I wrote this to allow me to transfer full Command-Shift-3 MacPaint Documents to MacWrite and MacDraw, via the Clipboard. Also I allow the user to make a selection of part of the full 512 by 342 bitmap, many times too large for MacPaint. To make room for the full bitmap, I don't use menus, so the keyboard commands shown on the startup screen are important to note, also, typing 'H', 'h' or '?' will redraw the startup screen at any time.
JoyPaint 1.2 John Stogdell Stokes III - CompuServ 74226,2660 August 1985
============
JoyPaint will run on both 128k and 512k Macintoshes as well as under a 128k Switcher region on a 512k Macintosh.
JoyPaint is a stand alone application that displays MacPaint drawings and gives you the means for srolling MacPaint drawings in any direction by using a simulated JoyStick. The operation of the JoyStick is meant to be intuitive. Open up a MacPaint drawing and then click in the JoyStick window. The cursor will change shape when you release the mouse and scrolling will start. Move the cursor around in the JoyStick window to experience the different directions and rates of speed. Move to the bottom of the JoyStick window to see the bottom of the MacPaint drawing. Clicking the mouse immediately stops scrolling.
MacPaint drawings are read using the standard Mac interface. The MacPaint drawings may be flipped horizontally and/or vertically and may be inverted. The whole MacPaint drawing page (8 by 10 inches, not just the screen) is affected. The MacPaint drawings may be saved. The 'New' menu key provides a means of creating a new MacPaint drawing. By selecting the 'Invert' key from the 'Modify' menu, you can create a MacPaint drawing that is initially black.
JoyPaint does not support the clipboard. If you need it, install JoyPaint and MacPaint or any of the other MacPaint compatable programs that support the clipboard under Switcher. You can then open up a drawing under MacPaint, modify it, close it, switch to JoyPaint, open it, modify it, close it and go back to MacPaint.
Scrolling is an interesting subject and some fun can be had with JoyPaint. The Mac desk accessories are accessible. After opening several desk accessory windows and moving them on top of JoyPaint's MacPaint drawing window, go to the JoyStick and scroll the MacPaint drawing. The MacPaint drawing scrolls underneath the Desk Acessory windows. By covering up parts of the JoyPaint window, variation in scrolling speed results. If a narrow rectangular strip shows, scrolling is extremely fast and smooth. If a large jagged shape is showing, then scrolling is slower and less smooth.
If you scroll the drawing vertically at the start, scrolling is very smooth. But if you scroll to the side and then scroll vertically, scolling will be slower - this is because, at the start, both the drawing and the window are at the same "Mod 16" with respect to the horizontal coordinate of the screen. Shifting the drawing causes a difference to occur. When this happens, redrawing the screen takes more processing.

The purpose of the PainToR program is to allow the use of applications like MacPaint and MacDraw to design the graphic images which are to be used within a program. PainToR displays the PICT resource type images saved in the Scrapbook file and optionally saves each image in a form that can be compiled by the Resource Maker (RMaker) utility. The graphic image can then be read as a Bit Map and displayed via Quickdraw's CopyBits routine.
The Scrapbook pictures are saved to a text file (creator = EDIT, type = TEXT) in hexadecimal form with a resource type = BITS. The rowBytes, width and length (in bits) fields are also saved. This makes it very simple to read the resource in a form that is easily converted to a BitMap. The only field that needs to be set is the baseAddr field. Since this field points to the start of the data there is no way that it could be saved as part of the resource. The file created can be edited using the MDS EDIT utility or any other file editor. The resource type can be changed to any resource whose data is defined in hexadecimal form (e.g. ICON, ICN#, etc).
When using MacPaint to design an image, the image should be cut using the lasso or the selection box and then placed in the Scrapbook. If you want to design an image of a specific size then a frame which perfectly surrounds the image can be first created. PainToR has an option to save only the image inside the frame. For example, if you are creating an ICON using MacPaint, then you want the ICON to be exactly 32x32 bits in size. First Create a 34x34 box which will perfectly surround the ICON. Next, you can create the ICON inside the box or place it inside if it is already created.
When you run the PainToR program you should specify that the image be saved without the frame. This will ensure that the image is saved with exactly 32x32 dimensions. Your will need to edit the resource file and change the resource type from BITS to ICON. Also, ICON resource only include the data so the dimensions should also be deleted.
An example (in C) of reading a BITS resource and converting it to a BitMap follows:
