Here is the test image where you can see the text does not size properly inside the rounded corner image on the top and bottom. The code I wrote is below.
Yes. Here is the sample code below that produces the image above. Please tell me how I can resize the text within the bounds of the rounded corner image on top and bottom. Any help is much appreciated.
Code: Select all
private void TextOnImage()
{
var image = new MagickImage(MagickColors.Red, 1000, 1000);
MagickImage imageresult;
MagickImage modimage;
try
{
using (var images = new MagickImageCollection())
{
int widthOfImage = GetProperFontSize(image);
var headerSnippetreadSettings = new MagickReadSettings()
{
BackgroundColor = MagickColors.LightBlue,
FontFamily = "Showcard Gothic",
FontPointsize = widthOfImage,
FillColor = MagickColors.Black,
FontWeight = FontWeight.Bold
};
// This will make the background of the label Khaki.
var readSettings = new MagickReadSettings()
{
BackgroundColor = MagickColors.LightBlue,
FontFamily = "Helvetica-Condensed-Light", // -font Helvetica-Condensed-Light
FontPointsize = widthOfImage, // -pointsize
FillColor = MagickColors.Black,
FontWeight = FontWeight.Bold
};
// Create the label image.
var branding = new MagickImage("label:MyDomain.com", readSettings);
// Create the label image.
var topheading = new MagickImage("label:Our Site Is Full of Great Cooking Tips", headerSnippetreadSettings);
// Create the label image.
var bottomheading = new MagickImage("label:Great Cooking Tips From Our Kitchen to Your Table", headerSnippetreadSettings);
branding.Extent(image.Width, 100, Gravity.Center);
topheading.Extent(image.Width, 100, Gravity.Center);
bottomheading.Extent(image.Width, 100, Gravity.Center);
// add the images to the collection
images.Add(topheading);
images.Add(image);
images.Add(bottomheading);
images.Add(branding);
// Append the images to create the output image.
using (var result = images.AppendVertically())
{
imageresult = new MagickImage(result);
// imageresult gets disposed of in the rounding code below, so need to write the imageresult to a new image
