| | Bit blit - Wikipedia, the free encyclopedia |
 | | Bit blit (bitblt, blitting etc.) is a computer graphics operation in which two bitmap patterns are combined into one using a RasterOp. | | | The name derives from the BitBLT machine instruction for the Xerox Alto computer, standing for "Bit Block Transfer". |

| | BitBlt |
| | The name BitBlt is derived from a powerful bit-boundary block transfer instruction of that name found on one of the first machines to support Smalltalk, the Xerox Alto. | | | As a result, it was decided to use instances of a class (BitBlt) rather than a method to represent copy operations. | | | RasterOp is a synonym for BitBlt in many graphics systems. |

| | The BitBlt API call was the first API I learned how to implement, as I suspect may be the case with many who may come across this tutorial. | | | This tutorial is a revised version of the original BitBlt API primer/tutorial I originally wrote in May, 1998. | | | BitBlt allows you to transfer those pixels to your destination in a number of different ways. |

| | This will probably be my last resort (bitblt'ing the text), but, it seems like it would be the most efficient since i use the bitblt function several times in my program. | | | The reason why it has to be a picturebox, and not an image, is because i am having to use the BitBlt function (-so..i need to use a picturebox).. | | | The only other way I know to help is to just have you post your project as an attachment and I would add the textout code and I would modify the project to add the textout and re-upload it when I get home tonight (late). |

| | Visual Basic Explorer- Games, Animation & Drawing |
| | When we are drawing an image from one Device Context to another, BitBlt is actually copying the value of each pixel in the source picture, and performs a specified Raster Operation on the destination with this copied value. | | | Though some API calls are more difficult to use and may contain some scary syntax, judicious use of API's can enhance the functionality and features you can add to your programs and are sometimes the only way to do what needs to be done. | | | You can still use BitBlt even if you don't understand all the specifics of Boolean math -just like you can drive a car without understanding how everything in a car's engine works. |

| | A device context, according to Nigel Thompson in Animation Techniques in WIN32, is a structure that defines a set of graphic objects and their associated attributes, and the graphic modes that affect output. | | | Handle - This is the handle to the actual memory device context used for the BitmapBuffer object. | | | The first list of options are the ROP Codes used for subsequent BitBlt's. |

| | If the color formats of the source and destination device contexts do not match, the BitBlt function converts the source color format to match the destination format. | | | For more information, see the RC_BITBLT raster capability entry in the GetDeviceCaps function, as well as the MaskBlt and StretchBlt functions. | | | If a rotation or shear transformation is in effect in the source device context, BitBlt returns an error. |
