Created page with "= Action = Start the operation of graphics primitive at the specified coordinates in pixel precision. <..."

New page

= Action =

Start the operation of graphics primitive at the specified coordinates in pixel precision.

 

 

= Syntax =

Vertex2ii x, y, handle, cell

 

 

= Remarks =
<div style="padding: 0px; margin: 0px;">
{| cellspacing="0" cellpadding="0" border="0" style="border: none; border-spacing: 0px; border-collapse: collapse;"
|- style="vertical-align: top;"
| valign="top" width="53" style="width: 53px; border: 2px solid rgb(0, 0, 0);" |
x

| valign="top" width="367" style="width: 367px; border: 2px solid rgb(0, 0, 0);" |
x-coordinate in pixels, from 0 to 511

|- style="vertical-align: top;"
| valign="top" width="53" style="width: 53px; border: 2px solid rgb(0, 0, 0);" |
y

| valign="top" width="367" style="width: 367px; border: 2px solid rgb(0, 0, 0);" |
y-coordinate in pixels, from 0 to 511

|- style="vertical-align: top;"
| valign="top" width="53" style="width: 53px; border: 2px solid rgb(0, 0, 0);" |
handle

| valign="top" width="367" style="width: 367px; border: 2px solid rgb(0, 0, 0);" |
Bitmap handle. The valid range is from 0 to 31. From 16 to 31, the bitmap handle is dedicated to the FT800 built-in font.

|- style="vertical-align: top;"
| valign="top" width="53" style="width: 53px; border: 2px solid rgb(0, 0, 0);" |
cell

| valign="top" width="367" style="width: 367px; border: 2px solid rgb(0, 0, 0);" |
Cell number. Cell number is the index of bitmap with same bitmap layout and format. For example, for handle 31, the cell 65 means the character "A" in the largest built in font.

</div>
 

The Vertex2II command only allows positive screen coordinates.

If the bitmap is partially off screen, for example during a screen scroll, then it is necessary to

specify negative screen coordinates (with Vertex2F).

 

The handle and cell parameters will be ignored unless the graphics primitive is specified as bitmap by command [[Begin G]], prior to this command.
