<p>When displaying screen image, the default pointer is <a class="el" href="group__ScreenGroup.html#ga9c8a0032cf1145c5a6c369193a134a78">pScreen</a> for the library. It points to the <a class="el" href="structsScreen.html" title="Video screen (on change update SSCREEN_* in define.h)">sScreen</a> structure that describes the contents of the display. The Raspberry Pico has a limited RAM size and cannot accommodate a high resolution image. Therefore, the image must be composed of smaller segments to minimize the memory-intensive parts. </p><dl class="section note"><dt>Note</dt><dd>The following descriptions of the image format only apply to the base image layer 0. It is the only one that can contain segments in different formats. Overlay layers 1 through 3 are independent of the base layer format, sharing only the total screen area with the base layer but using their own image format. </dd></dl>

<p>Set video segment to tiles. </p>

<p>Tiles in column (GF_TILE). Tiles are image segments of the specified size (tile width and height are 'w' and 'h'). The tile patterns are arranged in a single image. In this case, into a column of width 1 tile. The 'tiles' parameter is a pointer to the image of the tile column. The 'data' parameter is a pointer to an array of bytes, where each byte represents number of displayed tile. Thus, there can be a maximum of 256 tiles. The 'wb' parameter refers to the length of the row of the index array (not the length of the tile image). The width of a tile must be a multiple of 4, at least 8. Tiles allow efficient display of image information by allowing the image to repeat. Thus, high image resolution can be achieved with low memory requirements. </p><dl class="params"><dt>Parameters</dt><dd>

<p>Level display segment (GF_LEVEL). This segment is used to display graphs. The input is an array of 'data' bytes of length corresponding to the width of the array in pixels. The byte value represents the height of the graph at the given X coordinate. The display will show a foreground or background color depending on whether the displayed pixel lies above or below the value from the data array. The 'zero' parameter specifies the height of the reference zero. Zero does not imply negative numbers in the data, the numbers are still given as unsigned (with zero at the bottom). Starting from reference zero, the background and foreground colour is swapped. This results in the graph looking visually symmetrical around the reference zero. You can see the appearance of the segment in the Oscilloscope sample program (lower curve). </p><dl class="params"><dt>Parameters</dt><dd>

<p>2-bit palette graphics 4 colors in 2 planes (GF_PLANE2). The mode is functionally similar to the 2-bit color graphics mode, but the individual pixel bits are stored in 2 separate color planes. This mode is similar to the CGA graphics mode of PC computers. The individual planes correspond to two separate monochrome graphics modes. Each byte of the plane contains 8 pixels (the first pixel in the highest bit). The parameter 'plane' is the relative offset of the second plane from the first plane, given by the parameter 'data'. The function requires a palette translation table, which is generated by the <a class="el" href="group__ScreenGroup.html#ga415f2e80d3d6e92cb026401cba09331f" title="Generate palette 4-color translation table for function ScreenSegmPlane2()">GenPal4Plane()</a> function. </p><dl class="section note"><dt>Note</dt><dd>To scroll image, set virtual dimension wrapx and wrapy, then shift offx and offy. </dd></dl>

<p>Set video segment to 2x4 bit color attribute per 8x8 pixel sample graphics. </p>
|
|
<p>Graphical mode with attributes (GF_ATTRIB8). This mode is known from ZX Spectrum computers. The 'data' parameter is a pointer to the pixel data. This corresponds to the monochrome display mode, where each bit distinguishes whether foreground or background color is used. The 'attr' parameter is a pointer to an array of color attributes. The color attribute is a byte, where the lower 4 bits represent the foreground color and the upper 4 bits the background color. The attribute is converted to a colored pixel using the palette table 'pal', which is an array of 16 bytes of colors. Each attribute specifies the foreground and background colors for a group of 8 x 8 pixels. Thus, for every 8 bytes of pixels, there is 1 byte of color attributes. The 'wb' parameter here specifies the line width in bytes for both the pixel array and the attribute array. The difference is that the address in the attributes array is not incremented after each line, but after 8 lines.<br />
|
|
<br />
|
|
Although there is no program in the PicoVGA library utilities that prepares an image in attribute mode, there is an internal function Attr8Conv that converts an image in 16 colors to attribute mode. Thus, the image is attached to the program as a 16-color image, and the conversion function is used to prepare a copy in RAM. </p><dl class="section note"><dt>Note</dt><dd>To scroll image, set virtual dimension wrapx and wrapy, then shift offx and offy. </dd></dl>

<p>Set video segment to tiles with perspective. </p>
|
|
<p>Tile graphics with 3D perspective. Similar to the previous function, it is used to display terrain with 3D projection. It uses tile definition instead of 8-bit graphics. This allows the display of very large terrains. The 'map' parameter is a pointer to a map of tiles - tile indices 0 to 255. The width and height of the map must be powers of 2 and are specified as the number of mapwbits and maphbits. Tiles must have a square dimension, which must also be a power of 2. The tile dimension is specified by the tilebits parameter as the number of dimension bits. The 'tiles' parameter is a pointer to an image with a pattern of tiles arranged in 1 column of tiles. The 'horizon' parameter specifies the horizon offset over the segment boundary / 4. A positive number represents the horizon offset, a negative number will invert the perspective (can be used to display the sky). A zero value turns off the perspective - in this case the function is similar to the function for displaying an image with a transformation matrix (the array of tiles can be rotated, skewed, etc). </p><dl class="section note"><dt>Note</dt><dd>Use default settings of parameters: offx = 0, offy = 0, wrapx = segment width, wrapy = segment height </dd></dl>
