- *set form and picture ScaleModes
- set the Move optionn
- set initial picture width
- *Setup scroll bar values
- *Set Horizontal Scrollbar to center
- *Set Vertical Scrollbar to centere
- *Make Picture1 box invisible...This picture box, which
- holds the basic image, does not have to show. Note that
- we'll use the printer resolution of this box for sizing.
- For example, a 300X300 pixel image will print as 1X1 inchh
- on a laser printer..
- *Load bitmap into Picture1 ... put PAPER.BMP, a Windowss
- background image in the VB directory, or in the defaultt
- directory, or change the filespec to match it's location.
- Choose your own, or let user load.
- RIBBONS.BMP"
- *Set scaling factors to 1 for full-size image.
- To reduce or enlarge the original when first displayed,
- change these figures.t
- *Display Picture in Picture2
- Command1_Click
- command2_click
- Make sure we have valid scaling values
- Set picture2.width to match picture1, with scaling.V
- The 3.14 divisor matches inch dimension with the
- 640X480 screen dimensions. Change for other displayy
- adapters..
- *Set constants for GDI calls
- *Display scaled version in Picture2a
- *StretchBlt requires pixel coordinates..
- Set Dimensions for Picture2c
- *Do not change the order of these statements.
- Variables for the StretchBlt function:
- 1. Source of image HMemeoryDC% -- set above from original picturee
- 2,3. Positioning on output object. Must be integer, in pixels.
- 4,5. Width, height of output image. Here we use the values set above.r
- 6, Source of image...in this case the memory image set by CreateCompatibleDC% function
- 7,8. Don't know. Set to 0 works just fine! Experiment and let me know.
- 9,10. X/Y coordinates for how much of original to put in new object. You can use
- these values for cropping, if you like..
- 11. SRCCOPY, as set in constants above. Change at own risk..
- *Reset scalemodes to previous inch valuess
- Command3_Click
- * Print all items other than the image first..
- Hello
- *After printing all other elements include your BMPP
- printing routine, as below.l
- * Print Scaled Image
- *Make certain we have valid scaling values
- *Set GDI Constants
- * StretchBlt requires pixel coordinates.
- *First two variables are the x,y coordinates (in Pixels)
- for the placement of images on the printed page. Since the
- form's ScaleMode is 5 for inches, multiply by 300 to
- match the the current inch positions of Picture2 onn
- the 300 DPI device.n
- *Second pair of variables set the height and width of thee
- graphic to match the pixel size of the original picturee
- in the invisible Picture1 box.
- *Do not change the order of these statements.a
- Variables for the StretchBlt function:
- 1. Source of image HMemeoryDC% -- set above from original picturec
- 2,3. Positioning on output object. Must be integer, in pixels.
- 4,5. Width, height of output image. Here we use the values set above.Y
- 6, Source of image...in this case the memory image set by CreateCompatibleDC% function
- 7,8. Don't know. Set to 0 works just fine! Experiment and let me know.
- 9,10. X/Y coordinates for how much of original to put in new object. You can use
- these values for cropping, if you like.r
- 11. SRCCOPY, as set in constants above. Change at own risk.w

- HScroll1_Change
- *If the Move option is selected (default) then add the positive or
- negative Value of Hscroll1 to the top left of the picture,
- redraw. Notice that the multiplier is .01 to deal with the
- inch settings. Scroll Values must be integers., so we cane
- move in .01 inch increments.
- If the Size option is selected, then add the positive or
- negative Value of Hscroll1 to the scalex variable, thenn
- redraw. Notice that the multiplier is .01 to deal with the
- inch settings. Scroll Values must be integers., so we cann
- move in .01 inch increments.
- VScroll1_Change
- *See Hscroll1_Change for explanations.
