C# - Converting floats to pixels

[sathenzar]

Hey I have an image scaling feature, problem is it requires floats (ScaleTransform(float scaleX, float scaleY)). I need to have a formula that takes the width of an image and finds the float 0.10, 0.20, etc required to be used to turn the width to 204.0 pixels. Any ideas?

This should work. If I understand your question correctly, you're trying to find the scaling percentage for any width image so that the final width is 204 px. Try this equation:

204 = width * scale%

so:

scale% = 204/width

And the scale% is the float you want. Also, make sure you're not dividing integers or else you won't get any decimal places. So, just make sure to convert the width to a float: Convert.ToFloat(width) before dividing 204.0 by it. Hope that helps.
