should be on the picture with some white space all around
you should take pictures from different points of view.
This picture was accepted when calibrating the camera
I calibrated my camera but I can’t find any calibration model in Prizmo. Should I calibrate once again?
Basically, you have to calibrate each camera body + lens + focal. Once calibrated, you can import a picture with the same attributes, and Prizmo will automatically select the related calibration model. You can see which model is being used in the Lens window.
If there's no calibration model available in the Lens window,
either none of your calibrations (camera body + lens + focal) can be used for the imported picture
or the picture you imported misses some EXIF info (this can happen with older lenses).
Remark: Be careful with varying focal lenses, like a 16-35 mm: if you calibrate the 16 mm focal, it will work only with 16 mm photographs. If you set the zoom to 20 mm instead, the calibration won't fit. You’ll have to calibrate camera body + lens + 20 mm focal as well.
