One pixel in the x-axis represents 2 pixels in screen size.Īlso, one cell can only contain the maximum of 4 colors, including the background. It contains 4 pixels you can draw in the x-axis and then 8 pixels you can draw in the y-axis. Where each of the cells contains 4×8 pixels (8×8 in real): I also mentioned that this image mode splits the image into 40×25 attribute cells: Notice that the width of one pixel spans across two pixels when rendered. In this picture, I drew ONE line across 8 pixels, and another line down 8 pixels. where one pixel in the image represents 2×1 pixels in screen size:
Each is also limited to contain the maximum of 4 colors. Another important attribute with this mode is that the screen is divided into 40×25 attribute cells, where each attribute cell is 4×8 pixels in size. One pixel in the image represents 2×1 pixels when rendered on the screen. As you can see, the resolution of the images is smaller than the screen. The format we are implementing is named MultiColor and got a resolution of 160×200 pixels, with the support of 16 colors. The one introduced here is a pretty common one and will work as a basis to understand the rest of them. The Commodore 64 supports a few different graphic modes. When painting for the Commodore 64 you must be aware of a few limitations. Load Timanthes and you will see an environment much similar to other painting programs in front of you. The tool I like to use is named Timanthes v3, and can be downloaded below.ĭownload Timanthes 3.0 beta by Mirage of Focus: Next we will load the image we created into our own program and render it.īefore you can draw your bitmap, you will need a tool. First we will look at one way of creating bitmaps/images for our C-64 programs by using a tool for Windows. In this tutorial we are going to cover two things. Update: All needed files for this tutorial can be found in the GitHub repo linked in the bottom of this page.
