Kronocard Photo Import

Just a few weeks ago we added to Kronocard a photo import module. Now is the time to introduce it. I must admit it's pretty impressive. In fact words fail me and I'll let speak this animation:

Click to see in full screen!

Wow! What we have here? A package of exciting features :)

  • The top section allows you to choose which photo file you want to import and there is an preview at the right. But as seen in the animation when the selected photo is imported the software automatically selects the next photo file so it is ready to be imported too.

  • When a picture is imported software automatically detects corners and performs deskew. Of course if ever the software is wrong simply move the red targets.

  • A zoom button allows you to preview the resulting images

3 supported modes

  • Import individual cards photos
  • Import photos of set of cards
  • Import existing scans of individual cards

In each mode you have to provide 2 pictures for each card or set.
Pictures to import must be in jpeg format.

Import individual cards photos

Select this first mode to import pictures of individual cards taken from a camera, cell phone or tablet. You will need a picture of both the front and the back.

The import individual cards photos mode automatically warp pictures to correct perspective effects.

Kronoscan will attempt to dectect the corners of the card automatically. Success rate will be much higher if your card stands on a surface of uniform color that contrast with the card border color.
A grading case is easy to detect over a dark background.

If the corner detection fails then manually move the red targets over the corners of the card: You just have to click on a target and maintain the mouse button pressed. Release the mouse button to confirm the new target position.

Import photos of set of cards

This second mode is intended for selling a set of cards in one transaction. You must specify the quantity of cards in the set. To retain the compatibility with our existing tools you must provide exactly two pictures of the same set.

There is no automatic cropping for pictures of sets. However manual cropping is available by moving the red targets with the mouse.

Import existing scans of individual cards

This third and last mode is intended to import existing scans of individual cards. Front and back scans are required.

Usually buyers like to see the card borders. However it is possible that your existing scans do no include an external border.
When this is the case, use the borderless option. When that option is selected Kronoscan will not attempt to automatically identify the card corners to redo the cropping.

Approximative card(s) size

You must specify the appriximative cards size because:

  • It corrects the aspect ratio errors caused by the perspective for individual pictures of cards
  • It defines the final size of the image in Kronocard
  • The size of cards is an information shown to buyers on and
