I have image with charset (for example like in uploaded image), and file with data (coordinates of every letter or symbol). How can I use it for writing text? What DarkGDK commands I need to use for this? Maybe, some code?.. Thanks!

Dark Invaders tutorial that comes with DarkGDK has an example of using sprite text (exactly like your case)

No, Dark Invaders uses sprite for EVERY letter. I have big pieces of text, and so it will be hundreds of sprites. Maybe it will be too long.
Other ideas?

Maybe you can break it up into one image per letter (with dbGetImage) and then use dbPasteImage to put the letter images onto the screen.

EDIT: Breaking up is necessary because dbPasteImage does not have area parameters to copy only part of an image.

To be even clearer, you would load the image as a bitmap (dbLoadBitmap), then dbSetCurrentBitmap to the loaded image, then dbGetImage in a loop until you get image numbers for all letters. Then the original image is no longer needed and you can use dbPasteImage with the numbers of the separated letter images. (You probably need to set the current bitmap back to the screen - zero - after the images are done.)

Thanks, Mireben, it is a good decision for me.
