I managed to get around this with 'Stationary Text', to handle simple images like a company logo or a pencil sketch, attached a screen shot of a Apple logo, Peter Steidlmayer and a picture of my dog in "Stationary.png" 1, use an online ASCII art program like 'Glass Giant' to convert your image into text. 2, paste text into 'Stationary Text', choose a font that all letters have equal width, and set size to 1. 3, pick up what ever colour you like. (the Apple logo consists 6 pieces of 'Stationary Text' on top of another) You don't want your picture be too big, because maximum lines 'Stationary Text' can display is 125, (125 vertical 'pixels') Human faces could be a bit tricky, you will have to convert the image to pencil sketch style first, by using a image processing program like GIMP, so it would have a realistic looking. For larger images, as the example shows in Image.png, size of 400x500 pixels, you need a custom study to display text file by compiling following code, change the font name (Noto Mono), folder location and size of text file (320K) if necessary: #include "sierrachart.h"
SCDLLName("ImageToText") SCSFExport scsf_ASCII_Art(SCStudyInterfaceRef canvas) { SCInputRef HorizonPos = canvas.Input[0]; SCInputRef VerticalPos = canvas.Input[1]; SCInputRef TextColor = canvas.Input[2]; SCInputRef FilePath = canvas.Input[3]; if (canvas.SetDefaults) { canvas.GraphName = "ASCII Art"; canvas.GraphRegion = 0; HorizonPos.Name = "Horizontal Position"; HorizonPos.SetInt(12); VerticalPos.Name = "Vertical Position"; VerticalPos.SetInt(98); TextColor.Name = "Text Color"; TextColor.SetColor(0, 0, 0); FilePath.Name = "ASCII Text File"; FilePath.SetPathAndFileName("C:\\SierraChart\\ASCII\\"); return; } if (!canvas.HideStudy && !canvas.Index) { char TextPixels[320000] = {}; int FileHandle = 1; unsigned int *p_BytesRead = new unsigned int(0); canvas.OpenFile(FilePath.GetPathAndFileName(), 2, FileHandle); //Open Mode: 2 (open for read only), canvas.ReadFile(FileHandle, TextPixels, 320000, p_BytesRead); canvas.CloseFile(FileHandle); s_UseTool Pencil; Pencil.Clear(); Pencil.DrawingType = DRAWING_TEXT; Pencil.LineNumber = 2; //has to be greater than 0, set 0 will cause repetitive drawing Pencil.UseRelativeVerticalValues = 1; Pencil.BeginDateTime = HorizonPos.GetInt(); Pencil.BeginValue = VerticalPos.GetInt(); Pencil.AddMethod = UTAM_ADD_ALWAYS; Pencil.Color = TextColor.GetColor(); Pencil.FontSize = 1; Pencil.Text = TextPixels; Pencil.FontFace = "Noto Mono"; canvas.UseTool(Pencil); } } Date Time Of Last Edit: 2024-06-01 03:53:33
