Vdraw A SHAREWARE drawing program by Stephen Vermeulen Copyright (C) 1987 by Stephen Vermeulen ======================= Copyright Statement ======================== The program: "Vdraw 1.19" is Copyright (c) 1987 by Stephen Vermeulen. The author reserves all rights to this program. The author grants private owners of Commodore Amigas the right to copy this program and use it for their own private purposes. Permission to use this program by any Government, or any agency thereof (including any group that receives financial support from any government), or for any commercial use is not granted. To obtain permission for governmental or commercial use write the author at the address below and include the number of machines you will be using Vdraw on, and the frequency of updates you want. This is a public domain screen drawing program, you may copy it without guilt but if you use it much, and especially if you want it to improve, please send me US$20.00 (CDN$20.00 in CANADA only) and I will register you as a user and send you a copy of the Vdraw manual. My name and address is: Stephen Vermeulen 3635 Utah Dr., N.W., Calgary, Alberta, CANADA, T2N 4A6 My phone number is: (403) - 282 - 7990 ===================== Program Update Policy =========================== NOTE: the following prices are in U.S. DOLLARS, unless you live in Canada, then you can read them as Canadian dollars. As I work on improving Vdraw quite a lot (the version number increases by 0.01 about every 2 weeks) I have established the following update policy. Send me $7.00 for every update you wish to receive and a list of version numbers you want to receive and as the version numbers become available I will send you new Vdraw disks. If you want to reduce this cost, send me a disk with your name/address and version desired on the label and $3.00 instead. For example you might want to receive four updates with about two months between each update. To do this send me a check for $28.00 and ask for the following Vdraw versions (assuming 1.09 is the current version) 1.13, 1.17, 1.21, and 1.25. Or else, send me 4 disks with name/address/version information on the labels and a check for $12.00. You could also include a note as to how much upgrading you wish to see in the new version, for example "wait for a major new feature like "line", "when you have done 30 hours of changes", etc. NOTE: you do not have to be a registered user to ask for updates, however my hearing is considerably better when a registered user asks for a new feature or change. =============== Need a new feature or found a BUG ? ================== Write me! Write me! Write me! Remember though, I seem to be able to understand a REGISTERED users' comments much better (faster). ======================================================================= ----------------------- Release 1.19 Notes -------------------------- This release is the first to feature the new, entirely ICON driven, user interface. Since this required such a major rewrite of the program there may be new and unexpected bugs. There are some new features and some of the old features have not been added yet (see 1.20) ... NOTE: Vdraw 1.16 was the last to feature the menu style user interface, Vdraw 1.17 and 1.18 were released to a few of the Registered Vdraw Users who were interested in having the new icon interface as soon as possible. -------------------------- Using Vdraw ------------------------------- Using Vdraw, the bottom row of icons selects the major tools. When you have selected a major tool the tool's icon will be highlighted and a new panel of modes for this tool will appear on the right hand side of the display, you use these mode icons to select the features of the tool you want to use. The major tools are (from left to right): 1. Line mode - Sketching - Straight lines - Horizontal / Vertical lines - and various line styles - ... the arrow head feature is not installed yet ... 2. Box mode - Hollow boxes - Solid boxes - Patterned boxes ... not installed yet ... - Invert an area. 3. Curve mode - Circles - Circular arcs, hold down the CTRL, left SHIFT, and left ALT keys to adjust parameters. CTRL and mouse moves adjusts one end point of the arc. LEFT ALT and mouse movements adjusts the other end point of the arc. LEFT SHIFT and mouse movements adjusts the radius of the arc. - Single control point Bezier curve, click on the first end point and then on the second end point, adjust the shape by moving the mouse, when you are satisfied click again. - Dual control point Bezier curve, click on the end point locations, then move the mouse while holding down either the LEFT SHIFT or the LEFT ALT keys. This adjusts the points which control the slopes at the end points. Finally click the select button when you are satisfied. - The + and wedge icons select modes for the drawing of circles and circular arcs. - note: to get circular circles on the printer you will have to set the aspect ratio parameter in the vdraw.profile file. See the profile section. 4. Spray Paint - While you hold the select button down and move the mouse you spray paint in the current pen colour. - To adjust the spray slide the R and D gadgets, the R gadget adjusts the radius of spray and the D gadget adjusts the density of spray. 5. Brush mode - first make some cuts in the cut mode, then ... - This allows you to brush with an area you have cut from the drawing surface, or a cut you have loaded. - You click on the two arrow icons to select the brush you want to use. - The brush and paste icons indicate whether you are in continuous brush mode or in single copy paste mode, click on these to select the mode. - There is a slight bug in this one, the very first time you release the select button after brushing the area under the brush will be incorrectly restored. - Note, this mode will ignore any clicking of the CloseWindow gadget, this is to prevent memory deallocation problems. 6. Fill mode - not installed yet ... This mode will allow you to fill in one of several predefined fill patterns (which you can customize), or to use any of the cuts as a fill pattern. 7. Magnify mode - Upon entry yo this mode the screen is redrawn at an 8 fold magnification. The area that is magnified is the top left corner of the current window. - You can scroll the view with the arrow keys. - You do single pixel editing in this mode by clicking on the pixel you wish to set to the current pen colour. 8. Text mode - Click in the text requester at the bottom of the screen, hit return, and then when you hold the select button down you will drag the text around the screen. - Change the text style with the underline, boldface, italics, and extended mode icons. - Change the text drawing mode with the 1, 2, complement, and reverse video mode icons. - When you are satisfied hit the OK icon, otherwise hit the QUIT icon. - A known bug in this one is that upon exiting from text mode the highlighting of the currently selected major tool becomes brain damaged, this is not dangerous, but it is anoying ... 9. Font mode - Use this mode to select the font you wish to use for text typing. Note: if the system cannot load the font (because of memory problems) a message will be printed in the DOS window. The EMERALD fonts are particularly large. 10. Lock mode - Use this mode to lock areas to prevent them from being permanantly damaged. - box the area in the drawing you wish to backup, then hit the closed lock icon. - you can then lock another area following this procedure. - the arrow buttons will show you what areas are currently locked. - to restore an area that was locked and then damaged by some editing just select that lock with the arrows and then hit the open lock icon - to restore all locked areas hit the "many shackles" icon - to discard a locked area you do not want to restore any more, select it with the arrows and then hit the trashcan icon. 11. Cut mode - use this mode to cut areas from the drawing surface for use as brushes or to selectively save. - The arrow icons step you through the list of cuts. - The trashcan is used to discard any cuts you do not want anymore. - The currently displayed cut may be saved to disk using the TO DISK icon. - A file may be loaded from disk into a cut using the FROM DISK icon. - The number of cuts is only limited by available memory. - Note: the cutting process makes the currently selected Background Pen the transparent colour in the cut. 12. Fx mode - this mode, when implemented, will allow you to do all sorts of neat things with the various cuts that you have on hand, rotates, mirroring, stretching, distorting, shearing ... 13. Erase mode - hit ALL to erase everything to the background colour - or just box areas you want to erase. 14. Palette mixer - Select the colour to be adjusted with the drawing pen icon and the colour palette across the top of the screen - remix the colour with the sliders. - the bug in this one is that Intuitions AUTOKNOB does not show up until you turn borders off, but you still get borders ... Not dangerous but an anoyance. 15. nothing yet 16. Print mode - This mode allows you all sorts of flexibility with printing - The BOX icon tells the printer routine to print only a boxed area. The default area is the current window view, however, you can just box any area and then that area will be printed. - The ALL icon tells the printer routine to print the full bitmap. - The AS icon tells the printer routine to AUTOSIZE the printing. This mode makes the printed output have the save aspect ratio as the screen displays. When this mode is on, the scaling factors are ignored. - The MULTIPAGE icon (the one with three overlapping boxes) is used if you want the output to appear as a number of pages that you cut and paste togeather. Note: this mode works best if you have a bitmap that is the same size as the printers page. - The scaling icons (1x, ... 5x, 1y, ... 5y) select the expansion factor for the X and Y directions to be applied to the bitmap. This allows you to use a bitmap that is (say) 1/4 the area of the full size printer's page and have a full page printout without any distortion of line thicknesses. - Once you are satisfed, press the print icon. 17. Disk mode - this allows you to do loading and saving of pictures and portions of pictures. - The BOX icon tells the save routine to save only the boxed area, and tells the load routine to restrict the loading to only the boxed area. - To set a boxed area just click in the main window and box the area desired. - The ALL icon tells the load and save routines to use up to the entire bitmap. - The P icon tells the save routine to save the data in packed format (less disk space used) - The U icon tells the save routine to save the data in an unpacked format. - The CM icon tells the save routine to save the screens ColourMap along with the routine, it tells the load routine to use any ColourMap data in the image file. - The NOT CM (CM with the line over top) icon tells the save routine not to save a colour map, and tells the load routine to ignore any colour map data that may be in the file. 18. Graphics mode - not implemented yet ... Possible features here include changing screen modes while in Vdraw. -------------------------- Vdraw Profile ------------------------------ There is a file called "vdraw.profile" that should be in the Vdraw: directory. This file contains several parameters that can be used to customize Vdraw to your particular requirements. A typical file might be: 1000 400 250 4 7 -11 100000 320 200 A line by line explaination follows, 1000 This number is the aspect ratio multiplied by 1000. 1000 means the pixel's height is the same size as the pixel's width. To make circles circular on a printer (Epson driver) where there are 120 dots per inch horizontally and 72 dots per inch vertically you calculate the value thus: 72 --- * 1000 = 600 120 400 This is the width of the super bit map. You can make this quite large (say 1000), possibly the best thing to do is to make this the same as the number of horizontal pixels your printer prints. (The Epson driver seems to do 120 pixels per inch, so I use 960) 250 This is the height of the super bit map, for an 11 inch page on an Epson I use 720. 4 This is the number of bit planes to use, this sets the number of colours you get. Currently, this can be 1, 2, 3, 4, or 5. Note that if you use a 640 wide screen this can only be 1, 2, 3, or 4. 7 -11 These will be used for arrowheads when they are implemented. 100000 This is the refresh rate of the zoom lens that comes on in the lower right hand corner of the display when the menu button is pressed. This is the number of micro seconds between refreshes of the display. 320 This is the width of the screen to use, this is normally either 320 or 640, however, you can specify other values if you have a monitor that can display the overscan area. But, if you specify some non standard value you must realize that intuition only allows you to move the mouse to position 319 or 639. 200 This is the height of the screen to use. This is normally either 200 or 400 for North American systems, if you live in Europe you can probably use 256 or 512, this has NOT been checked, let me know if it works! Again, you can use non-standard values if you want to squeeze a bit more onto the screen. ------------------------- Extra Credits ---------------------------- Let me express my thanks to Charlie Heath at MicroSmiths Inc. for putting his file name requester (that I am using) into the public domain.
