BlendMask problem - UAAA

[mchirkov]

Hello everyone,

please help me to understand what I am doing wrong when creating the blendmask (see attachment).

Here's my inf file:

[Source]
Type = MultiSource
NumberOfSources = 2

[Source1]
Type = BMP
Layer = Imagery
SourceDir = "."
SourceFile = "L16X93561X93608Y47971Y48006.BMP"
Variation = All
NullValue = 255,255,255
SamplingMethod = Gaussian
ulyMap = 43.3830937738284
ulxMap = 76.9729614257812
xDim = 1.07288360595692E-05
yDim = 7.80209651075969E-06
Channel_BlendMask = 2.0


[Source2]
Type = TIFF
Layer = None
SourceDir = "."
SourceFile = "L16X93561X93608Y47971Y48006_B.TIF"
NullValue = 0,0,0
SamplingMethod = Gaussian
ulyMap = 43.3830937738284
ulxMap = 76.9729614257812
xDim = 1.07288360595692E-05

Thanks!

Hi Mike.

You might take out the

NullValue = 0,0,0


in the Source2. See if that works. Your blendmask should be 8-bit black and white, or grayscale.

Thanks, Dick. I have done that - still no change. Nothing works. I have even tried to compile my photo scenery on another computer - exactly the same result. Not sure what else to do.

Is your blend mask a gray scale image?? Where is it getting that red colour from?

 

[mchirkov]

Thanks for the hints. I still couldn't figure out the problem. The red stuff is gone once I have taken out the NullValue strings. Now the image looks like the attached. As you can see there's no blending yet. What am I doing wrong this time?

The TIF files are all grayscale. The BMP file is 24-bit.

The problem is resolved. Basically what was happening was that I selected the area to create map from the background from SBuilderX and then edited the resulting BMP file to cut out everything unnecessary. The next step was to create a gray scale TIf blend mask. That's where the problem occurred. I was using premade Adobe Photoshop action script which made a gradient transition in color from white to black based on selected area which had to be filled with white first. The problem was that I applied the script for the whole selection without prior contracting the marquee by the width of the gradient fill (about 200 pixels).
After I introduced the change, everything began to blend in very nicely.

Thanks for everyone's attention to this post!
