I am working on a PowerShell script to make images of characters (sort of like flashcards) in bulk.
And I am running into an issue I have seen before, and that is characters look very dirty. For example:
The large character looks good, but I believe this is only because of its size. If I enlarge the text on the right it looks similarly good. But I want the text to be this size.
I have used the following two methods to try and clean up the text, to no effect:
$grph.SmoothingMode.value__ClearTypeGridFit
The other approach that I have used:
$grph.CompositingQuality = [System.Drawing.Drawing2D.CompositingQuality]::HighQuality
$grph.InterpolationMode = [System.Drawing.Drawing2D.InterpolationMode]::HighQualityBicubic
$grph.SmoothingMode = [System.Drawing.Drawing2D.SmoothingMode]::AntiAlias
I believe this is more of an artifact from cleartype fonts than a code issue, but I am looking for help.
The complete script:
- Read CSV File (UTF-8 is supported thanks to LibreOffice)
- For each line in CSV, create the image. This is the Foreach statement that does the image creation.
$List | ForEach-Object {
$Name = $_.Name
$Out = "$Path\$Name.png"
$imgWidth = 270
$imgHeight = 450
$img = New-Object System.Drawing.Bitmap $imgWidth, $imgHeight
$fontK = New-Object System.Drawing.Font "Meiryo", 85
$FontAll = New-Object System.Drawing.Font Meiryo, 35
$BrushBG = [System.Drawing.Brushes]::Transparent
$BrushFG = [System.Drawing.Brushes]::Lime
$grph = [System.Drawing.Graphics]::FromImage($img)
$grph.CompositingQuality = [System.Drawing.Drawing2D.CompositingQuality]::HighQuality
$grph.InterpolationMode = [System.Drawing.Drawing2D.InterpolationMode]::HighQualityBicubic
$grph.SmoothingMode = [System.Drawing.Drawing2D.SmoothingMode]::AntiAlias
$grph.FillRectangle($BrushBG,0,0,$img.Width,$img.Height)
$kanji = $_.kanji
$grph.DrawString([String]$kanji, [System.Drawing.Font]$fontK, $BrushFG, [int]0,[int]0)
$kun = $_.kunyomi
$fontOn = New-Object System.Drawing.Font "Meiryo", 36
$kunWidth = [System.Windows.Forms.TextRenderer]::MeasureText($kun, $fontOn)
$kunLeft = $imgWidth - $kunWidth.Width
$grph.DrawString([String]$kun, [System.Drawing.Font]$fontOn, $BrushFG, [int]$kunLeft,[int]0)
$pKun = $_.pronounceKun
$pKunSize = [System.Windows.Forms.TextRenderer]::MeasureText($pKun, $fontOn)
$pKunLeft = $imgWidth - $pKunSize.Width
$grph.DrawString([String]$pKun, [System.Drawing.Font]$fontOn, $BrushFG, $pKunLeft,$kunWidth.Height)
$grph.Dispose()
$img.Save($Out)
Write-Output $Name, $ony
}
I removed the code for parts of the image not shown, but it is essentially duplicate code.
How can I make the hiragana ひ and the "hi" not have theat black jagged outline?
